ARENA RUN FOR 40 hrs

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 1 = 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 As an Engineering Manager of the service center, you decided to use the following five Key Performance Indicators (KPIs) to measure system performance: 1. Avg, customer waiting time 2. Avg. time a customer spends in the service center 3. Avg. number of customers waiting in the queue 4. Avg. number of customers in the service center 5. Avg. server utilization
