Question

1. The MRP input listing the assemblies, subassemblies, parts, and raw materials needed to produce one unit of finished product is the a. Master Production Schedule b. Inventory record file c. Bill of Materials d. Net requirements chart 2. The gross requirement of a dependent item is computed from the a. gross requirement of the parent items b. c. d. planned order receipt of the parent items. net requirement of the parent items. planned order release of the parent items. 3. A report which shows expected capacity requirements for current, planned, and expected jobs is a a. MRP report b. bill-of-materials report c. inventory status report d. load report 4. In the PERT model, the variance of the project completion time is calculated by a adding the variances of all activities. b. adding the variances of all activities not on the critical path c. adding the variances of all activities on the critical path d. choosing the largest variance that occurs from the pool of individual activity variances 5. In a project network, a. there is always one and only one critical path b. there may be more than one critical path c. there may be no critical path at all 6. A critical activity is an activity where the slack time is a. positive b. negative c. zero d. loose Information for Problem 7-12. Below are the product structure diagrams (BOM) for items X and Y, and the inventory record file for all items. Fill out the MRP tables for all items then answer questions 7-12. Notice that items C, D and E appear in more than one locations. X LT-1 Y, LT-2 B(3), LT-2 D(I), LT-2 C(3), LT-1 D(1), LT-2 C(2), LT-1 D(2), LT-2 E(2), LT-2 E(2), LT-2 Springa 2018 Test 4

Explanation / Answer

1.

C

It is the BOM or bill of material, that gives the details that how much of each sub items will be used to produce one unit of final product.

2.

C

Is the planned order release of the parent item, that tells the gross requirement of the dependent item.

3.

E

It is the lad report.

4.

C

Summing up the variance of each activity under the critical path is termed as variance of the network

5.

B

There can be more than 1 critical path in one network and it is possible.

6.

C

A critical activity has zero slack time. It means that early start and late start time is the same.
