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 G& c: [9 P/ E- E- K
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.! {& W' o6 q* P$ h# W4 Y
Loads are processed by each operator for the following time:4 l% I$ D4 f( Q$ {' A- C b
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: j; m ^4 [# d5 V
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.
, n- ]9 j& r5 W7 Q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
B; ~! I1 C( g8 S# T! kSend 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:
