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，
& z! N" G0 l# S3 K. M  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.
8 \3 i* u, N% Z* m( a; u  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* v+ f* \9 M. N  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.
) h4 d3 v) |' z6 F" _* d6 x  Worker_C does the job in a uniformly distributed time between 30 and 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.

begin P_A arriving

move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

send to P_B

P_B and P_C is similar

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