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,* l2 T/ p$ ?' U- A7 l4 s" f' z
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.2 [1 ?; r0 t5 A$ [
Loads are processed by each operator for the following time:9 }8 K0 R8 Z" n. C, O0 |
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% P0 p L! R1 M9 \2 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.

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.
