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,
" D) ]$ o# \3 a' G, y. {' h6 @ 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.
0 q" P6 |% b" U* \$ B, m Loads are processed by each operator for the following time: S* ~9 O# D% [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ f8 e$ P3 [* y5 }& i$ G
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.
( m# G1 u) i/ } F Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 W+ k/ y4 D: Y+ W. w* ^0 BSend 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.

问题:

不胜感激! |
