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 O: N1 E+ |. U, n) L
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 y& K8 B/ O2 h# U
Loads are processed by each operator for the following time:' |: ]8 B' i i" x# V2 ? s
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 Q7 N4 ~9 [4 W$ `$ _
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.
- |/ e7 V/ |+ X2 _& P0 f Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
m& ~ P3 m% [, {/ z8 I: SSend 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.
