- An online footwear firm Shoe-n-co has four regional warehouses. Demand at each warehouse is normally distributed with a mean of 10,000 per week and a standard deviation of 2,000. Annual holding cost is 25%, and each unit of Prancs rubber shoes costs the company $10. Each order incurs an ordering cost of $1,000 (primarily from fixed transportation cost), and lead time is 1 week. The company wants the probability of stocking out to be no more than 5%. Assume 50 working weeks per year. Suppose that Shoe-n-co follows a periodic review policy with a review period of 2 weeks. Recall that the firm has four regional warehouses with demand at each warehouse that is normally distributed with a mean of 10,000 per week and a standard deviation of 2,000. Further, annual holding cost is 25%, and each unit of Prancs rubber shoes costs the company $10. Replenishment lead time is 1 week. The company wants a service level of 95%.

- Weekly demand for printers at a store is normally distributed with a mean of 250 and a standard deviation of 96. The store manager continuously monitors inventory and currently orders 14400 printers each time the inventory drops to 1,000printers.

The forecasted demand for the coming year for the 40GB HDD is 3,000 units. The company incurs a high ordering cost of $225 per order. The average annual inventory holding cost is estimated to be 25% of the item cost and a safety stock of 25 HDDs is maintained. The company operates for 300 days a year. However, Micron wants to drastically increase prices of HDDs which is not acceptable to Metaverse. The purchase officer of Metaverse has identified another supplier Minnesota Data Products.

- The Corner Drug Store fills prescriptions for a popular children’s antibiotic, amoxicillin. The daily demand for amoxicillin is normally distributed, with a mean of 200 ounces and a standard deviation of 80 ounces. The vendor for the pharmaceutical firm that supplies the drug calls the drugstore pharmacist every 30 days to check the inventory of amoxicillin. During a call, the druggist indicated that the store had 60 ounces of the antibiotic in stock. The lead time to receive an order is 4 days.

The distributor charges $20 per pack of 20 respirators and $10 for a pack of 25 gloves. The distributor offered the healthcare facility the following plan: whenever the medical facility places a single order for both N95 respirators and gloves, the distributor will package one pack of respirators together with two packs of gloves to minimize shipping volume. The remainder of the order of gloves will be sent in the second shipment (without any extra shipping cost), which will be timed so that the healthcare facility receives the second shipment just before it runs out of gloves inventory. The shortages are not allowed. The fixed cost of placing an order is $10 and the holding cost rate is a 20% annual interest rate (assume 365 days per year).
