1. Suppose we are considering the question of how much capacity to build in the face of uncertain demand. Assume that the cost is $20 per unit of lost sales due to insufficient capacity. Also assume that there is a cost of $7 for each unit of capacity built. The probability of various demand levels is as follows: Demand-X Units 0 1 2 3 4 5 6 7 Probability of X .05 .10 .15 .20 .20 .15 .10 .05 a. How many units of capacity should be built to minimize the total cost of providing capacity plus lost sales? b. State a general rule regarding the amount of capacity to build. c. What principle does this problem illustrate?
