A waiting-line system that meets the assumptions of M/M/S has λ = 5, μ = 4, and M = 2. For these values, P_o is approximately 0.23077 and L_s is approximately 2.05128. The average time a unit spends in this system A) is approximately 0.1603 B) is approximately 0.2083 C) is approximately 0.4103 D) is approximately 0.8013 E) cannot be calculated because λ is larger than μ

Question

Quizplus · Accepted Answer

The average time a unit spends in the system (W_s) is calculated as L_s / λ. Given L_s = 2.05128 and λ = 5, W_s = 2.05128 / 5 = 0.410256, which is approximately 0.4103.
