Problem 1 (EOQ model with lead times and integer multiple policy): Consider the EOQ model discussed in class with fixed ordering cost K, holding rate cost per unit item per unit of time h, per-unit purchasing cost $C and demand rate d. Let Z(T) be long-run average cost of a zero inventory ordering (ZIO) stationary policy with reorder interval T. (a) Now assume that there is a positive lead time of L > 0 units of time between the moment an order is placed and the moment it actually arrives and can be used. Characterize the optimal policy. (b) Now in contrast to the Power Of Two policy discussed in class, suppose the warehouse’s reorder interval can only be an integer multiple of t. That is, the warehouse can order every t, or 2t, or 3t, and so on. Prove that the optimal reorder interval T* has the following property. There exists an integer m such that T* = mt and √(m − 1/m) ≤ (T^e/T*) ≤ √(m + 1/m), where T^e, the economic reorder interval, is T^e = √(2K/hd). (c) Suppose now that m ≥…
