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,8 e+ C9 g* e" P, {) j
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.: T3 A. u) V' H7 _, Y/ K( Z
Loads are processed by each operator for the following time:
' R! `* q1 [2 |; _ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: G& Y3 b# t$ S- p% O ^4 E
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.& y8 A1 ~- d: ?1 W+ o0 w/ \
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* y' A0 A6 [2 H. N: W7 v, g; uSend 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.
