A multiple channel queuing system with a Poisson arrival rate and exponential service time has an average arrival rate of 4 customers per hour and an average service time of 18 minutes per customer. A single channel queuing system has an average service time of 16 minutes per customer, which is exponentially distributed. The manager is thinking of converting to a system with a constant service time of 16 minutes. The arrival rate will remain the same. Customers are processed in order of arrival.
Customers wait in a single line.
All of the above are assumptions. A queuing system has four crews with three members each. A multiple channel system has customers arriving at an average rate of five per hour and an average service time of forty minutes.
