FOR PARTS a AND c, PLEASE CARRY OUT ALL CALCULATIONS TO 5 DECIMAL PLACES. Mr. Cheney owns a large gas station in Vermont. The average and standard deviation of inter-arrival times of cars stopping by for re-fueling is 3 minutes. If all the pumping stations are full, cars will bypass Mr. Cheney’s gas station for one further up the road (which also happens to charge the same price). Currently, Mr. Cheney has 6 pumping stations and on the average, it takes 5 minutes to service a vehicle which has stopped by for refueling. You are required to answer the following questions: a) What percentage of the time will a customer bypass Mr. Cheney’s gas station. b) What is the average number of customers served per hour. c) Assume that it costs Mr. Cheney $ 12.50 in lost profit per customer lost. It is possible to add 3 more pumping stations at an amortized cost of $ 1.50 per hour. Should Mr. Cheney add the additional 3 pumping stations? The appropriate worksheet for this problem is “m-cap units & N-m=0.” a = average interarrrival time p = average service time m = number of capacity units Enter a (average interrarival time) Enter p (average service time) Enter m (number of capacity units) Probability that all m capacity units are busy Effective Utilization per capacity unit Effective Flow Rate per unit time Customers lost per unit time.
