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,
3 k& y+ s# _: f" R% Z: B! G 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.
, h- n* O H! J6 T! i$ P' S Loads are processed by each operator for the following time:
" G& ^( z/ J. l, ? Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. e, d* Y i& K8 `4 \, Z6 q
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.
* T% e, L* `, [. z6 C$ _4 t _% X2 N Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 t e' E! j6 e5 ?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.
$ i" D9 I" v. k% g
6 [4 K f- l; g0 e9 V+ v问题:
; S1 v4 L5 I8 E; D" Q0 R1 uAfter running the model for 10,000 days, what was the average number of loads in each process?
% ^8 B5 M A, o1 v% N4 v3 c, U Y* L, H- H$ h' ^0 [+ W3 ?
不胜感激! |
