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，9 N1 J4 p6 K/ w, D5 u
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./ `+ t4 V) E( X4 o. ^, T$ j
Loads are processed by each operator for the following time:5 w" E4 x$ F1 S
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 t, W9 g) u1 t) w: T5 R 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.9 v) T$ @, N- R" c
Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ f* S+ u( ~6 ?# h4 P+ {
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.

问题：
