Question

Ashley’s Department Store in Kansas City maintains a successful catalogue sales department in which a clerk takes orders by telephone. If the clerk is occupied on one line, incoming phone calls to the catalogue department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party that has waited the longest is transferred and answered first. Calls come in at a rate of about 12 per hour. The clerk is capable of taking an order in an average of 4 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. The clerk is paid $10 per hour, but because of lost goodwill and sales, Ashley’s loses about $50 per hour of customer time spent waiting for the clerk to take an order. a)What is the suitable method to solve this problem?
