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,9 r; O* ?' F0 x1 T8 F. D7 w
  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.
0 {: T$ l8 R$ z* l0 j" x3 O  Loads are processed by each operator for the following time:2 F. n- s/ M% W
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! e& |+ d6 k7 H  R/ H7 R7 ]
  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., p2 l) k* t1 r
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! Z+ Z4 R2 x7 w+ q
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.; r5 G( h1 Z' E4 J- m3 q8 n

After running the model for 10,000 days, what was the average number of loads in each process?+ H/ W$ D6 c! i8 Z

不胜感激!

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