Master of Engineering Management Program MEM506 (Simulation HW3) Multiple Server System Simulation You are an engineering manager in charge of a service center where customers arrive to the center with an arrival rate 2 = 24 customer/hr. As shown in below figure, the service center has a single queue and 3 parallel service stations each with a service rate u= 10 customer/hr. Both inter-arrival and service times are exponentially distributed. Server 1 Arrival Queue Server 2 Build an ARENA simulation model of the service center Name the ARENA model with your name Show a screen shot of details of each model element (Create, Process, etc.) and include your name in the name of these elements. - Show the complete model picture. Run the model for 40 hours (one week) of operation and obtain results report (replications are 5 and replication time is 8 hours). Study and understand all the elements of the simulation report and include the report of simulation results in the appendix. - Use the simulation results to estimate the averages of same 5 KPIs. Compare QM to ARENA simulation results and show differences (Use a table to compare results). What can you do to improve the accuracy of ARENA simulation results? Show the improved results after action taken. - Use ARENA to sketch one server utilization with run time (40 hrs), what do you conclude
