Finally consider a 2 server system. Assume that people enter the queue only if both servers are busy and that if both servers are not busy an arriving customer will go to server 1. Assume that arrival and service times have an exponential distribution.

1. Simulate the arrival times of 10 customers with an arrival rate of l=1.5 customers per minute. Simulate their service times if the mean service time is one minute. Enter these values in the table below.

2. Complete the table below assuming that there is initially no queue. Server is coded as 1 or 2.

1. 
   

	Inter-arrival time	Service time	Arrival time	Server	Service begins	Service ends	Waiting time in queue
