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,) T% q% l, a3 \; P* @+ Z1 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.
- Q, ^$ }5 _8 K0 Z3 R Loads are processed by each operator for the following time:
+ n* P/ D# Z/ E( s& c Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! I( {/ f _. W' f( `7 z 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.
* W$ a) `3 C+ e4 G( [$ B* g3 H Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& z" r7 B# c+ H9 \- d( ~
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.& h+ @0 K+ b, t& N% O- z6 N
( ~9 d4 y5 X% a: C) L+ c) s
问题:
