Simulation Revision Activity:

Consider the queueing network configuration of a manufacturing organisation given below, where all part arrivals to be processed exhibit a Poisson distribution and the processing time are exponentially distributed as shown in the Figure and Table below.

$\backslash$table$[[$Server$,$m$,\backslash$table$[[$Mean Processing Time$/],[$Part $($Minutes$)]]],[$A$,2,0\mathrm{.}40],[$B$,1,0\mathrm{.}20],[$C$,1,0\mathrm{.}30]]$

Determine the below performance metric in terms of the waiting line configuration of this manufacturing system.

a$)$ Server Utilisation

b$)$ Average Waiting time in Queue

c$)$ Average Number in System

d$)$ Average Time in System
