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,
6 P/ { b( Q6 Y- v/ E% O 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 U& S0 T/ g, @* | Loads are processed by each operator for the following time:
4 b/ Y4 z0 B6 s1 a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ E$ w/ Y7 M' U2 b5 ]/ 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.
/ ]& b X3 x1 W9 j Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: Y; g) }; c# [
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.
