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,
2 l5 ^) d& X) B. T: f 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." h# ?7 E) M0 ]) ]2 z
Loads are processed by each operator for the following time:
$ G P% x+ s, G2 f4 { Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. O" W& c5 J, L7 b$ Y6 D7 j+ K( @
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.- b! ?2 I3 ?" ]6 ? v& `6 n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 P, ]6 W- P2 p" a! l- i+ GSend 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.
' r+ x* ^4 V3 @& g8 d; c# R2 ?( l) h: R
问题:- v$ l( e& n' B- v% `
After running the model for 10,000 days, what was the average number of loads in each process?
