Case Problem

A new workstation is being designed and a complete analysis is needed as described in this chapter. The workstation operates 168 hours per month. Parts are modeled as arriving according to an exponential distribution with mean 10 minutes. Processing time is uniformly distributed between 6 and 9 minutes. Detractors are as follows. Breakdowns: The average time between breakdowns is 40 hours. Repair time is uniformly distributed between 30 and 150 minutes. Defective parts: Five percent of parts are defective and require rework. Setup and batching: The setup time is 45 minutes. A utilization of 95% is targeted. The best batch size should be determined.

First perform a complete study of the new workstation with no detractors. Use an analytic model as well as a simulation model and experiment. Part lead time is the primary performance measure. Verification and validation evidence for the simulat ion model must be obtained. Second, use a simulation model and experiment to assess the joint effect of all three detractors. Verification and validation evidence should be obtained.

How to do this case study will be described in tutorial style for the simulation environment that you are using in a separate document.
