The Robotics Manufacturing Company operates an equipment repar business where emengency jobs arrive randorrly at the rate of two jobs per 8 -hour day. The companys repair faolity is a single-server system operated by a repair technician. The service time varies, with a mean repair time of 2.9 hours and a standard deviation of 2.1 hours. The campany's cost of the repair operabion is \\( \\$ 27 \\) per hour. In the economic analysis of the waiting line system, Robotics uses \\( \\$ 37 \\) per hour cost for custamers waiting during the repair process.
