Exam 14: Material Requirements Planning Mrp and Erp

Each R requires 2 of component S and 1 of part T. The lead time for assembly of R is 3 days. The lead time for the manufacture of S is 5 days. The lead time for the manufacture of T is 10 days. The cumulative lead time for R is __________ days.

Bills of material organized by major subassemblies or by product options are called __________.

In MRP, the number of units projected to be available at the beginning of each time period refers to

The MPS calls for 120 units of Product M. There are currently 30 of Product M on hand. Each M requires 4 of Component N. There are 20 units of N on hand. a. Calculate the net requirements for M. b. Calculate the gross requirements for N. c. Calculate the net requirements for N.

Explain the difference between a gross requirements plan and a net requirements plan.

Wheeled Coach uses __________ as the catalyst for low inventory, high quality, tight schedules, and accurate records.

Given the following bill of material If the demand for product A is 50 units, what will be the gross requirement for component E?

The large parts of a playground A-frame (from which to hang a swing or glider) consist of a ridge pole, four legs, and two side braces. Each pair of legs fastens to the ridge with one fastener set. Each side brace requires two fastener sets for attachment to the legs. Each fastener set includes one zinc-plated bolt, one lock-washer, and one nut. There is one order outstanding, to make 80 frame kits. There are 200 legs in inventory. There are no other large items in inventory, and no scheduled receipts. Fasteners are available from the small parts area. a. Draw the product structure tree b. Calculate the net requirements to fulfill the outstanding order.

How can MRP and JIT be effectively integrated?

Product A is made from 2 Bs and 1 C. Lead times for A, B, and C are 2, 3, and 2 weeks respectively. Currently there are 2 Bs and a 5 Cs on hand, with 5 of each scheduled to arrive at the end of week 1. If 20 As are needed during week 4, can the order be completed (it is the start of week 0 currently)?

A(n) __________ is a bill of material for components, usually assemblies that exist only temporarily; they are never inventoried.

Reduced inventory levels and faster response to market changes are both benefits of MRP.

For the lot-sizing technique known as lot-for-lot to be appropriate

It is week 1 and there are currently 20 As in stock. The MPS calls for 300 As at the start of week 5. If there are scheduled receipts planned for week 3 and week 4 of 120 As each and A has a lead time of 1 week when and how large of an order should be placed to meet the requirement of 300 As?

Consider the following bill of material. Fifty units of Product A are needed. Assuming no on-hand inventory, explode the bill of material.

Demand for a given item is said to be dependent if

Which of the following lot-sizing techniques results in the lowest holding costs?

A master production schedule specifies

Identify the several lot-sizing algorithms used in MRP. Provide at least one advantage and one disadvantage of each.

The MPS calls for 50 units of Product A and 60 of B. There are currently 25 of Product B on hand. Each A requires 2 of Part C; each B requires 5 of C. There are 160 units of C available. The net requirements for C are
