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,: V0 g2 x# R" S8 U8 N3 v
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.0 x- f+ H2 P" R
Loads are processed by each operator for the following time:
/ A; k, T8 y7 k4 W/ k Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; ?9 p) {# m3 s7 _- F. { 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 g. Y0 l" [ j% Y% f% @- C( S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% N; L6 |% h5 x$ |( q/ XSend 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.0 m" ]5 _9 J# q1 [- H

问题:
