3. Consider Model 3-1. Instead of having a single source of parts, there are three sources of arrival, one for each of three different kinds of parts that arrive: Blue, Green and Red. For each color of arriving part, interarrival times are exponentially distributed with a mean of 15 minutes. Processing times at the drilling center are the same as in Model 3-1 and are the same regardless of the color of the part. Run the simulation for 480 minutes and compute the performance measures: average total time in the system and the maximum, average waiting time in queue and the maximum, total production, queue length and drill press utilization. Collect statistics separately by part color where appropriate. Return to Model 3-1. Add a washing machine to which all parts go immediately after exiting the drilling machine. Processing times for washing are the same as for drilling. Gather all the statistics as before plus the time in queue, queue length and utilization at the washing center. Immediately after washing, there is a pass/fail inspection center that takes a constant 5 minutes to carry out and has an 80% chance of a passing result; queuing is possible at inspection, and the queue is first-in, first- out. All parts exit the system regardless of whether they pass the test. Count the number that fail and the number that pass, and gather statistics on the time in queue, queue length, and utilization at the inspection center. Use Decide flowchart module to incorporate pass/fail. Run the simulation for 480 minutes.
