asap!! A manager of an inventory system believes that inventory models are important decision making aids. Even though often using an EOQ policy, the manager never considered a backorder model because of the assumption that backorders were “bad” and should be avoided. However, with upper management’s continued pressure for cost reduction, you have been asked to analyze the economics of a backorder policy for some products that can possibly be backordered. For a specific product with D = 1200 units per year, Co = 160, = 4, and = 25, what is the difference in total annual cost between the EOQ model and the planned shortage or backorder model? If the manager adds constraints that no more than 25% of the units can be backordered and that no customer will have to wait more than 18 days for an order, should the backorder inventory policy be adopted? Assume 300 working days per year.

1. Demand is Normally distributed with a mean of 66 per week and a weekly variance of 3. The ordering cost is $57.5. Lead time is 8 weeks. Shortages cost an estimated $4.14 per unit short to expedite orders to appease customers. The holding cost is $7.06 per week. Estimate the stockout risk if the target service level is 0.22. 2. Demand is Normally distributed with a mean of 43 per week and a weekly variance of 8. The ordering cost is $83.26. Lead time is 4 weeks. Shortages cost an estimated $1.96 per unit short to expedite orders to appease customers. The holding cost is $9.2 per week. Calculate ROP if the target service level is 95%.
