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:
& ]& o, O8 u* Z( N. [. h  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  S& n+ j: b6 @: v  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.
/ D4 l& {- k( O8 \  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% @! n3 G% k4 rSend 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：
% J  [7 J! P* N. I+ L; YAfter 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
, k7 r) o" f1 M0 B* jmove into Q_wait /*Capacity is infinte*/
6 Z9 A, k1 S9 z& k/ Umove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
, i& b& X9 w) D; o
send to P_B
end

! K1 z% K9 p% ]P_B and P_C is similar
' F; Z! `$ I5 X0 ~7 ytriangular 30,60,90 min

3 S6 I. E4 w. `2 Lin P_C, you need to send to die.

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.
