Answer & Explanation:Schips Department Store operates a ?eet of 10 trucks. The
trucks arrive at random times throughout the day at the stores truck dock to
be loaded with new deliveries or to have incoming shipments from the regional
warehouse unloaded. Each truck returns to the truck dock for service two times
per 8-hour day. Thus, the arrival rate per truck is 0.25 trucks per hour. The
service rate is 4 trucks per hour. Using the Poisson arrivals and exponential
service times model with a ?nite calling population of 10 trucks, determine the
following operating characteristics: a. The probability no trucks are at the truck dock b. The average number of trucks waiting for
loading/unloading c. The average number of trucks in the truck dock area d. The average waiting time before loading/unloading begins e. The average waiting time in the systemf. What is the hourly
cost of operation if the cost is $50 per hour for each truck and $30 per hour
for the truck dock? g. Consider a two-channel truck dock operation where the
second channel could be operated for an additional $30 per hour. How much would
the average number of trucks waiting for loading/unloading have to be reduced
to make the two-channel truck dock economically feasible?h. Should the company
consider expanding to the two-channel truck dock? Explain.I will send sample excel spreadsheet when problem is accepted.
