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.
" y' s$ A7 P% K6 o0 D3 V  Loads are processed by each operator for the following time:
4 B/ V  M% W" k3 O  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 I/ h6 A! s- y) 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.

问题：
4 r( @. Q$ [2 T- {After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
# s1 V+ K/ P  G7 O: `$ V. emove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
5 Y* X$ O/ l  |
use R_A for n 60,10 min /*Resource A*/

send to P_B
: o2 F: y  G. c9 Uend

P_B and P_C is similar
$ d2 C2 u7 U- z: S, `6 T! |* Ntriangular 30,60,90 min
u 60,30 min
& s+ g& |5 r9 U4 m
; M$ B/ L4 w2 Y2 F% t
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.
