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,
% ]$ ]) H/ D: [" e/ M- N& i 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.
6 ?$ C8 \) Q. Z$ `2 j& g! N5 k) t Loads are processed by each operator for the following time:
# g) i1 W5 _4 X: j0 K" m Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
X2 H' T- I3 B2 w9 K% `. ?$ h 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.
$ { }# K% R6 O Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 }. a3 `6 e6 M+ t6 t
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.
