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，
0 N# b+ m. u) {6 O7 e  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.
7 Q4 h1 T/ i9 v* S, Z1 w  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.
  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.
* w7 G% A6 g$ {4 M8 F. s/ Q; C  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.
6 v+ y* k0 _. o) {1 W' K3 Q
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

P_B and P_C is similar

in P_C, you need to send to die.
