Chapter 8, Problem 44AP
Summary Introduction
Interpretation:Discuss the ‘target’ of zero in-process inventory and explain why it is not feasible in spite of the MRP systems in place.
Concept Introduction:
Work in process inventory is supposed to serve the same purpose as the RM and the FG inventory i.e. a buffer against variations in all the related activities/sub-processes. The variation may be on the supply side or the demand side.
MRP is a system for steady demand scenario and aim at planning and
The lot by lot system means the material movement at every process/sub-process is in a lot and not as a single piece.

Work-in-process (WIP) inventory is a term that refers to the inventory of componentsand subassemblies in a manufacturing process. Assuming lot-for-lot scheduling at all levels, theoretically the WIP inventory should be zero. Do you think that this is likely tobe the case in a real manufacturing environment? Discuss the possible reasons for largeWIP inventories occurring even when an MRP system is used
Consider the bill of materials (BOM)
shown below. If inventory consists of 3
units of B, 2 of F, and 2 units of G, how
many units of B must be assembled
to produce 6 units of product A?
(Enter your response as an integer.)

In a MRP problem, A is a MPS item. Every A requires 2 B’s and 3 C’s. Every B requires 5 C’s. All lead times are two periods. All initial inventory values are 0. Use lot-for-lot method for order quantities for all items. What is the low level code (LLC) for B and C?

- The inventory control models are often labeled independent demand models and MRP is often labeled a dependent demand system. What do the terms independent and dependent mean in this context?arrow_forwardIn an MRP problem, A is an MPS item. Every A requires 2 B’s and 3 C’s. Every B requires 5 C’s. All lead times are two periods. Initial inventory values for A is 100, B is 200 and C is 0. Use lot-for-lot method for order quantities for all items. If gross requirement for A is 800 in period 9, what will be the planned order release for B in period 5?arrow_forward1. The underlying logic for level-by-level processing in an MRP system is: a) Each item in a bill of materials must be processed from the bottom up b) Items without safety stock quantities must be processed before items that have safety stocks greater than zero c) Items must be processed in order of increasing lead time d) All parents of an item must be processed before that item is processed. 2. Which one of the following is the most likely example of dependent demand for an MRP controlled item? a) Demand for spare parts b) Demand directly from customers c) Demand from quality control department for destructive testing. d) Demand from MPS 3. Which one of the following is a reason to have small inventories? a) To improve customer service b) To reduce ordering costs c) To reduce equipment setup costs d) To reduce interest expense or opportunity costsarrow_forward
