Obsolescence is the loss of value or usefulness of an item due to changes in technology, fashion, customer preferences, or other factors. Obsolescence is considered a carrying cost, because it is an expense associated with holding inventory over a period of time1. Carrying costs are the various costs a business pays for holding inventory in stock, such as warehousing, insurance, taxes, depreciation, and opportunity costs2. Obsolescence can increase the carrying costs of inventory,because it can reduce the demand and sales potential of the item, and may require the item to be written off or sold at a lower price3.
The other options are not considered carrying costs, because they are not related to holding inventory in stock. Setup is the cost of preparing a machine or a process for production. Transportation is the cost of moving goods from one place to another. Scrap rate is the percentage of defective or unusable units produced in a process. These costs are more related to production or distribution activities than inventory holding activities.
Question 2
An increase in the scrap allowance in an assembled item will result in which of the following consequences?
Options:
A.
An increase in the component items’ cost
B.
A change in the bill ofmaterials’(BOM) quantity per assembled item
C.
Replanning of the component items in material requirements planning (MRP)
D.
An increase in the assembled item's planned lead time
Answer:
C
Explanation:
Explanation:
Scrap allowance is a percentage or quantity of material that is expected to be lost or wasted during the production process. Scrap allowance is usually applied to the component items in a bill of materials (BOM), which is a document that lists the materials, quantities, and relationships required to produce an end item. An increase in the scrap allowance in an assembled item will result in replanning of the component items in material requirements planning (MRP), which is a system that calculates the timing and quantity of materials and resources needed to meet the production plan. Replanning of the component items in MRP means that the system will adjust the planned order releases, order quantities, and due dates of the component items to account for the increased scrap allowance. Replanning of the component items in MRP will ensure that enough material is available to meet the demand for the assembled item, and to avoid shortages or excess inventory.

Question 3
Which of the following is an example of implosion in distribution requirements planning (DRP)?
Options:
A.
Gathering information from several field locations and aggregating it at the manufacturing facility
B.
Gathering information from the manufacturing facility and distributing it to the field locations
C.
Redistributing inventory from several warehouses to one central warehouse N
D.
Redistributing inventory from several field locations and centralizing it at the manufacturing facility
Answer:
A
Explanation:
Explanation:
Implosion in distribution requirements planning (DRP) is the process of calculating the gross requirements for a supplying location based on the net requirements of its customers or demand sources1. Implosion is the opposite of explosion, which is the process of calculating the net requirements for a demand source based on the gross requirements of its customers or demand sources2. Implosion and explosion are used to synchronize the supply and demand across different levels of the distribution network3.
An example of implosion in DRP is gathering information from several field locations and aggregating it at the manufacturing facility. This example shows how the manufacturing facility, which is the supplying location, can determine its gross requirements by adding up the net requirements of its field locations, which are its customers or demand sources. This way, the manufacturing facility can plan its production and inventory levels to meet the demand from the field locations.
