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," a, E% t( R' a1 e* Q
  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.4 C1 h; g3 s) D+ Z
  Loads are processed by each operator for the following time:$ f1 g$ N/ w% f
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.8 N2 `- ^, Z# y8 g) ~8 q" R  @9 q3 p
  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.- P( X- ?/ f5 w7 M. L% W/ k3 I7 k
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 Y- O6 X! `/ @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.3 `% Y  V( q7 C% R/ A/ N
# f: g/ k# [, J
问题:1 i7 u( V& ^1 G! ]
After running the model for 10,000 days, what was the average number of loads in each process?6 X, y2 n8 n& H3 n

不胜感激!

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