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,: l: i- E& K, ]" e' B% {
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.
4 G0 A: ~. S. r. U5 l9 e* u Loads are processed by each operator for the following time:
0 C7 v" @0 a- d$ i- D' \% L Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. @& Z! K& l! a- } x, 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.3 O! J3 h# `4 w- D R/ n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 h) S* | i+ L( _2 [6 t) N
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.
