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,
; E) C: m& D2 q% V 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 d2 a3 e- z$ o2 S0 w Loads are processed by each operator for the following time:" U" Y" h: b, A% j
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% g5 Z9 }* e& G2 T 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.# \ O# b$ j! {
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) d& U: q$ c6 m: Q3 {. ?. ~
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.
, x7 q( S; L( O* ~
' k% x" {* y4 J" ?6 \9 Z$ i& L, m问题:5 C7 _+ Y9 n. B8 S6 i2 o
After running the model for 10,000 days, what was the average number of loads in each process?
% s/ C0 v _- D7 L, x' x% ~9 G. L5 c) P3 J& t; ~; A; u& |/ m
不胜感激! |
