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，
; J; `4 T% [  V  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.
" ^1 e; m  G6 ?/ j# p7 F9 j, v1 ~4 s  Loads are processed by each operator for the following time:
! I+ W+ D, z+ u: T! b  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( V3 y- v" A! U/ i; f( }" {  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.
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.
* ~' r) q* k' U" n" v+ Z1 q4 o
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

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