Consider the single-server variation of the nonpreemptive priorities model presented in Sec. 17.8. Suppose there are three
Question:
(a) Calculate W1, W2, and W3.
(b) Repeat part (a) when using the approximation of applying the general model for nonpreemptive priorities presented in Sec. 17.8 instead. Since this general model assumes that the expected service time is the same for all priority classes, use an expected service time of 0.3 so μ = 3 1/3. Compare the results with those obtained in part (a) and evaluate how good an approximation is provided by making this assumption.
