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,' P9 h& S: {) ]" {% _+ u# H6 i1 W% y
  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.% Q# W# U9 g% p+ @
  Loads are processed by each operator for the following time:
5 a+ J2 J6 R1 E- ?  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' B7 ~' u- M$ }: u1 t  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.# ?6 l3 {$ d" X% }1 b* P& l
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- P* }: u' d; s  B# s" O( JSend 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.  ^9 R8 N  Y6 v

After running the model for 10,000 days, what was the average number of loads in each process?) j4 `7 y+ U) y6 Q: M$ y! P9 y+ V

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