In the tool and die room of the Dorben Company, the work measurement analyst wishes to determine a standard for the jig boring of holes on a variety of molds. The standard will be used to estimate mold costs only, and it will be based on operator wait time for molds coming from a surface grinding section and on operator machining time. The wait time is based on: a single server, Poisson arrivals, exponential service time, and first come, first-served discipline. A study revealed the average time between arrivals was 58 minutes. The average jig-boring time was 46 minutes. What is the possibility of a delay of a mold at the jig borer? What is the average number of molds in back of the jig borer?
