Problem $3$

Consider the system from the last problem with the following stations:

$$ Station $1$ has $4$ identical clerks with average service time of $15$ minutes per car.

$$ Station $2$ has $8$ identical inspectors with average process time of $25$ minutes per car.

$$ Station $3$ has $12$ mechanics with average mechanical inspection time of $40$ minutes per car.

$1.$ Assume that $16$ cars come every hour on average. Compute the system throughput, cycle time, and

CV squared of the departing cars after mechanical inspection.

$2.$ Assume that $10$ cars come every hour on average. Compute the system throughput, cycle time, and

CV squared of the departing cars after mechanical inspection.
