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,! u4 ^5 M8 A, t. s
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 _ w q# p" U9 ~- h, I Loads are processed by each operator for the following time:
) y" w& P3 ~) H6 K2 v5 X$ R. C* i Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' o3 r8 W" W3 S9 i' n 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.- D( @& h. W) H( {6 t* V# `; r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 r3 Y' t8 X0 P* k6 d
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.; P( M% F m8 f- |3 e& [, y
/ p; w4 [: X$ V9 W4 t* H; |
问题:
& b- Y9 i: Y% Y# b' p* zAfter running the model for 10,000 days, what was the average number of loads in each process?( @6 Q) I! U5 W7 r- @; x; Y/ c

不胜感激! |
