Answer:

A) Single-server single-phase model (M/M/1).

$\lambda=2.5 \,customers/hour\\\\\mu=6\,customers/hour$

B) The goal is not met, as the average time waiting for service is 5.56 minutes.

C) The new mean service rate is 7.5 customers/hour.

In this case, the average time waiting for service is 4 minutes, so the goal is met.

Explanation:

A) This situation can be modeled as a single-server single-phase model (M/M/1).

The mean arrival rate is 2.5 customers per hour.

$\lambda=2.5 \,customer/h$

The mean service rate is 6 customers per hour, calculated as:

$\mu=\frac{60\, min/h}{10 \,min/customer}=6\, customer/h$

B) The average waiting time for a customer can be expressed as:

$W_q=\frac{\lambda}{\mu}\frac{1}{\mu-\lambda} =\frac{2.5}{6}\frac{1}{6-2.5} =0.417*0.222=0.093\,hours\\\\W_q=0.093\,hours*(60min/h)=5.56 \,min$

The average waiting time is 5.56 minutes, so it is more than the goal of 5 minutes.

C) If the average time spent per customer to 8 minutes, the mean service rate becomes

$\mu=\frac{60\, min/h}{8 \,min/customer}=7.5\, customer/h$

An the average waiting time for the service now becomes:

$W_q=\frac{\lambda}{\mu}\frac{1}{\mu-\lambda} =\frac{2.5}{7.5}\frac{1}{7.5-2.5} =0.333*0.2=0.067\,hours\\\\W_q=0.067\,hours*(60min/h)=4 \,min$

The average time is now 4 minutes, so the goal is achieved.
