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,# o+ ^& P$ o1 I/ A% b, ?
  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.& T' i/ \8 e8 t# V% b  {  W+ d
  Loads are processed by each operator for the following time:) @  A1 A/ s# b& C) ^& y$ K" T
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, [$ g! {6 o( E  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.8 u; H" X5 l5 u# [
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, d, f/ ?1 i) k3 _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.+ ~0 `% L! a$ a" w6 ^
& I' r' G2 H( Y* c
问题:" Y# N' W4 J0 q# u& W* ~& N
After running the model for 10,000 days, what was the average number of loads in each process?& R2 P: @- n. ?! r8 Z

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.3 K( E; ~" D9 H6 H3 z

Remember to turn off the animation before you run your model.
