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,
) W% x+ X, g* W& q$ 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.: _# s" ?4 S. P$ L
Loads are processed by each operator for the following time:4 ]+ }2 b+ d/ T; _) B7 g. a& ^( r1 H
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 J3 L5 n4 F* j8 N8 d 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.2 Y6 Q* E! w4 M4 M5 ?, v
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& w8 _' _3 v7 E. `$ qSend 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.
! W3 I5 u4 b* y! Q: a* k; e) i3 T: x1 a& Y3 C- v. t" k' C
问题:. B8 H! B, j# |4 g
After running the model for 10,000 days, what was the average number of loads in each process?
" T6 Y! I8 e* ^6 ^0 e/ }6 j8 L
不胜感激! |
