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.
( E9 i! j% R# S# @8 g  Loads are processed by each operator for the following time:
$ D) @  |! L. v0 ]0 a9 ~  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& e% T$ i4 m7 j" O0 G! u  \# _  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.
; S5 d: b$ A" X+ ySend 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.
( i9 D5 i) |( H- _3 X2 K9 T
问题：
# N" i" z& q! X, Z: oAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

use 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
/ [0 k% \5 X5 a5 f5 H, |/ ~% 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.

Remember to turn off the animation before you run your model.
