2. Consider the loan application office example we modeled in lab classes. There are 4 different processes which are 1) Credit check 2) Preparing the loan covenant 3) Pricing the loan 4) Disbursement of funds Bank manager should decide whether to have specialized serial or generalized parallel workers when processing involves the above tasks. There are 4 workers. The performance measure that bank manager considered is mean response time per customer. In order to find difference between two processing, two models are run with the service times that are generated with independent random numbers, common random numbers with synchronization and common random numbers without synchronization. The average service time for serial and parallel workers models are given below as Model 1 and Model 2 respectively. Replication 1 2 3 4 5 6 7 8 9 10 Average Response Time for Model (minutes) Model 2 CRN Model 2 CRN Model 1 Model 2 IRN w/ Sync w/o Sync. 24.82 17.1 18.63 22.79 44.28 15.67 9.86 24.23 27.3 14.08 16.41 21.24 19.42 11.36 8.90 15.72 34.94 11.71 19.63 22.54 46.71 11.66 17.57 17.78 45.89 17.42 18.32 20.69 31.3 12.58 13. 13 13.77 26.77 9.8 10.46 23.77 22.79 17.15 13.62 23.85 a. Compare the serial and parallel loan application processing using independent sampling and CRN where R-R.-R. Please comment about the results you find. b. Determine how many replications are needed if it is important to detect difference of 4 minutes per customer
