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:
4 `* C( @* ?& G( b% {; k% E" @7 b  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 z& V, j, d- N" d8 d  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.
  r- D0 x, l9 w( d# u& r8 ]; |  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; Q0 }' S& l2 r' 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.
9 u* [% o! d7 j, N/ c$ p1 O8 G
4 _3 @$ |* Y- _, 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
! \1 }2 k! l" W9 Vmove into Q_wait /*Capacity is infinte*/
6 z) G0 F: V2 @6 t5 mmove into Q_process /*Single capacity*/
) \8 ]8 }3 _. f9 f* b( A4 O. ?

: L' e8 j/ ?, |6 g# H2 C* s
5 k& F" H& {, s6 w8 esend to P_B
end

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

; m! {" T$ S; W, g4 Z7 j0 ?
/ K" h4 l1 j7 u2 q$ @% W5 Yin 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.
