Two alternative designs have been proposed for processing customers in a service center. To compare the performance
Question:
Two alternative designs have been proposed for processing customers in a service center. To compare the performance of the two alternative system designs, we generated 10 days of customer traffic, where a day's traffic consists of a new simulated sequence of customer arrival times and the associated service times (in other words, 10 independent replications). For day 1 of simulated operation, we ran the traffic through the system operating under design A to compute the average time in system for all the customers processed on that day/replication. Day I's traffic is also run through the system operating under design B to compute the average time in system for all the customers processed on that day/replication. The process was repeated for all 10 days of simulated traffic, yielding average time in system (in minutes) for all the customers processed on each day as follows:
