A Waiting-Line System That Meets the Assumptions of M/M/S Has

Multiple Choice

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
