All of the following are disadvantages of ERP, except ____, which is an advantage.

D. there is a clearly identifiable parent

Demand for a given item is said to be dependent if:

C. 13

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.

D. 20

Each X requires 2 of component Y and 1 of part W. Each Y requires 10 of Z. Each W requires 3 of Q and 2 of R. Lead times are X = 1 week, Y = 1 week, W = 2 weeks, R = 1 week, Z = 3 weeks, and Q = 3 weeks. The following bill of material reflects the preceding information. The eventual quantity of Z is ____.

A. true

Each X requires 2 of component Y and 1 of part W. Each Y requires 10 of Z. Each W requires 3 of Q and 2 of R. Lead times are X = 1 week, Y = 1 week, W = 2 weeks, R = 1 week, Z = 3 weeks, and Q = 3 weeks. The following time schedule diagram corresponds correctly to the above information.

C. 600

Four A washers, Five B washers, Two C washers, and a D bolt are required to make one Grill parts kit. If 100 grill part kits are needed then _____ more washers than bolts will be used.

E. 300

Given the following bill of material (refer to practice quiz)... If the demand for product A is 50 units, what will the gross requirement for component E?

A. management's attempt to continually respond to minor changes in production requirements

In MRP, system nervousness is caused by ____.

D. Week 4, 40 As

It is week 1 and there are currently 40 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 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?

D. 4 units should be moved from Tuesday to Monday, 2 units should be moved from Wednesday to Tuesday, 2 units should be moved from Wednesday to Thursday, and 1 unit should be moved from Friday to Thursday.

Jacquie Welkener, operations manager for ABC Technologies, must schedule work for the next five days. Each unit takes 30 minutes to process. Available capacity is 8 hours per day. The production order quantities are 12, 18, 20, 13, and 17 for Monday through Friday, respectively. What should be the production plan for load smoothing? (Hint: complete the worksheet below. Units can be moved either one day before or one day after).

D. side braces

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 always available from the small parts supply store. (See corresponding Bill of Material (BOM) below. Numbers in parentheses represent the number of components of that kind required for each A-frame.) Item C most likely represents ____ .

Fasteners are always available from the small parts supply store. See corresponding Bill of Material (BOM) below. Consider the following material requirement planning table. Cell Y most likely represents ____ .

D. Economic Order Quantity (EOQ)

There are three important lot-sizing algorithms used in MRP. They are "lot-for-lot", "part period balancing" and Economic Order Quantity (EOQ). The table below lists them as A, B and C, along with their advantages and disadvantages. The algorithm that best applies to row B above would be ___.

A. lot-for-lot

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

A. 6240

Zum-zum Inc., an outfit that produces birthday celebration gadgets, is trying to implement an MRP along with an order sizing method which minimizes costs. Setup cost is $200 for each order and holding cost is $2/period. If each period is 1 week, gross requirements are 270 units per 10 weeks, and there are 6 planned order releases for every 10 weeks, then the cost of the orders for an entire year is $____, using the lot-for-lot method. Assume that lot-for-lot is computed as though the usage will occur continually throughout the year.
