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,' _$ V2 ?" D, Z5 N0 e2 _+ G
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.5 Q# X' L# g& c9 u
Loads are processed by each operator for the following time:
3 h$ b! \9 A4 [9 R! M7 t2 _9 g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.

Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 G- W2 g* n9 N; j2 mSend 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.
