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,
, H1 c Y1 {# _8 H0 H 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.# ` a- M ?6 u! P: C9 U+ O l
Loads are processed by each operator for the following time:$ f: b3 Q0 ]0 d: D* p! C: a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- m( a6 { `' r- p, S/ l 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.1 E' @# Q- v' E) G
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
k9 V% O) D: o0 j8 P9 M- _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.) K' x* ^' N# L) G: D5 {
6 l# J" A- ?/ U' {9 g4 M- T- T, x: m
问题:
5 i/ Q n; Q* i2 N7 WAfter running the model for 10,000 days, what was the average number of loads in each process?
7 e* ~* e- s; f: K- ~6 j, K6 i; M+ w, l
不胜感激! |
