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,' P9 h& S: {) ]" {% _+ u# H6 i1 W% y
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.% Q# W# U9 g% p+ @
Loads are processed by each operator for the following time:
5 a+ J2 J6 R1 E- ? Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' B7 ~' u- M$ }: u1 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.# ?6 l3 {$ d" X% }1 b* P& l
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
