1. You are the operations manager of a firm that uses the continuous review inventory control system. Suppose the firm operates 52 weeks a year and has the following characteristics for its primary item: Demand = 25,000 units/year Ordering cost = $37/order Holding cost = $4/unit/year Lead time = 2 weeks Standard deviation in weekly demand = 100 units What is the economic order quantity (EOQ) for this ifem? (Please round your calculations to the nearest whole number.)

2. You are the operations manager of a firm that uses the continuous review inventory control system. Suppose the firm operates 52 weeks a year and has the following characteristics for its primary item: Demand = 25,000 units/year Ordering cost = $18/order Holding cost = $5/unit/year Lead time = 4 weeks Standard deviation in weekly demand = 85 units What safety stock level provides a 95 percent cycle-service level (z=1.65)? (Please round your calculations to the nearest whole number.)

Suppose the firm operates 252 days a year and has the following characteristics for its primary item: Demand = 25,000 units/year Ordering cost = $39/order Holding cost = $5/unit/year Lead time = 4 days Standard deviation in daily demand = 9 units Service level = 95% (z=1.65) What is the reorder point? (Please round your calculations to the nearest whole number.)

4. You are the operations manager of a firm that uses the continuous review inventory control system. Suppose the firm operates 252 days a year and has the following characteristics for its primary item: Demand = 25,000 units/year Ordering cost = $34/order Holding cost = $1/unit/year Lead time = 4 days Standard deviation in daily demand = 9 units What is the optimal (expected) number of orders (N) per year (to the nearest whole number)?
