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，
% p: w  x2 o* F; M5 }; ]9 d  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.
/ v* @% L& `0 `  ^  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.
9 b5 y0 i0 W2 A! m  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.
) d) \1 h" _$ i  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( H# a+ u( d; ?& x3 R/ 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.

& F, h2 a, J1 \. l问题：
: I) O4 i6 a- `After running the model for 10,000 days, what was the average number of loads in each process?
) u- J. T! e2 J* h* Y8 N$ X! y

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
0 @' o# L( Q% R/ ]. }move into Q_process /*Single capacity*/

2 P) c8 J6 m. ]% o9 j1 y5 Uuse R_A for n 60,10 min /*Resource A*/
' U8 m; s  s' s/ o/ ]% ~7 \
send to P_B
) z# P5 X1 g* O7 F2 _- z. aend

P_B and P_C is similar

8 x7 X4 x$ v% D; ju 60,30 min
8 F, y, _8 B2 I3 d. b  M" U- A3 ^

$ C+ C2 P. |& P; Xin 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.
