Question: A factory s planer department has had a difficult time keeping
A factory’s planer department has had a difficult time keeping up with its workload, which has seriously disrupted the production schedule for subsequent operations. At times, the work pours in and a big backlog builds up. Then there might be a long pause when not much comes in, so the planers stand idle part of the time. Three separate proposals have been made to relive the bottleneck in the planer department: (1) obtain one additional planer, (2) eliminate the variability of the interarrival times of the jobs, and (3) reduce the variability of the time required to perform the jobs. Any one or any combination of these proposals can be adopted. With the help of the Queueing Simulator, simulation is to be used to determine what should be done so as to minimize the expected total cost per hour.
