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 T8 Y) b( V5 d9 }; 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.* r4 y5 Z. i: H8 e0 S' `7 H
Loads are processed by each operator for the following time:
$ a s8 \, V$ t) A2 W8 S5 l Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 `. f2 S& J! X2 C 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.2 f# G0 c0 Q' d
Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ b# x% u3 R/ A7 l7 M2 Z
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.
