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 V9 k3 v3 O. d' X" ^
  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.
% Z( O" f- y1 L$ g* X/ C8 Y6 V  Loads are processed by each operator for the following time:$ l6 }) ]# B, j( a+ L4 A& e$ W
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ x9 j+ `" v& \5 A0 U+ E9 C6 ]  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.
" q, A1 ^* {5 Q6 \) {7 c& z' |, J3 a9 y% I  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.  c2 q# ]8 U; G4 s1 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.  h! C2 t! h3 D
9 @$ U! ]) }/ N* H- x
问题:9 h3 E( U0 D* m" L. O5 n& I
After running the model for 10,000 days, what was the average number of loads in each process?
