Operations research: Queuing theory using TORA
Kleen All is a service company that performs a variety of odd jobs, such as yard work, tree pruning, and house painting. The company's 4 employees leave the office with the first assignment of the day. After completing an assignment, the employee calls the office requesting instruction for the next job to be performed. The time to complete an assignment is exponential with a mean of 45 minutes. The travel time between jobs is exponential, with a mean of 20 minutes.
(a) Determine the average number of employees who are traveling between jobs
(b) Compute the probability that no employee is on the road.
I need help in how to enter this into TORA, and how to interpret the results.
