A waiting-line system that meets the assumptions of M/M/S has λ = 5, μ = 4, and M = 2. For these values, Pₒ is approximately 0.23077 and Ls 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 (Ws) is calculated as Ls/λ. Given Ls = 2.05128 and λ = 5, Ws = 2.05128 / 5 = 0.4103.
