If you stock out, you'll face a $25/jar loss of goodwill. Placing an order costs $50, and money that is tied up in capital is assumed to have a 20% interest rate for calculating holding costs. During the 6-mo replenishment time, he sells ~100 jars, but with substantial variation. Estimates are a standard deviation of demand during each 6-mo period of 25 jars. Assume demand is described by a normal distribution. How should the Jam be ordered?arrow_forwardA newspaper boy is trying to perfect his business in order to maximize the money he can save for a new car.

- HAL Ltd. produces a line of high-capacity disk drives for computers. The housings for the drives are produced in Hamilton, Ontario at a rate of 250 housings per month, and shipped to the main plant in Toronto. The housings cost HAL $100 each to produce, and the setup cost for beginning a production run is $500. HAL uses the drive housings at a fairly steady rate of 1400 per year. Assume an annual interest rate of 25% for determining the holding cost. What is the optimal number of housings for HAL to produce in each production run? For the optimal production size, what proportion of each production cycle consists of uptime and what proportion consists of downtime?
