Exam 13: Material Requirements Planning Mrp and Erp

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. Construct the time-phased product structure.

"Phantom bills" are bills of material for subassemblies that do not exist in reality.

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

Effective use of MRP and other dependent demand models does NOT require which of the following?

Which of the following best describes a gross material requirements plan?

The minimum record accuracy required for successful MRP is approximately which of the following?

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

An order for 150 units of Product M has been made. There are currently 30 units of Product M on hand. Each M requires 8 units of Component N. There are 200 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.

What do we mean by closed-loop MRP?

Gross material requirements do not take into account the amount of inventory on hand.

Fourteen A washers, five B washers, three C washers, two D bolts, and eight E bolts are required to make one grill parts kit. If 100 grill parts kits are needed, how many more washers will be consumed than bolts?

Closed-loop MRP systems allow production planners to move work between time periods to smooth the load or to at least bring it within capacity.

MRP can be effective only if very accurate lot sizes are calculated in advance.

DRP is a time-phased stock-replenishment plan for all levels of a distribution network.

Consider the following product structure. If the demand for product A is 50 units, how many units of component D will be needed?

What does enterprise resource planning (ERP) allow an organization to do?

It is week 1 and there are currently 20 As in stock. We need 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 2 weeks, when and how large of an order should be placed to meet the requirement of 300 As?

Blockchain software replaces paper-based transaction records with digital-based records to reduce the complexity of what?

Which of the following statements regarding the gross material requirements plan is TRUE?

What are time fences? Why are they used?
