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,
# k* d9 |+ X* v+ U2 h5 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.
$ ~7 V: `. L' ~8 V Loads are processed by each operator for the following time:
$ ~5 W6 G1 Z' B1 N1 J$ V Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 t ^7 l0 @3 }! j8 u$ q$ Y+ y 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.
" R7 m9 {( Q/ N; m) n Worker_C does the job in a uniformly distributed time between 30 and 90 mins. |$ N# Q% x! T W$ e
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.
' b! {, B0 f9 J
$ l8 R$ K/ @1 P! O+ v问题:8 p4 B; N) t/ j2 _. W& n$ Y% g
After running the model for 10,000 days, what was the average number of loads in each process?
' Q, T) k7 H/ s" S$ t+ l W% y; u7 M2 v, Y# u! h
不胜感激! |
