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:
7 W9 G" [5 r  ]9 I' Q! l1 m  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 `  X; t: m# I4 T  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.
% j) J/ y( b+ i- x! y7 O" MSend 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.
+ ]% U+ W, L/ T
问题：
After 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*/
move into Q_process /*Single capacity*/

, N0 d6 [; g6 x9 Huse R_A for n 60,10 min /*Resource A*/

send to P_B
end

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
