3.30. Using the approximation of Eq. 3.19, compute the cycle time in an M/G/1 system for three systems with the same arrival rates of = 4 and service times E[Ts] = 0.2, but different squared coefficients of variation (C2[Ts] = 1/2,1,2). Ca is not arrival rate ,Cs is not service rate . C^2a and C^2s are the squared coefficients of variation for the inter-arrival distribution and the service time distribution, respectively. Eq. 3.19: CTs(G/G/1) (Ca^2 + Cs^2) / 2*(u /1-u)*E[Ts] + E[Ts]
