Q3

1 A law office has a walk in policy for those injured in an accident. Two law buddies are just trying to make the office. Currently, the customers arrive at an average of 4 per hour, and the service time average 28min per visit. The coefficients of variation of the inter-arrival times and the service times is random or in other words equal to 1, determine the utilization of the two law buddies.(0.93)

2. determine the average number of customers in the total law office. (14.53)

3. determine the average customer waiting time (190 min)

4. the two buddies law office decides to go to an appointment only model. Thus, all variability in the arrival of customers disappears- in other words CVa goes to 0 and arrival is considered deterministic. The customer still arrives at an average of 4 per hour, and the service time average 28 min per visit and service variability is still random

Determine the utilization of the two law buddies (0.93)

5 . the two buddies law office decides to go to an appointment only model. Thus, all variability in the arrival of customers disappears- in other words CVa goes to 0 and arrival is considered deterministic. The customer still arrives at an average of 4 per hour, and the service time average 28 min per visit and service variability is still random

Determine the average number of customers in the total law office (8.2)
