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,
- \' S( m. b( M* [ o7 U 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.$ d( r% M0 m; M5 z! K5 G
Loads are processed by each operator for the following time:9 o! T1 p' |4 b# u3 r4 P( g
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 H9 K: G/ [" ^ C% Q3 U& _ 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.8 C2 i. Y# @5 J" Y2 `7 J
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% E! i# Z W7 o. m2 ?! ~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.2 a/ N- @/ q# z
2 g: w( K- k+ w7 ]5 ^
问题:
7 c+ ~4 ?* `" ~9 b4 zAfter running the model for 10,000 days, what was the average number of loads in each process?* S: a* g( `( b
: p% X2 c7 }! h8 m2 _% }, Q) t
不胜感激! |
