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,
' Z/ ] s% [. X9 c0 P 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.
3 F) ^9 o2 v) r9 K2 V. q' ]2 ^ Loads are processed by each operator for the following time:" C" Z& Q! A0 N' }+ 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 o! ^, W$ ^6 T# K. R9 o 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.
; w; n4 G: S3 w6 H$ | Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* I2 v4 _3 E* N2 @
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.( c9 R. x+ h7 e
5 y) k2 f$ c: i Y" F6 q) P- Y! `
问题:3 B3 l1 D; ^% F1 ]9 Q
After running the model for 10,000 days, what was the average number of loads in each process?. C( P2 l( Y, C/ e, H' \6 j: i; |
