L4M7 Whole Life Asset Management Questions and Answers

Explanation

A cost-benefit analysis is a process businesses use to analyze decisions (such as capital investment). The business or analyst sums the benefits of a situation or action and then subtracts the costs associated with taking that action.

A cost-benefit analysis (CBA) should begin with compiling a comprehensive list of all the costs and benefits associated with the project or decision.

The costs involved in a CBA might include the following:

- Direct costs would be direct labor involved in manufacturing, inventory, raw materials, manufacturing expenses.

- Indirect costs might include electricity, overhead costs from management, rent, utilities.

- Intangible costs of a decision, such as the impact on customers, employees, or delivery times.

- Opportunity costs such as alternative investments, or buying a plant versus building one.

- Cost of potential risks such as regulatory risks, competition, and environmental impacts.

Benefits might include the following:

- Revenue and sales increases from increased production or new product.

- Intangible benefits, such as improved employee safety and morale, as well as customer satisfaction due to enhanced product offerings or faster delivery.

- Competitive advantage or market share gained as a result of the decision.

An analyst or project manager should apply a monetary measurement to all of the items on the cost-benefit list, taking special care not to underestimate costs or overestimate benefits. A conservative approach with a conscious effort to avoid any subjective tendencies when calculating estimates is best suited when assigning a value to both costs and benefits for a cost-benefit analysis.

Finally, the results of the aggregate costs and benefits should be compared quantitatively to deter-mine if the benefits outweigh the costs. If so, then the rational decision is to go forward with the project. If not, the business should review the project to see if it can make adjustments to either increase benefits or decrease costs to make the project viable. Otherwise, the company should likely avoid the project.

Explanation

Dependent demand is the requirement for stock item which is directly related to and therefore de-pendent upon the rate of production (examples are: raw materials, components, energy). The com-ponents in the scenario are dependent demand items.

Independent demand is the requirement for stock item which is not directly related to, and is therefore independent of rate of production.

Explanation

Just-in-time (JIT) purchasing is a systems approach for developing and operating the purchasing function. JIT purchasing along with the total quality management in many industries has been suc-cessful in reducing inventory and increasing the overall effectiveness of purchasing function and hence the productivity of manufacturing.

The just-in-time objectives of eliminating waste can be summarised in the 'five zeros: zero defects, zero set-up times, zero inventories, zero handling and zero lead times.

The correct answer should be 'In JIT purchasing, raw materials (or goods) are purchased so that products are delivered just as needed for production or sales' because it expresses that upstream activity (purchasing) only occurs as the downstream activity (production or sales) triggers.

Explanation

Maintenance can represent a significant portion of the cost in asset intensive organisations (such as Sidel - a food processor), as breakdowns have an impact on the capacity, quality and cost of operation. However, the formulation of a maintenance strategy depends on a number of factors, including the cost of down time, reliability characteristics and redundancy of assets. Consequently, the balance between preventive maintenance (PM) and corrective maintenance (CM) for minimising costs varies between organisations and assets. Nevertheless, there are some rules of thumb on the balance between PM and CM, such as the 80/20 rule.

Preventive maintenance is a type of proactive maintenance, while corrective maintenance is an example of reactive maintenance. Therefore, the answer should be "Balance between proactive maintenance and reactive maintenance".

Explanation

Net present value (NPV) is the 'today' net value that deprives from 'future' cash flow of an invest-ment or a capital purchase.

The following formula is used to calculate NPV

Chart Description automatically generated with low confidence

Where:

Rt is the net cash flow (cash inflow - cash outflow) during the period t

i is the discount rate

t is the number of time periods

As you can conclude from the above formula, the net present value increases when the numerators (net cash flows) increase and/or denominators (1+i) decrease. So the correct answer should be "Net cash flow during a time period increases"

The purpose of this exercise is to help you identify the factors that influence the net present value and how to increase/decrease NPV in real-world scenario.

Explanation

RFID tags are the small devices that can be embedded in labels or attached to tags which work with radio transmitters and/or receivers to identify themselves.

RFID tags can be used to do the following:

- Track individual items

- Track boxes of products, cages of products and pallets

- Track containers with multiple loads

- Locate equipment within a building

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

RFID devices have a 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.

RFID operating rage depends on the radio frequency used, receiver capability and the environment. Some tags are only readable from under 1m, others can have a 100m range.

RFID tags and labels are very specific to the type of material and size of your assets. For example, metal will deactivate the RFID antenna and the tag will not transmit at all. Using RFID on metal requires a special type of tag with an RFID block to prevent interference with the antenna. Liquid products can also affect the reliability of the RFID signal. To use RFID tags in specific environ-ments, some technologies are needed to support them.

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

The purposes of stores and warehouses are:

1. Maximum use of space.

2. Ready access to all items.

3. Efficient movement of goods.

4. Effective utilization of labour & equipment’s

5. Maximum protection of items

6. Good-house-keeping.

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

Enterprise resource planning (ERP) is the integrated management of main business processes, often in real time and mediated by software and technology. ERP provides an integrated and con-tinuously updated view of core business processes using common databases maintained by a data-base management system. ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across various departments (manufacturing, purchasing, sales, accounting, etc.) that provide the data. ERP facilitates information flow between all business functions and manages connections to outside stakeholders.

Manufacturing resource planning (MRP II) is defined as a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning, and has a simulation capability to answer "what-if" questions and extension of closed-loop MRP. This is not exclusively a software function, but the management of people skills, requiring a dedication to database accuracy, and sufficient computer resources. It is a total company management concept for using human and company resources more productively.

A master production schedule (MPS) is a plan for individual commodities to be produced in each time period such as production, staffing, inventory, etc. It is usually linked to manufacturing where the plan indicates when and how much of each product will be demanded. This plan quantifies significant processes, parts, and other resources in order to optimize production, to identify bottlenecks, and to anticipate needs and completed goods. Since a MPS drives much factory activity, its accuracy and viability dramatically affect profitability.

Procure-to-pay (P2P) is a term used in the software industry to designate a specific subdivision of the procurement process. The procure-to-pay systems enable the integration of the purchasing department with the accounts payable (AP) department. Some of the largest players of the software industry agree on a common definition of procure-to-pay, linking the procurement process and financial department.

Explanation

Economic order quantity (EOQ) model is the method that provides the company with an order quantity. This order quantity figure is where the record holding costs and ordering costs are mini-mized. By using this model, the companies can minimize the costs associated with the ordering and inventory holding. In 1913, Ford W. Harris developed this formula whereas R. H. Wilson is given credit for the application and in-depth analysis on this model.

If the economic order quantity model is applied, the following assumptions should be met:

- The rate of demand is constant, and total demand is known in advance.

- The ordering cost is constant.

- The unit price of inventory is constant, i.e., no discount is applied depending on order quantity.

- Delivery time is constant.

- Replacement of defective units is instantaneous.

- There is no safety stock level, i.e., the minimum stock level is zero.

- Restocking is made by the whole batch.

Because the demand and lead time are constant, no stockout events can occur.

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.

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.

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"

Explanation

MRP I was some of the first business software to be widely adopted during the 1970s. Manufacturers sought these systems in order to improve efficiency and accuracy when it came to basic processes such as production scheduling and inventory management.

By the 1980s, manufacturers realized they needed software that could also tie into their accounting systems and forecast inventory requirements. Enter MRP II, which included these integrations in addition to all the capabilities offered by MRP I. Enterprise resource planning (ERP) software features—which we’ll cover later on—are included in the following table for comparison.

Explanation

The normal breakdown in a manufacturing organisation would be raw materials, components, work in progress and finished goods.

Following are the different types of inventory:

Raw materials are the basic materials that a manufacturing company buys from its suppliers, and that is used by the former to convert them into the final products by applying a set of manufacturing processes. For example, aluminum scrap is the raw material for a company that produces aluminum ingots. Flour is the raw material for a company that produces bread or pizza. Similarly, metal parts and ingots are the raw materials bought by a company that manufactures cars, and crude oil is the raw material for an oil refinery.

Work in progress inventory can also be called semi-finished goods. They are the raw materials that have been taken out of the raw materials store and are now undergoing the process of their conversion into the final products. These are the partly processed raw materials lying on the production floor. And they have also not reached the stage where they have been converted into the final product.

Finished goods are indeed the final products obtained after the application of the manufacturing processes on the raw materials and the semi-finished goods discussed above in the article. They are saleable, and their sale contributes fully to the revenue from the core operations of the company.
