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.
$ ?5 W% |5 T, q  Loads are processed by each operator for the following time:
" V& E2 s: [: l" X. c& r6 }  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.
5 o7 L7 S; |$ p7 c+ p1 T$ s7 @, v  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：
( l4 J0 q8 l8 u) X1 n9 \7 UAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
, u1 H4 n! r4 N" C" ]# I2 @move into Q_process /*Single capacity*/
7 q3 f" T. X. w: A+ t7 e
  a8 d7 `& q+ D( x5 S/ Luse R_A for n 60,10 min /*Resource A*/

send to P_B
end

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


( P. i( x" H' |2 z2 _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.

  c2 O( y$ v+ J
Remember to turn off the animation before you run your model.
