1) Consider a (MMI3GDk(oo) queueing system with k-4, an arrival rate 2 -3, and a service rate a) Nicely draw the rate diagram for this queueing system (similar to Figures 9 and 10, page 1065, in b) Explicitly write the system of differential equations for the birth-death process corresponding to μ = 3/2· your textbook). this queueing system (see your class notes). You need to write k+1 differential equations, one for each the states of the system. c) Solve the system of differential equations; assume that at time t-0, the system is full; that is, P(0)-1. Show all your caleulations in detail. You may use MatLab, MathCad, or Excel to d) Explicitly give the solution (function) for Po(), that is, the probability that the system is empty at e) Compute Po(t), Pi(t),.. P(), fort-0.00,0.33,0.67, 1.50, 2.00,3.00, and 4.00. Use the following perform the necessary matrix operations. any time t. tableto present your 067-T results: t-0.00 t 1.50 t- 2.00t 3.00t 4.00 Pdt) P.(t) P:(t) P(t) P(t) P:(t) ft) On the same graph, plot Po() Pi(t), .
