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，
: Z, K) Z1 [* I' u6 H" A  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.
9 s: \3 f6 W. D4 S  Loads are processed by each operator for the following time:
) t( C0 F4 h% d' g4 r  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 P( O* F( ^, m+ w% B  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.
$ t3 E- T& L0 J2 F* e  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 E) F) h7 ?$ f( }$ C* \6 v- pSend 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.

( i# C: _+ Y0 N, T% l  O+ t8 M问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
5 Z( q- ]( L, Z; B8 p& o3 ymove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
$ R1 P/ X+ I4 v9 F
" D5 H$ [4 n+ }' d* j# ^send to P_B
; d1 d3 p4 R2 x( Y. V' x' Fend

P_B and P_C is similar
triangular 30,60,90 min
8 F( R! t( r: Q5 Ju 60,30 min
) H/ U/ X' L0 @4 K- _

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.


# G/ A7 m3 n; `8 A3 oRemember to turn off the animation before you run your model.
