Problem 7: It is week 1 and there are currently 20 bikes in stock (i.e., 20 units as on hand inventory in week 1). The MPS says that we need 340 bikes in week 5 and 0 bikes for each of weeks 1, 2, 3, and 4. You do NOT need to show your calculation steps. There is NO partial credits for any mistake (i.e., each answer is either right or wrong). Q.7.A. If there are only scheduled receipts planned for week 3 and week 4 of 120 bikes each; and this bike has a lead time of 1 week, when and how large of an order should be placed (i.e., planned order release) to meet the gross requirement of 340 bikes in week 5? Assume that SS = 5, BI = 0, and Q = 15. Q.7.B. If there are only scheduled receipts planned for week 3 and week 4 of 120 bikes each; and this bike has a lead time of 1 week, when and how large of an order should be placed (i.e., planned order release) to meet the gross requirement of 340 bikes in week 5? Assume that SS = 0, BI = 0, and Q = LFL.
