- A local retailer anticipates an annual demand 15000 units of a product. The retailer allows shortages for that product, and these shortages are backordered at a rate of 1.5 OMR per unit backordered. The cost of ordering is 400 OMR, whereas, the annual holding cost is 1 OMR per unit. The retailer operates 300 days per year.

The ketchup costs $3.00 per bottle and is served only in whole bottles because its taste quickly deteriorates. The restaurant figures that it costs $10.00 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes 3 weeks for an order to arrive. The restaurant operates 50 weeks per year. The restaurant would like to use an inventory system that minimizes inventory cost. The restaurant has figured that the most economical order size or EOQ is approx. 409 (rounding up the decimals). Suppose that things have become uncertain and that customer demand is no more constant. Customer demand is now normally distributed with mean being the same as given in the problem description and standard deviation = 30 units per week. The supply source is still very reliable and as a result the lead time is constant. Find out the safety stock needed to achieve 95% customer service level.

- A company uses a special widget (SP) in its production process. The company uses 100 SP units per month in a fairly uniform production process. Each SP unit costs R30. Due to the stringent controls associated with the ordering of the widget the order cost is R300 per order. The widget requires special handling and refrigeration and the cost of holding inventory is estimated to be R200 per unit year. Which order size would you recommend that the company use? Suppose the supplier of the special widget offers the company a reduced purchase price of R29/widget, but they need to order 100 or more at a time. Would you recommend that the company accept this offer?
