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,
7 E( O5 b4 a |% b 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.
* ?2 k1 I% {0 k7 e" y, x Loads are processed by each operator for the following time:
. q4 m4 }5 R l: X; a! T Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- s" G7 \6 U* w8 e) 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.+ z' N% e8 _1 B7 j7 y/ b' U6 J
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 X5 }) H9 M) }0 y' p. b* G0 A
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.3 S# N; t' x* k6 f& B9 J5 t
C' `" d: f6 ?7 P2 f
问题:
- M8 b, S8 U! MAfter running the model for 10,000 days, what was the average number of loads in each process?
6 w, ^" {1 V9 }
2 v+ ?* k6 }1 S# A/ `不胜感激! |
