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,
4 k& p& {) r6 I r" l* N2 o9 [( G 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.2 }& P7 H% U4 i
Loads are processed by each operator for the following time:
0 N* R/ ^2 ?! P( u9 r Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 F8 K7 l* R* Y6 x9 |+ N" n; T 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.
! o, @7 Z$ N: I9 F/ p+ ~* G Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ i% N9 r- ?* h3 l! H
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:
