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? Assuming that HAL produces the optimal number of housings in each production run, what is the maximum on-hand inventory level of these housings? What is the annual cost of holding and setup?

1. David and Beth Sheba run a health food store. Their top selling item is called Heavenly Kelp. The annual demand for this is 3200 units, and demand is constant throughout the year. The cost of placing an order is $100, while the holding cost per unit per year is $4. How many orders per year should be placed if they wish to minimize their total cost ? If you want to be eligible for partial credit, give an idea as to how you arrived at that number?
Consider the coffeehouse discussed below. Suppose that its setup cost for ordering was really only $15. Determine the error made in calculating the annual cost of holding and setup incurred as a result of its using the wrong value of K.

The beans are purchased from a local supplier for $2.40 per pound. The coffeehouse estimates that it costs $45 in paperwork and labor to place an order for the coffee, and holding costs are based on a 20 percent annual interest rate.
