I could not attach the queueing template but you can get one online if its needed.

Belton Knitting and Weaving owns 10 identical machines that it uses in the production of colored nylon thread for the textile industry. Machine breakdowns occur following a Poisson distribution with an average of 0.01 breakdowns occurring per operating hour per machine. The company loses $1000 each hour a machine is out of commission. The company employs one technician to fix these machines when they break down. Service times to repair the machines are exponentially distributed with an average of 8 hours per repair. Thus, service is performed at a rate of 1/8 machines per hour.

Management wants to analyze what impact adding more service technicians would have on the average length of time a machine is out of commission. Service technicians are paid $30 per hour.

How many technicians should management have to minimize the total hourly cost of technicans and out-of-commission machines?
