A computer center has two color printers. Students arrive at a rate of one every 8 ± 2 minutes to use the color printer. They can be interrupted by professors, who arrive at a rate of one every 12 ± 2 minutes. There is one systems analyst who can interrupt anyone, but students are interrupted before professors. The systems analyst spends 6±4 minutes on the color printer and then returns in 20±5 minutes. Professors and students spend 4+2 minutes on the color printer. If a person is interrupted, that person joins the head of the queue and resumes service as soon as possible. a. For such case, explain what kind of queuing rule is being applied! b. If you were asked to improve such case, describe your objectives and explain what performance-measures would you use? c. Following point 1.b.. explain your plan to improve such case.
