刚刚开始学auto mod,这道题目搞不明白，希望大家看看 题目是这样的，
) Z' y0 J, {# C  F  Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.
; M7 ]& r% {, j" I0 P' D  Loads are processed by each operator for the following time:
; s! {0 {! z; U! o; k7 ]$ p! r' j  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 i  G7 A8 D. S0 H" U, h5 J+ J  Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
1 {3 A% z5 }( f; S! M# c, h  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.
