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,& e( w7 o8 a& b$ D. c
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.
4 Q" y# @9 z5 E9 K Loads are processed by each operator for the following time:/ Q. F' n& T5 M1 i6 \
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 \! ]! G8 [6 C& w1 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, y ~! _7 d Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 a: n' T5 A4 d
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.
