- Consider the product structure diagram given. Assume that the MPS for the end item for weeks 10 through 17 isWeek 10 11 12 13 14 15 16 17Net requirements 100 100 40 40 100 200 200 200Assume that lot-for-lot scheduling is used throughout. Also assume that there is no entering inventory in period 10 and no scheduled receipts. For the example given above, assume that the setup cost for both components A and B is $100 and that the holding costs are respectively $0.15 and $0.25 per component per week. Using the Silver–Meal algorithm, determine the planned order releases for both components A and B and the resulting gross requirements schedules for components C, D, and E.arrow_forwardAssume you are the manager of Assembly Inc., you have just received an order for 40 units of an industrial robot, which is to be delivered at the start of week 7 of your schedule. Using the following information, determine the timing of subassembly G, given the subassembly G must be ordered in multiples of 80 units & all other components are ordered lot for lot.

Which of the following statements about lot-sizing rules for MRP is true? a) The periodic order quantity (POQ) rule generates a higher level of average inventory since it creates inventory remnants. b) FOQ is a dynamic lot-sizing rule which reduces the amount of inventory, by doing a better job of matching the order quantity to the projected on-hand inventory quantity. c) The lot for lot rule minimizes inventory investment but maximizes the number of orders placed. d) In general, static lot-sizing rules introduce greater instability into the production process 2. 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 costs 3.
