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,
7 I. U2 @) l. `$ J1 e- O; S  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.9 V% y- _+ x, w0 Q/ C
  Loads are processed by each operator for the following time:
3 I7 y& }' q9 v( e; _# ^3 Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' E! _& Z/ B- X3 u  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.
* H/ t' c; y& ?5 E  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 B2 f3 Q$ Q, M  _- _# H
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.

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.- M  R4 _$ U6 N# ^6 B$ g4 w

Remember to turn off the animation before you run your model.
