The production manager at Aldershot Manufacturing wishes to develop a materials requirements plan for producing chairs over an 8 week period. She estimates that the lead time between releasing an order to the shop floor and producing a finished chair is 2 weeks. The company currently has 200 chairs in stock and no safety stock (safety stock is stock held in reserve to meet customer demand if necessary). The forecast customer demand is for 125 chairs in week 1,35 in week 2,35 in week 3 , 100 in week 4,90 in week 6 , and 45 in week 8. Requirements: 1) Make an MRP L4L rule. 2) MRP based on FPR 7-week rule
