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.
2 r4 P  F4 g5 M2 {" V  Loads are processed by each operator for the following time:
8 N( B8 z; V& u  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.
: u, Z' A- s1 k: W- Y6 |3 f  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ S1 E$ s5 _' j5 s9 I/ BSend 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.
; f4 e# U* J8 K4 t: o8 Q& k; S' j
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
! S( S6 h* d4 I) M2 d+ }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 H4 H3 k+ S- Z5 S% r/ A: U& pend

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min


/ I; z* C, {9 J3 i: A! Ein 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.
