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.
% v3 H/ @2 _$ z$ `0 C. r$ ^' Q  Loads are processed by each operator for the following time:
) C) o& Q$ p# v- H  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 s4 ]  q) R, N. J% J& [; I: w  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.
# F  T7 |" `$ N8 Y4 NSend 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.
! Q8 h! j6 b% g) Q/ g2 g5 q
问题：
% v6 Z' y0 J" m: F' f/ B* }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*/

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.
