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, K) Z1 [* I' u6 H" A 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.
9 s: \3 f6 W. D4 S Loads are processed by each operator for the following time:
) t( C0 F4 h% d' g4 r Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 P( O* F( ^, m+ w% B 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.
$ t3 E- T& L0 J2 F* e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 E) F) h7 ?$ f( }$ C* \6 v- pSend 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.2 Z( n, u6 R* m6 D% _) P: w6 c
( i# C: _+ Y0 N, T% l O+ t8 M问题:! W8 p% F! q c- c# ^" q3 K) p$ }
After running the model for 10,000 days, what was the average number of loads in each process?% d# P5 W% n' K8 u! `
" J; Z2 M% I; q# V3 m. v不胜感激! |
