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,
4 J T& a# d0 ]' D! K8 x 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./ b# F+ j* C/ `" _6 H6 y
Loads are processed by each operator for the following time:& |( V: y( j) k+ D
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 B! O& l: u- [- Q+ d 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.0 Y' {2 a& P3 G# R& C; ?; [* g/ E
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% f8 N0 s2 u3 A6 \7 S8 V: `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.
& r# T! o" q7 [7 j% \
) X; q9 o" C- W) T+ g( `8 \问题:
7 K( v* x4 _; R; ~5 w8 _After running the model for 10,000 days, what was the average number of loads in each process?9 `3 l* P9 n$ c) A3 h) A! _
9 U3 Q+ ~) r& ~, i不胜感激! |
