L4M7 Whole Life Asset Management Question and Answers

Explanation

Consignment stock is stock legally owned by one party, but held by another, meaning that the risk and rewards regarding to the said stock remains with the first party while the second party is re-sponsible for distribution or retail operations. Ownership of consignment stock is passed only when the stock is used (issued or sold in the case of a shop). Unused stock in a warehouse may be returned to the supplier when it concerns standard manufactured products. With customer specific items, agreements concerning returning products, should be negotiated.

Explanation

Safety stock is the stock held as a contingency or insurance against disruption or unexpected de-mand. Holding safety stock reduces the risks of stockouts, when an organisation is unable to meet an order or continue production due to lack of finished goods or input materials.

For single items, an extra investment in inventory (higher levels of safety stock) will always in-crease customer service levels. Conversely, higher service levels imply larger quantities of safety stocks and an increased investment in inventory. (Procurement and Supply Chain Management - 9th Edition)

However, high levels of safety stocks also increase the inventory cost. There must be a balance between inventory costs and customer service. Thus, calculating the should-be safety stock based on a determined service level has long been recommended by many professionals.

Explanation

ABC analysis is an approach for classifying inventory items based on the items’ consumption val-ues. Consumption value is the total value of an item consumed over a specified time period, for example a year. The approach is based on the Pareto principle to help manage what matters and is applied in this context:

- A items are goods where annual consumption value is the highest. Applying the Pareto principle (also referred to as the 80/20 rule where 80 percent of the output is determined by 20 percent of the input), they comprise a relatively small number of items but have a relatively high consumption value. So it’s logical that analysis and control of this class is relatively intense, since there is the greatest potential to reduce costs or losses.

- B items are interclass items. Their consumption values are lower than A items but higher than C items. A key point of having this interclass group is to watch items close to A item and C item classes that would alter their stock management policies if they drift closer to class A or class C. Stock management is itself a cost. So there needs to be a balance between controls to protect the asset class and the value at risk of loss, or the cost of analysis and the potential value returned by reducing class costs. So, the scope of this class and the inventory management policies are determined by the estimated cost-benefit of class cost reduction, and loss control systems and processes.

- C items have the lowest consumption value. This class has a relatively high proportion of the total number of lines but with relatively low consumption values. Logically, it’s not usually cost-effective to deploy tight inventory controls, as the value at risk of significant loss is relatively low and the cost of analysis would typically yield relatively low returns.

Explanation

Raw materials are basic input materials - they are only processed limitedly or have not been pro-cessed at all. Their values are equal to acquisition cost and are the lowest value of stock held.

Secondary components are the products that are combined with others to produce the finished goods. They are acquired in the processed state. Their value is higher than raw materials, but still at acquisition cost.

Work in progress is the stock part-way through manufacture that has not been finished. It is typically not completed yet, so it doesn't have full value. But the costs of processing already carried out makes it more valuable than materials and components.

Finished goods are completed and ready to be used or sold. Finished goods are the most expensive and need to be stored in good conditions.

Explanation

Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities.

Bill of materials (BOM) is an important component of MRP. BOM is also known as product struc-turer. This lists all the items that comprise each assembly and sub-assembly that make up the final product or end item. Therefore, MRP is commonly used to manage dependent demand stock.

Explanation

Two-dimensional (2D) barcodes look like squares or rectangles that contain many small, individual dots. This has many different types (i.e. Data matrix, QR codes, Aztec code,...) and several different standards in use (i.e. GS1 standards, ISO/IEC 18004:2015). It can be substituted for 1D barcode, but it has the capability to hold a larger amount of data. For examples, GS1 Data Matrix can contain 3116 Numeric characters or 2335 Alphanumeric characters while GS1-128 barcode has maximum capacity of 48 characters.

Like 1D barcodes, 2D barcodes are also machine-readable with dots/squares and spaces. They have symbology like this:

Since the code is two dimensional, conventional laser scanner can't read it. 2D barcodes require imaging scanner to read.

2D barcodes can be also used for different purposes throughout the supply chain: identifying prod-ucts/SKU (single unit, packaged or pallet), identifying content of a purchase order or delivery, identifying the batch number from which the item originates, identifying the manufacturer, country of origin etc, tracking status of an order, shipment or delivery

Explanation

The net requirements are worked out using the following equation:

Net requirements = Total requirements - Available inventory

Where:

Total requirements = Gross requirements

Available inventory = Inventory on-hand + Units on-order

In the other words: Net requirements = Gross requirements - Inventory on-hand - Units on-order

Inventory on-hand is also known as Inventory level, whereas Units on-order can be called Scheduled receipt.

Just-in-Time (JIT) aims to:

Improve quality by ensuring defect-free products that meet customer expectations.

Reduce inventory levels: The JIT approach minimizes holding costs by producing and delivering goods as needed.

Whole-life asset management values JIT for optimizing inventory control, reducing waste, and enhancing quality while keeping storage costs minimal.

Hiring offers the advantage that the repair and maintenance responsibility usually lies with the equipment owner (lessor). This helps the hiring organization avoid costs associated with unexpected repairs and maintenance, beneficial in managing operating expenses and ensuring equipment uptime.

Whole-life asset management encourages hiring for short-term or temporary use, where maintenance responsibilities can be deferred to the provider, thus lowering total ownership costs for the user.

Obsolescent stock refers to items that are outdated but may still have some use. Redundant stock, on the other hand, is no longer useful or required by the organization. Effective whole-life asset management requires identifying and managing both types of stock to minimize waste and optimize storage.

Explanation

RFID tags have very limited range. The following table was extracted from Wikipedia:

RFID tags can be used to do the following:

- Track individual items

- Track boxes of products, cages of products and pallet

- Track containers with multiple loads

- Locate equipment within a building

- Trigger alarms should equipment or stock be removed without authorisation.

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate. RFID chips are very small integrated circuit incorporating a small memory capability - many are smaller than 2mm square and 2mm thick. Despite its size, many can hold 2000 characters of data. Many retailers simply use the tag as a thick label and print both sides with product information and perhaps a barcode.

It is important to note that there are multiple standards in use for RFID - some of these are standardised for industries but there are also national standards in operations. These standards need to be investigated before investment as not all readers work with all cards. GS1 is a non-for-profit organisation which make the standards for barcodes and RFID.

Explanation

The total cost of ownership would be the sum of all estimated costs.

The costs are as the following:

- Purchase price: $1,000

- Electricity consumption: $200

- Extended warranty: $75

Total expense = $1,000 + $200 +$75 = $1,275. Then subtract the resale price from this sum, the total cost of ownership is $1,025.

While storage space is important, traffic flow and accessibility are crucial for efficient warehouse design. Proper layout ensures safe, quick movement of goods and minimizes bottlenecks, reducing operational costs and enhancing efficiency. In whole-life asset management, effective space utilization and efficient layout planning are key for long-term warehouse performance.

Holding costs include expenses associated with storing inventory. These typically comprise:

Damaged goods: Losses due to items being stored improperly or deteriorating over time.

Storage space: Costs of renting or maintaining warehouse space.

Insurance: Fees for insuring stored items against potential risks.

These costs are integral to whole-life asset management, as they impact overall inventory and storage expenses.

Explanation

Temporary warehousing (or 'Very short-term warehousing') is offered in the market where organ-isation makes their requirements for space open online to offers or bids for available space. This appears to be an emerging market and service providers in the UK and USA typically quote a price per pallet per week with some also requiring a 'transaction fee' for movements of each pallet in and out.

Consignment stocking is a facility offered by a supplier to a buyer to allow a delivery of stock to the buyer with payment only after it is used or sold to a customer.

Double-deep pallet racking and carousel-style storage are two tools that leverage space within a warehouse:

Explanation

Purchase order lead time (POLT) refers to the number of days from when a company places an order for production inputs it needs, to when those items arrive at the manufacturing plant.

LO 2, AC 2.3

The triple bottom line (TBL) framework evaluates organizational performance based on:

Economic sustainability: Focusing on financial stability and profitability.

Environmental sustainability: Ensuring that business activities minimize negative ecological impacts.

Social sustainability: Committing to ethical practices and community well-being.

TBL aligns with whole-life asset management principles by incorporating sustainability into asset use and disposal, ensuring long-term organizational value beyond just financial metrics.

Explanation

The system of slip sheet load handling involves the use of a thin sheet of material, the slip sheet, as a base on which items are assembled as a unit load for handling, storage, and transport. The slip sheet is used in conjunction with a pallet, if desired, at certain stages in the distribution cycle. If all lift trucks in the cycle are equipped with the proper attachment, an appropriate slip sheet is the only material handling base required. Slip sheet requires special push pull accessories and usually use thin and wide forks.

Shrink wrap, also referred to as shrink film or shrink wrap, is a versatile polymer material used for the packaging of finished goods. Heat is applied to the film – by either a conveyor heat tunnel or an electric or gas heat gun – which catalyzes the film to shrink tightly around the item placed within. This process results in a clear, durable barrier of protection around the product.

Post pallets have a simple metal structure with four uprights and substantial feat to take the load. These may be free standing, but many are designed for the feet to interlock with the posts of another post pallet so that the stack can be created.

Including end-of-life packaging costs is essential when dealing with hazardous materials, as they often require special packaging and labeling for safe disposal. Whole-life asset management considers disposal costs in the total lifecycle cost to ensure compliance with regulations and prevent environmental harm.

Explanation

Materials that will not easily deteriorate, are generally stored in open or fairly covered areas (stockyard). The materials are usually in bulk, like steel plates or coils casting, timber coal, steel barrels, cable drums, piping, lampposts, lorries, etc.

Stockyards are open or semi-covered areas that are used for the following:

- Bulk loose or packaged materials

- Bulky or oversized items that may be difficult to move inside

- Materials that may require specialised handling, loading or unloading

Below image shows the example of a stockyard that stores loose coal and its handling system.

LO 1, AC 1.1

Explanation

Available inventory (or Inventory position - IP) is equal to inventory on-hand plus quantity on order minus backorder (if any)

Dependent demand items rely on the internal production requirements of an organization. These items:

Depend on user department production levels: Demand is driven by the needs of the production line.

Can be managed using JIT systems: Just-in-Time inventory helps optimize stock levels based on immediate production needs, reducing holding costs and minimizing waste.

Dependent demand items differ from independent demand items, where demand is customer-driven rather than production-driven, emphasizing demand predictability and timely procurement.

Writing off obsolete stock is standard practice as it no longer holds any value for the organization. This allows for accurate financial reporting by removing items that cannot be sold or used from the balance sheet. Including it in closing stock would misrepresent asset values, while leaving it unsorted wastes valuable space.

Whole-life asset management emphasizes disposal or recycling options to avoid holding costs for unused assets, reducing storage costs and improving warehouse efficiency.

Low stock levels can lead to:

Delays and higher fulfillment costs: When stock is insufficient, emergency orders and expedited shipping may be necessary, increasing costs.

Stockouts during high demand: Insufficient inventory can lead to missed sales opportunities, negatively impacting customer satisfaction.

Whole-life asset management seeks to balance inventory levels to avoid stockouts while minimizing holding costs.

A life cycle asset management plan provides a comprehensive framework for planning, budgeting, and resource allocation throughout the asset's life. It considers costs from acquisition to disposal, ensuring that assets are managed efficiently and cost-effectively over their full lifecycle, which is central to whole-life asset management strategies.

Indirect supplies support operations but are not part of the finished product. For a bottling plant, items like lubricants for machine maintenance and office supplies are indirect supplies, as they aid in operation but do not enter the final product. Managing these supplies in whole-life asset management is critical for cost efficiency and operational support.

Explanation

VACUUM LIFTER uses the vacuum pad which attaches itself to a product. The suction force al-lows the product to be lifted (and rotated and placed). Vacuum lifters are used for moving and positioning glass sheets, but are also seen lifting boxes, plastic sacks, sheets of building materials and pipework. Some models feature hydraulic arms which allow easy movement of the lifted load. The lifting system will have a number of sucker pads and vacuum capability which determines the maximum weights and largest items that can be lifted.

DOLLY consists of stack and sets of wheels (either casters or rollers) under the stack that allow the dolly and the heavy object on top of it to move easily and smoothly. For moving in a straight line, rollers is ideal. If you want to move manoeuvrability, dolly with sets of casters will let you swivel and turn.

SACK TRUCK (hand truck) is an L-shaped box-moving handcart. It comprises a small base plat-form with two wheels at the base and a larger vertical structure. A small ledge to set objects on flat against the floor when the sack truck is upright. When moving, the truck and object are then tilted backward based on the vertical structure until the weight is balanced over the large wheels, making otherwise bulky and heavy objects easier to move.

PALLET STACKER is designed to lift and stack pallets. This one is fully mobile so can move easily around the warehouse. An operator would typically sit or stand while driving like a counter-balanced, reach or straddle lift truck.

LO 1, AC 1.3

RFID technology, while advanced, has several limitations:

Cost: RFID can be expensive, particularly for smaller operations.

Reading limitations with certain materials: Liquids and metals can interfere with RFID signals, limiting their effectiveness.

Interference: Devices such as radios can disrupt RFID systems, reducing reliability.

In whole-life asset management, these disadvantages may affect the decision to implement RFID, especially in cost-sensitive or materials-sensitive applications.

Variable periodic reviews enable ATT to manage seasonal goods effectively by adjusting ordering based on:

Lead times and sales volume: Classifying products by these factors helps in planning, aligning with varying supplier delivery times and unpredictable sales demand.

Implementing a JIT or MRP system would require more sophisticated management tools, making option C the most feasible. This method aligns with whole-life asset management by supporting efficient inventory planning while minimizing stockouts or overstock situations.

Barcode technology has several limitations:

Requires line-of-sight scanning (LOS): Barcodes must be directly visible to scanners, reducing flexibility in scanning items in bulk.

No read/write capabilities: Barcodes can only store static data, limiting functionality in dynamic inventory environments.

Labour-intensive: Each barcode must be scanned individually, making it time-consuming in high-volume environments.

Despite these limitations, barcodes are widely used due to their low cost. Whole-life asset management often considers RFID as a more efficient alternative to barcodes, especially in high-value asset tracking.

Explanation

According to L4M7 study guide, acquisition costs in procurement are the costs associated with the activities involved in a purchase. A buying organisation incurs acquisition costs in low-value purchases as well as high-value purchases. The following purchases tend to have lower acquisition costs:

- Straight re-buy from a current supplier

- Purchase of standard catalogued products

Otherwise, any purchases of high value, high-risk items generally require greater attention of buying organisation and thus, they are likely to have higher acquisition costs. Spot purchase of a technically complexed machinery, Purchase of ERP system and Procurement of construction projects are examples of high-value, high-risk purchases.

Explanation

Fixed-Time Period System (or Periodic Review system) is the inventory management system in which inventory is checked in fixed time periods, T, and the quantity ordered varies. The system also contains a target inventory level, R, which is restored when order received. The order quantity is calculated as:

Q = R – IP

where: Q = order quantity

R = target inventory level

IP = inventory position

Inventory position (IP) is equal to inventory on-hand plus quantity on order minus backorder (if any)

The order quantity varies because the inventory position at each review point differs from each other.

Explanation

There are two main processes of recycling – open loop recycling and closed loop recycling.

Open Loop Recycling

Open loop recycling is a method that delays disposal by converting manufactured goods and spent materials into both new raw materials, which can be used for a manufacturing purpose, as a fuel source for a different manufacturing process and waste products.

Typically, materials recycled through open-loop recycling will be used for purposes different from their original purpose.

This means that the input into the recycling process is converted to a new raw material, which can be used as an input into another manufacturing process.

Materials in an open loop recycling process are treated using various forms of treatment including heat, chemical reactions, or physical crushing.

Closed Loop Recycling

Closed loop recycling is a process where waste is collected, recycled and then used again to make the same product it came from. This process is restorative and regenerative by design and aims to keep materials at their highest utility and value always.

Closed loop recycling is focused on resource sustainability, which means that recycling of a material can be done indefinitely without degradation of properties. In this case, conversion of the used product back to raw material allows repeated making of the same product, which helps hazardous waste generators reduce carbon footprint and achieve corporate sustainability initiatives.

Closed-loop recycling is common in specialized industries, such as the computer and battery industries, which use expensive or complex goods that cannot easily be broken down post-consumption into constituent materials.

A prime example of a closed-loop recycling process is the recycling of aluminum cans. Aluminum can be recycled to form new cans with little material degradation or waste creation.

Explanation

Unit load is a term used to describe grouping of different items into a convenient stack or stacks which make them easy to handle and store. Typically this involves pallets and/or the plastic wrap-ping of a load.

Stacker is designed to lift and stack pallets. This one is fully mobile so can move easily around the warehouse. An operator would typically sit or stand while driving like a counterbalanced, reach or straddle lift truck.

A load cell is a type of transducer, specifically a force transducer. It converts a force such as ten-sion, compression, pressure, or torque into an electrical signal that can be measured and standard-ized.

Unit price is the price of a single product or service, used for example when buying several things together to refer to the price of each one.

Explanation

It is important to ensure safe working in storage facilities, and access to higher shelves or racking presents a challenge. Lifting at full reach becomes a problem at relative low weight. There can also be danger for other workers who are around someone working at height, from the movement of equipment or dropping stock from a height.

Scissor platforms are used in high-roof warehouses to gain access to lighting, high-racking units and sections of wall and roof.

ORDER PICKER is manual or powered device - some with ride-on capability and some without. This allow for low-level, medium-level and high-level picking of various items. Many are equipped with forks to allow transfer capability of larger picked boxes. Higher-level and narrow or very narrow -aisle versions have the ability to elevate operators on the front platform to higher racking to pick items.

Grabs are designed to hold stock either width-wise or from above. These are either specific devices designed for grabbing materials or are available as an accessory to forklift trucks.

Carousels are space-efficient, rotating devices which allow access to a large range of product from a single location. Designs are variable, with carousels rotating horizontally or vertically until the required items can be retrieved.

Stacker-cranes are designed for the automated storage and retrieval of unit loads, in high-bay warehouses. They travel in aisles equipped with guide rails, electrical supply, data transmission and control systems. To ensure the storage and retrieval functions, the stacker-crane carries out three types of movement : long-travel, lifting and picking.

Explanation

ISO 18602:2013 is about Packaging and the environment — Optimization of the packaging system. ISO 18602:2013 specifies requirements and a procedure for assessment of packaging to ensure that the weight or volume of its material content is optimized consistent with the functions of packaging. This is one of several options for reducing the impact of packaging on the environment.

It also provides methodologies and procedures for

- determining the amount and minimization of substances or mixtures hazardous to the environ-ment, and

- determining the amount of four heavy metals (lead, cadmium, mercury, hexavalent chromium) in packaging.

The optimum balance in this standard weighs the environmental impact of losses that may happen with no packaging or inadequate packaging against the environmental impact from excess packag-ing.

The process for packaging design, including material selection, is not part of ISO 18602:2013.

The procedure for applying ISO 18602:2013 is contained in ISO 18601.

Explanation

Direct and indirect costs of holding inventory include the following:

- Acquisition costs

- Holding costs: There are 2 different types of holding costs: costs related to the value of the goods (including opportunity costs, costs of insurance, losses due to product deterioration, etc) and costs related to the physical characteristics of this inventory.

- Costs of stockouts

When selecting a warehouse location, it’s essential to consider:

Cost: The expense of the location directly impacts the budget.

Access to transport networks: Proximity to transportation infrastructure facilitates efficient shipping and receiving.

These factors align with whole-life asset management principles by ensuring cost-effective and accessible storage solutions, contributing to reduced transportation costs and improved logistics.

Explanation

There are many different factors that must be considered when assessing warehouse and stock locations:

• Operating cost of the location or area

• Availability and suitability of warehouses

• Availability of manpower or labour

• Proximity to suppliers and customers

• Access to transport infrastructure (domestic and international)

• The political and security environment of the location

LO 1, AC 1.1

Explanation

There are different types of maintenance that organizations use to increase the uptime of their assets and utility of their facilities. Based on an organization’s budget, amount of resources, level of combined experience, and maintenance goals, one or more maintenance types are used.

Proactive types of maintenance

Preventive maintenance

Preventive maintenance is the most popular type of proactive maintenance. To start conducting preventive maintenance tasks (PMs), an organization does not need to purchase new technology if it already has a CMMS. This is not the case with predictive maintenance which requires condition monitoring sensors and new software integrations. However, with preventive maintenance, the or-ganization runs the risk of over-scheduling maintenance tasks because tasks are scheduled based on time rather than actual conditions. That said, preventive maintenance achieves 12% to 18% cost savings over reactive maintenance.

Predictive maintenance

Predictive maintenance (PdM) is what savvy maintenance teams aspire to have or are already im-plementing. The major barrier to PdM is the time it takes to implement rather than the cost of the technology itself. For instance, a vibration sensor that can identify imbalance, misalignment, and resonance issues only costs around $200. But the time it takes to install, integrate with other maintenance software, and adopt a culture around is not time that all organizations are willing to allocate. For those that do allocate the time, PdM provides an 8% to 12% cost savings over preventive maintenance.

Condition-based maintenance

Condition-based maintenance (CBM) is at the core of predictive maintenance but, on its own, does not rely on technology to determine the condition of an asset like PdM does. For instance, a manager may instruct an operator to monitor the condition of an asset and submit a work request when a specific condition is met. This approach may, or may not be, as reliable as predictive maintenance. An organization that has highly-trained operators may spot hazardous conditions better than an organization using PdM technology that doesn’t know what to look for.

Scheduled maintenance

Scheduled maintenance includes work that is scheduled on a calendar for completion. The most common type of scheduled maintenance is calendar-based preventive maintenance tasks. These are scheduled well in advance of completion. For instance, an asset with a monthly PM has twelve instances of scheduled maintenance in a given year. However, just because maintenance is scheduled does not mean it’s planned. Planned maintenance implies that a maintenance planner or other type of maintenance worker has fully planned for parts, materials, skills, and other resources to be available during the scheduled time window.

Planned maintenance

Planned maintenance is work that’s prepared for in advance of it taking place. According to an UpKeep survey, it’s also the most popular key performance indicator (KPI) to track. A high planned maintenance percentage indicates that a maintenance team will have resources available to complete work for the time/day the work is scheduled for. Having a high planned maintenance percentage also helps boost other maintenance KPIs like schedule compliance. More planned maintenance means more successful completion of scheduled maintenance.

Routine maintenance

Routine maintenance is a form of time-based maintenance and preventive maintenance, though some organizations differentiate between routine maintenance and preventive maintenance. They use the latter for smaller tasks (i.e. cleaning) performed at higher frequencies (hourly, daily) and the former for larger tasks (i.e. inspections) performed at lower frequencies (weekly, monthly, annually). Additionally, routine maintenance is performed by operators, janitors, and other staff member while preventive maintenance is performed by technicians. Non-routine maintenance includes maintenance that is performed reactively or only when needed based on an asset’s conditions.

Reactive types of maintenance

Emergency maintenance

Emergency maintenance occurs when an asset requires immediate attention in order to keep a facility operational or safe. This is the most reactive and intrusive type of maintenance as it pulls technicians away from other jobs and lowers schedule compliance. In extreme circumstances, emergency maintenance can set an organization back days depending on the scope of the repair, available parts, and the asset’s level of importance. To reduce the amount of emergency maintenance that is both unplanned and unscheduled, organizations adopt various forms of proactive maintenance.

Corrective maintenance

Corrective maintenance is inherently part of emergency maintenance because, when there is an emergency, something needs corrected or fixed. In this way, corrective maintenance is mostly reactive. However, it can also be proactive. If an asset with a condition monitoring sensor detects an issue, a work order is created and a technician is sent to correct it. Similarly, preventive maintenance is considered corrective maintenance if there is an issue to fix. This is rare though as PMs are often conducted when an asset is in good working order.

Other types of maintenance

Deferred maintenance

Deferred maintenance includes repairs and inspections that are put into a backlog due to limited budget and resources. While deferring maintenance saves money up front, the costs of not performing important maintenance compounds at 7% annually. Rising costs come from fines resulting from missed inspections and unscheduled downtime that brings production to a standstill. By far, deferred maintenance and emergency maintenance are the least desired types of maintenance.

Total productive maintenance

Total productive maintenance (TPM) is the broadest type of maintenance that targets more than the assets that need maintained. It also aims to improve employee satisfaction and overall morale in the workplace, specifically in manufacturing plants. TPM does this by increasing overall equipment effectiveness (OEE) and the amount of planned maintenance. More planned work means more workers have the resources they need to do their job, which means higher levels of satisfaction. TPM also leverages machine operators to participate in maintenance and take ownership of their equipment.

Explanation

Drum is the container for stock, which is usually cylindrical and can be made from a variety of materials. Contents are usually loose material or liquids

A picture containing tableware, kitchen appliance Description automatically generated

Tote box is the reusable storage box. These can be open or have lids or flaps to close them and come in a large variety of sizes and weight loadings.

A tote is ideal for holding and hauling items such as: tools, fasteners, bark dust, dry cement, cords, wires, smaller boxes,...

For larger and bulkier items, industrial containers make it easy to keep things stored and in one spot for transportation. Due to the metal interior, an industrial container is more appropriate for items that — unlike tools and small pieces of machinery — lack any surface sensitivity.

Solid containers like bins and totes are far from the only storage devices for the various materials that are needed in abundance at factories and warehouses. Another option is the storage bag, which can be used to hold bulk supplies of items until they’re needed for the department shelves or assembly lines.

Explanation

Lean thinking aims to remove wastes from work processes. Before diving into the 8 wastes, it is important to understand what waste is. Waste is any action or step in a process that does not add value to the customer. In other words, waste is any process that the customer does not want to pay for.

The original seven wastes (Muda) was developed by Taiichi Ohno, the Chief Engineer at Toyota, as part of the Toyota Production System (TPS). The seven wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing and Defects. They are often referred to by the acronym ‘TIMWOOD’. The 8th waste of non-utilized talent or ‘Skills’ of workers was later introduced in the 1990s when the Toyota Production System was adopted in the Western world. As a result, the 8 wastes are commonly referred to as ‘TIMWOODS’.

Multiple approval levels for a small purchase request is an example of over-processing since this adds more unnecessary work to users and procurement professionals.

Explanation

All risk management processes follow the same basic steps, although sometimes different jargon is used to describe these steps. Together these 5 risk management process steps combine to deliver a simple and effective risk management process.

Step 1: Identify the Risk. You and your team uncover, recognize and describe risks that might affect your project or its outcomes. There are a number of techniques you can use to find project risks. During this step you start to prepare your Project Risk Register.

Step 2: Analyze the risk. Once risks are identified you determine the likelihood and consequence of each risk. You develop an understanding of the nature of the risk and its potential to affect pro-ject goals and objectives. This information is also input to your Project Risk Register.

Step 3: Evaluate or Rank the Risk. You evaluate or rank the risk by determining the risk magni-tude, which is the combination of likelihood and consequence. You make decisions about whether the risk is acceptable or whether it is serious enough to warrant treatment. These risk rankings are also added to your Project Risk Register.

Step 4: Treat the Risk. This is also referred to as Risk Response Planning. During this step you assess your highest ranked risks and set out a plan to treat or modify these risks to achieve acceptable risk levels. How can you minimize the probability of the negative risks as well as enhancing the opportunities? You create risk mitigation strategies, preventive plans and contingency plans in this step. And you add the risk treatment measures for the highest ranking or most serious risks to your Project Risk Register.

Step 5: Monitor and Review the risk. This is the step where you take your Project Risk Register and use it to monitor, track and review risks.

The turning circle of the forklift truck and the size of the pallet it carries are primary factors in determining aisle width. The aisle width must accommodate forklift maneuvers for safe and efficient access to stored items. Whole-life asset management emphasizes warehouse layout planning to optimize space usage, reduce handling time, and enhance safety.

Explanation

The triple bottom line is a sustainability framework that examines a company’s social, environment, and economic impact (or People, Planet, Profit). ASI Ltd practice would reduce the waste into the environment as well as keep the business more profitable. So the correct answer should be Planet and Profit.

Explanation

Below is a formula from Toyota you can use to make an informed decision.

1. Start with the basic right-angle stacking width

2. Add the load length

3. Add 12 inches for clearance

The basic right-angle stacking width is the smallest amount of space a forklift needs turn in order to insert its forks into a pallet. You can find basic right-angle stack measurements in the equipment manual or by contacting TMHNC if your business is located in Northern California. This measurement does not include the length of the load or room need for clearance.

Load lengths vary depending on your application, products, etc. As a starting point, a standard pallet has a 48-inch load length. Always check your forklift’s data plate for the rated capacity (which is affected by attachments and other factors).

Adding 12 inches for clearance ensures you have enough room for your forklift’s turn radius and helps protect against damage from operator error and/or product that may hang over the edge of the pallet.

Explanation

A 'U' flow occurs when the goods receipt and dispatch functions are located at the same end of a warehouse building.

Products flow in at receiving, move in to storage in the back of the warehouse, and then to shipping, which is located at the adjacent to receiving on the same side of the building.

Items with higher throughput level are located closer to the loading bays. An example of a 'U' flow design can be seen in the diagram below.

Advantages of 'U' Flow

- Excellent utilization of dock resources because the receiving and shipping processes can share dock doors

- Facilitating cross-docking because the receiving and shipping docks are adjacent to one another and may be co-mingled

- Excellent lift truck utilization because put away and retrieval trips are easily combined and be-cause the storage locations closest to the receiving and shipping docks are natural locations to house fast moving items

- Yields excellent security because there is a single side of the building used for entry and exit

Explanation

Safety stock is also known as buffer stock. As this name suggests, this type of stock provides some kind of 'buffer', which means safety stock will help the business to reduce the shocks induced by volatile demand or disruption on the supply chain. In other words, safety stock will reduces the probability of stockouts. The following graph would explain the reason why an organisation should have safety stock:

As it is only the buffer against uncertainty, safety stock level should be equal to the deviation of demand or replenishment time. Safety stock should be able to accommodate variance of demand and variance of lead time.

Significant coding with sequential numbering assigns codes that reflect specific product attributes (e.g., wattage, type) with an added sequential number for unique identification. This approach facilitates easy identification and tracking, an essential feature in whole-life asset management for maintaining organized inventory records.

Explanation

Costs of operating an asset can widely vary. The following table is an example from Guide to Total Cost of Ownership, New Zealand Government:

Explanation

If the planning and mitigation measures fail and redundant or obsolete stock is identified, it needs to be removed from the current inventory location as quickly as possible. There are some methods to deal with these types of stock. The worst case scenario is disposal to landfill, which is inadvisable if it can be avoided, both from environment point of view and the financial costs of such disposal.

For example, the problem of obsolete pesticides remains extremely serious and urgent. Many of the stocks identified continue to deteriorate thereby giving rise to an ever escalating source of severe pollution and posing a threat to human health, the environment and development in particular. To reduce the impact of obsolete pesticides on environment, FAO initiated a project in Yemen in which a total of 262 tonnes of obsolete pesticides were removed from 20 different sites and successfully disposed of between March and June 1996. The major field operation was completed in six weeks during which period almost all obsolete pesticides were brought to a central location and subsequently shipped to the United Kingdom for incineration.

Explanation

Void filling is the general term giving to the challenge of filling the space left in a box after the products have been packed. This means that if there is no void filling material, the product inside can move around and could be damaged. Materials to fill voids to secure contents

• Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene.[5] Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point.[6] Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year.[7] Polystyrene can be naturally transparent, but can be coloured with colourants. Uses include protective packaging (such as packing peanuts and CD and DVD cases), containers, lids, bottles, trays, tum-blers, disposable cutlery[6] and in the making of models. Polystyrene is generally considered to be non-biodegradable. However, certain organisms are able to degrade it, albeit very slowly.

• Chips made of bio-degradable materials

• Absorbent and fire-resistant material

• Shredded paper, cardboard or wood-Based material

• Paper or cardboard rolls

• Bubble wrap

• Air-filled cushions

• Self expanding foam

Straps are used to group items into unit load. Polypropylene or polyester are the materials most often used. The wider the strap, the stronger it will be. Using more than one strap and straps for length and width will create a strong place for stock.

Explanation

Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities.

MRP software combines the master production schedule, the bill of materials and the inventory information to work out the net requirements (net MRP) of what to purchase or produce and when.

These net requirements are worked out using the following equation:

Net requirements = Total requirements - Available inventory

Where:

Total requirement = Gross requirements (gross MRP)

Available inventory = Inventory on hand + Units on order

In the other words, Gross MRP = Net MRP + Available inventory, so the answer should be "The gross MRP includes consideration of available inventory, whereas the net MRP does not"

Warehouse location selection depends on:

Land cost: Directly affects budget planning and long-term operational expenses.

Nature of items to be stored: Determines special requirements (e.g., climate control).

Access to transport: Proximity to transport hubs reduces logistics costs and improves efficiency.

These considerations are critical for effective whole-life asset management, optimizing operational costs and logistics.

Explanation

Many codes have integrated check digits. These are additional numbers or characters added to codes that a computer uses to verify the number is valid. The intention is to reduce the likelihood of miskeying an item and hitting an alternative live item. More often, a system is devised which a computer can calculate using combination of numbers.

Barcode is a graphic symbol used to convey data. Typically the characters in a barcode symbol consist of bars/space pattern. Barcode is the method of representing data in a visual, machine-readable form. Initially barcodes represented data by varying the width and spacing of parallel lines.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

A prefix is an affix which is placed before the stem of a word or a string. A product code may have prefix which indicates its group, country, origins, etc.

Explanation

According to Hines and Rich, value stream refers to specific parts of the firms that actually add value to the specific product or service under consideration. XYZ Ltd is mapping the value stream by analysing the value-adding activities that contribute to their most important product.

Postponement is a business strategy which maximizes possible benefit and minimizes risk by delaying further investment into a product or service until the last possible moment. An example of this strategy is Dell Computers' build-to-order online store. One of the earliest references to the concept was in a paper by Zinn and Bowersox in the Journal of Business Logistics. They highlighted five types: Labelling, Packaging, Assembly, Manufacturing and Time postponements.

Kanban (看板) (signboard or billboard in Japanese) is a scheduling system for lean manufacturing and just-in-time manufacturing (JIT). Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. Kanban is one method to achieve JIT. The system takes its name from the cards that track production within a factory. For many in the automotive sector, kanban is known as the "Toyota nameplate system".

Put simply, silo working occurs when several departments or groups within that organisation do not want to share information or knowledge with other individuals they work with.

Explanation

Stockout is a situation where an inventory item is not available when required. The costs associated with a stockout include the following:

- Lost of production output - there will be no production until the stockout is resolved (new stock is acquired). For factory operating 24/7 with no spare capacity, this lost output will not be able to be recovered.

- Costs of machine downtime and of overhead spread over a reduced level of output

- Costs of any action required to deal with the stockout...

- Loss of customer goodwill through inability to supply or late delivery

- Loss of sales or new orders

- Loss of market creditability

Outsourcing involves contracting a third party to manage storage or logistics functions, which allows the company to concentrate on core business activities. In this case, outsourcing the warehousing needs aligns with whole-life asset management, as it optimizes resources and mitigates the challenges of limited storage capacity.
