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.
! A6 O1 j- m$ ?+ r" [5 O  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.
6 @8 _4 H7 I" m8 q7 {! G  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.
. `2 K6 }9 {: F# [$ S' D) ?  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 z! }4 _0 Q* g! nSend 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 D4 Q" [& d7 n3 h3 W问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
! Y- u$ }/ C# v, `move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

send to P_B
. `4 T0 `% ~. ~end
1 j$ O6 ?; T9 H9 ?- l" J
P_B and P_C is similar
triangular 30,60,90 min
/ E( P/ c- c  ?+ {$ p! L/ Wu 60,30 min


in 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.


1 V) B# \% u& a( Y' cRemember to turn off the animation before you run your model.
