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:
4 S5 Y# t) U9 X% v  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ ^( x* P; H' S. m5 U! Z  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.
- l* k  p# ^& }: U- x& d/ J  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" v5 C0 R! P. hSend 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  U# a: K3 j. X- q( G问题：
After running the model for 10,000 days, what was the average number of loads in each process?

send to P_B

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.
