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,
$ k* G! F1 {! O3 c( j% d 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. I d* p' b; _( x* X& z
Loads are processed by each operator for the following time:. g) h5 I6 N6 Z* T( O) ^9 h; Q0 [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. T& m. W( m( {- P( L
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.
+ {" j9 O" T1 s, w, e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 C( q" t- Q4 m- o
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.; Y$ g: K9 D. b ?* |+ S" I" e2 g
" s+ W. ^: _* J$ X2 _' P4 x问题:' ?# e. Q c' z, _) S
After running the model for 10,000 days, what was the average number of loads in each process?/ C% w$ Q5 ?+ g9 A A1 H
" M" s: J0 Q, H% `0 q' a: U- _9 z
不胜感激! |
