Q: Ricon, Inc. uses an assembly line to produce its office copiers. The final step in the assembly process is quality control inspection. Copiers arrive at the quality inspection area exactly every 90 seconds. The time it takes to perform a quality control inspection follows an exponential distribution, with a mean of 72 seconds. Ricon management is interested in using simulation to determine the average time it takes a copier to complete its quality control inspection. Conduct a simulation for 20 copier arrivals assuming that the system starts empty. Use the Excel random number function to determine the inspection times. Calculate the average time a copier spends in the system based on these 20 arrivals.
