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，
  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.
  Loads are processed by each operator for the following time:
, y6 B8 h0 u% l# r9 P; W7 S4 R  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.
# d6 _7 K# {  R( q3 `' A  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：
: B4 M! b6 F( [% P9 VAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
2 O7 Q& m" ~* S6 P" vmove into Q_wait /*Capacity is infinte*/
7 G$ C* P! T; z- Cmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
  p8 G$ H1 z+ x$ ^' @$ p1 |7 k

P_B and P_C is similar

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

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