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，
2 @7 W% ^) z2 y2 ]2 j 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.
) H0 n( D1 F- N. j8 S Loads are processed by each operator for the following time:- I7 Y' d, U9 e7 \
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 n! C6 a8 r h0 f3 i- f! k 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.
0 G% t9 [. V3 h3 O" ~9 v' E" |% o( O Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ {* A- O* v' U! F) z
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.
7 X9 k* h) G8 N p) c' O4 E& q1 ^8 \+ g- H3 }
问题：5 x+ C, ^2 f& q
After running the model for 10,000 days, what was the average number of loads in each process?. J( C& ^! }. [" e$ K9 B
# ]2 ^: T2 [% z6 ^* c4 Y
不胜感激！ |
