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:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ A1 r& s7 z! O# B; c; W$ i  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.
* W; N2 A# W4 F: j0 [0 ]. y; o  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：
5 Z  K0 Z2 {) D: OAfter 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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

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

& a- @0 _9 W+ m8 F$ D, Zsend to P_B
end
& i( {& C1 [3 {4 O9 V, c1 b
P_B and P_C is similar
2 P) V0 i3 ?4 f5 ~$ r* Wtriangular 30,60,90 min
u 60,30 min


in P_C, you need to send to die.
# r) r: b1 N# E; w
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
1 R2 A2 o6 ^% L# g& |- }7 d( z! O

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