A crew of mechanics at the Highway Department garage repair vehicles that break down at an average of λ = 8 vehicles per day (approximately Poisson in nature). The mechanic crew can service an average of μ = 11 vehicles per day with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $300 per day. The cost associated with lost productivity from the breakdown is estimated at $150 per vehicle per day (or any fraction thereof). What is the expected cost of this system?

2. A crew of mechanics at the Highway Department garage repair vehicles that break down at an average of a = 9 vehicles per day (approximately Poisson in nature). The mechanic crew can service an average of u = 12 vehicles per day with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $250 per day. The cost associated with lost productivity from the breakdown is estimated at $200 per vehicle per day (or any...
A crew of mechanics at the Hamilton Highway Department garage repair vehicles that break down at an average of X = 9.6 vehicles per day (approximately Poisson in nature). The mechanic crew can service an average of IA = 11.6 vehicles per day with a repair time distribution that approximates an exponential distribution (the entire crew works on one vehicle at a time). How many vehicles are likely to be waiting for service at any one time? Assume the centre...

Soltan Security is a security company that retains a service crew to repair its vehicles. The vehicle breakdowns occur at a rate of 3 per day, and follow a Poisson process. The crew can service an average of 8 vehicles per day, with a repair time distribution that resembles the exponential distribution. a) What is the utilization rate of the service system? b) What is the average downtime for a vehicle that is broken down? c)How many vehicles are waiting...
Virginia's Ron McPherson Electronics Corporation retains a service crew to repair machine breakdowns that occur on an average of λ 3 per 8-hour workday (approximately Poisson in nature).

The parts department of a large automobile dealership has a counter used exclusively for mechanics’ requests for parts. The time between requests can be modeled by a negative exponential distribution that has a mean of five minutes. A clerk can handle requests at a rate of 15 per hour, and this can be modeled by a Poisson distribution that has a mean of 15. Suppose there are two clerks at the counter. On average, how many mechanics would be at...
(Overnight) Michael McBryan, an experienced auto mechanic, opens his own automotive repair business, Overnight Auto Service. A distinctive feature of Overnight's business is that all repair work is done at night. This strategy offers customers the convenience of dropping off their cars in the evening and picking them up the following morning. Operating at night also enables Overnight to minimize its labor costs. Instead of hiring full-time employees, Overnight offers part-time work to mechanics who already have day jobs at...
