本人初学auto mod,有一道题目希望大家赐教

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，
  j  {7 M* |4 L, ~' N2 y3 J8 d  L  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.
  S- p' m# W& 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.
, C/ Q% C6 K' R  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.
  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.

问题：
. N* q% R! [1 V: H6 S( oAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
5 m8 K% G% q9 B9 v9 {6 }2 n" Jmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
$ ]9 N5 W4 {+ G- Z( [) m
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar

in P_C, you need to send to die.
- y- t+ O' k/ b7 `
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
4 ?) g7 v6 s+ g- i: U9 ?

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