1. What is the optimal number of motors that Phillips's managers should order according to the E0Q model? 2. At what point should managers reorder the motors, assuming that both demand and purchase-order lead time are known with certainty? 3. Now assume that demand can vary during the 2-week purchase-order lead time. The following table shows the probability distribution of various demand levels: Total Demand for Motors for 2 Weeks Probability of Demand (sums to 1) 1,600 0.05 1,800 0.20 2,000 0.50 2,200 0.20 2,400 0.05 If Phillips runs out of stock, it would have to rush order the motors at an additional cost of $5 per mo- tor. How much safety stock should the assembly plant hold? How will this affect the reorder point and reorder quantity?
