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.
) g  m( n/ A7 Q- X( l: P  Loads are processed by each operator for the following time:
) J5 }: l7 {4 V# Z: p: Z  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.
0 \( ~3 o( `6 k  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 Z0 ]% X4 _2 SSend 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：
0 [' E0 k9 \$ \- ?) D. i: ]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*/
- l, T- C+ i( g3 i* c9 ]& g! Smove into Q_process /*Single capacity*/

P_B and P_C is similar

: x9 R" p- q! Hin 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.
