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,1 K9 H1 }( ?2 |/ a; h- E' r; r% Z
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$ r: L& E7 h* a+ ?2 h4 } Loads are processed by each operator for the following time:
1 U( h# `2 `- d: _+ b. Z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 C+ j* c5 y' `% [# I7 o$ 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. W& D( w( D$ |( c
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 X7 `2 D! \: ^! g _. U0 }- f
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.( L* ^! y4 g, p; n( Z! A% w
