14.) A part structure, lead time (weeks), and on-hand quantities for product A are shown in Figure 14. From the information shown, generate:
a) An indented bell of material for product A.
b) Net requirements for each part to produce 10 As in week 8 using lot-for-lot.
Figure 14:
In each of the following, name the term defined or answer the question. Answers are listed at the bottom.
1. A term used for a computer system that integrates application programs for the different functions in a firm.
2. The logic used to calculate the needed parts, components, and other materials needed to produce an end item.3. This drives the MRP calculations and is a detailed plan for how we expect to meet demand.
4. Period of time during which a customer has a specified level of opportunity to make changes.
5. This identifies the specific materials used to make each item and the correct quantities of each.6. If an item is used in two places in a bill-of-materials, say level 3 and level 4, what low-level code would be assigned to the item?
Develop a material requirements plan for component H. Lead times for the end item and each component except B are one week. The
lead time for B is three weeks. Sixty units of A are needed at the start of week 8. There are currently 15 units of B on hand and 130 of E
on hand, and 50 units of Hare in production and will be completed by the start of week 2. (Leave no cells blank - be certain to enter
