In a P system, the lead time for a box of weed-killer is three weeks and the review period is one week. Demand during the protection interval averages 241 boxes, with a standard deviation of demand during the protection interval of 60 boxes. a. What is the cycle-service level when the target inventory is set at 250 boxes? Refer to the standard normal table as needed. The cycle-service level is 55.96 %. (Enter your response rounded to two decimal places.) b. In the fall season, demand for weed-killer decreases but also becomes more highly variable. Assume that during the fall season, demand during the protection interval is expected to decrease to 180 boxes, but with a standard deviation of demand during the protection interval of 70 boxes. What would be the cycle-service level if management keeps the target inventory level set at 250 boxes? Refer to the standard normal table as needed. The cycle-service level would be %. (Enter your response rounded to two decimal places.) A golf specialty wholesaler operates 50 weeks per year. Management is trying to determine an inventory policy for its 1-irons, which have the following characteristics: > Demand (D) = 2,500 units/year > Demand is normally distributed > Standard deviation of weekly demand = 3 units > Ordering cost = $50/order > Annual holding cost (H) = $6.00/unit > Desired cycle-service level = 92% > Lead time (L) = 4 weeks = Refer to the standard normal table for z-values. a. If the company uses a periodic review system, P should be 4 weeks. (Enter your response rounded to the nearest whole number.) T should be units. (Enter your response rounded to the nearest whole number.) In a Q system, the demand rate for strawberry ice cream is normally distributed, with an average of 305 pints per week. The lead time is 8 weeks. The standard deviation of weekly demand is 16 pints. Refer to the standard normal table for z-values. a. The standard deviation of demand during the 8-week lead time is 45 pints. (Enter your response rounded to the nearest whole number.) b. The average demand during the 8-week lead time is pints. (Enter your response as an integer.)
