b. Why is it important to be able to assume that demand will be level during each six-month period?
c. If the vendor is willing to offer a discount of $10 per order for ordering in multiples of 50 units (e.g., 50, 100, 150), would you advise the manager to take advantage of the offer in either period? If so, what order size would you recommend?

The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days.
If the order size was 1,000 kilograms of resin, what would be the average inventory level?

- A manager of a firm receives a forecast of a component for the next year. The usage rate of the component is projected to be normal 1250 units per month with a standard deviation of 5 units per day. The lead time to procure a lot is 6 days. The annual holding cost is $3 per unit, and it costs an estimated $64 to process an order. The firm operates 25 days per month. a. Determine an order size that will minimize the sum of ordering and carrying costs. b. Calculate the annual minimum inventory cost. c. What amount of safety stock would provide a stock-out risk of 3 percent? d.

- 1. Forrest and Dan make boxes of chocolates for which the demand is uncertain. Forrest says, "That's life." On the other hand, Dan believes that some demand patterns exist that could be useful for planning the purchase of sugar, chocolate, and shrimp. Forrest insists on placing a surprise chocolate-covered shrimp in some boxes so that "You never know what you'll get." Quarterly demand (in boxes of chocolates) for the last three years is shown in the table below: b. If the expected sales for chocolates are 14,400 cases for year 4, use the multiplicative seasonal method to prepare a forecast for each quarter of the year. (Round all intermediate calculations to two decimal places.) The first quarter forecast is what? boxes of chocolates.

Mr. Stone is currently replenishing the vending machine to its full capacity of 1000 cans every Monday morning, i.e., he uses a Base Stock System with review period P=7 days. Based on a recent demand analysis by Mr. Stone, the daily demand follows approximately a normal distribution with mean 140 and a standard derivation of 50. ä (a) What is the current stockout probability between two consecutive replenishment periods? ä (b) Mr. Stone is considering a more frequent replenishment policy to improve the cycle-service level to at most 1% stockout probability. To achieve this, what would be the maximum length (in days) of the replenishment periods?arrow_forward
