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,
" e, l' q5 G4 m2 l- _, m' e# g 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.7 E( x# ~2 e1 O" k; H( W
Loads are processed by each operator for the following time:
& Q' |0 g% t: O! B Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 U0 x4 V; S8 e) c3 H 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.
. _5 u' M0 [, i5 q: S' W' r+ n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.+ C% ^/ }1 ]+ z2 n0 `; q
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.
) ?; K1 d1 b/ F' I: T3 G' r+ T ]2 j; `2 J+ T$ [
问题:) C! b6 Y( ~+ @& ] w$ y
After running the model for 10,000 days, what was the average number of loads in each process?! ^3 V# _ D2 Y5 }; v- R8 R8 u5 f
/ V4 B1 l: O i1 {
不胜感激! |
