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,. d4 o$ g+ T! J 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.* D4 x' |. e' R, K \4 b
Loads are processed by each operator for the following time:4 E+ w6 z4 L6 b0 E# V

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.6 q K. @0 w1 V4 Y1 i
