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,
& l) E! v% v- I8 q7 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.
# x' J$ _) I9 @/ g Loads are processed by each operator for the following time:
+ Z1 N( m: h- _2 ? Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! \: T+ a5 W. d9 p; R+ B" E
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.; q7 U1 p# S( {$ [9 d) n1 e2 `
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! E [: l4 ?+ j# x
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.8 C4 Z" z: ?) R: S; Y. R, @
* K+ @% q1 @' S5 @, p& s3 {8 [$ A- O问题:3 a! z* x' w" C
After running the model for 10,000 days, what was the average number of loads in each process?0 {4 K8 n" O1 y8 i& C" f6 z
/ R% S; p4 N* A0 }# G& B" H不胜感激! |
