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，
: |, U& w+ h8 z  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.
! V* g7 M: i0 ~  Loads are processed by each operator for the following time:
4 W9 ~) ?0 F. |- P* {7 V+ E  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. H8 X0 l! Z) c/ t1 {  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.
: b4 m- A0 m+ p8 FSend 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.

, @5 S, {/ i: N8 G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*/
1 j1 K2 `8 g" ^. I5 T( a
use R_A for n 60,10 min /*Resource A*/

send to P_B

P_B and P_C is similar

4 S) l- d& _0 W. E! J& a$ FThen 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.
