Chapter 11, Problem 25P
Figure 11.44 shows the BOMs for two products, A and B. Table 11.12 shows the MPS quantity start date for each one. Table 11.13 contains data from inventory records for items C, D, and E. There are no safety stock requirements for any of the items.
- Determine the material requirements plan for items C, D, and E for the next 8 weeks.
- What specific managerial actions are required in week 1?
- Suppose that a very important customer places an emergency order for a quantity of product A. TO satisfy this order, a new MPS of 200 units of product A is now required in week 5. Determine the changes to the material requirements plan if this order is accepted and note any problems that you detect.

The BOM for product A is shown in Figure 11.45. The MPS forproduct A calls for 120 units to be started in weeks 2, 4, 5, and8. Table 11.14 shows data from the inventory records.a. Develop the material requirements plan for the next8 weeks for each item.b. What specific managerial actions are required in week 1?Make sure you address any specific difficulties youencounter in the inventory records.
Product A is made from components B and C. Item B, inturn, is made from D and E. Item C also is an intermediateitem, made from F and H. Finally, intermediate item E ismade from H and G. Note that item H has two parents. Thefollowing are item lead times:a. What lead time (in weeks) is needed to respond to a cus-tomer order for product A, assuming no existing invento-ries or scheduled receipts?b. What is the customer response time if all purchased items(i.e., D, F, G, and H) are in inventory?c. If you are allowed to keep just one purchased item instock, which one would you choose?
