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,
4 G# Y5 X. r6 `! }  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.% {' L4 e$ W  v) Z: n9 E/ g' H$ z
  Loads are processed by each operator for the following time:4 ?4 a( ^5 F5 F* _2 E/ x4 L
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) t8 {/ e# x$ Y" T! P. E- B5 L3 s  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.
1 V: Y- W8 l  ?, d0 |1 E4 j  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- e) }- H8 ^4 p( X$ q4 M
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.9 l/ k% {$ f/ h! }

4 l# H( S' h7 m) q9 V0 a, i问题:; Y2 r$ g( t. q$ t. X# R* [
After running the model for 10,000 days, what was the average number of loads in each process?% d: d! D$ q* D- P/ y1 E

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