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,3 }' p: }, G$ W2 v- L. T; A
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.
. u. g3 S- T5 M Loads are processed by each operator for the following time:
" {; z: }* U( ^# B+ R1 R6 | Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* Q' A# d1 W/ L3 y$ H$ J, a 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.% K, f* v6 V" l! A0 z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; V, u: o1 z' M9 t& ^' L8 ESend 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.
