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,
& o' b. g+ p- a( b' j 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.
/ j- G0 X2 z2 K4 x' M! `/ Y' z Loads are processed by each operator for the following time:
, _* U/ f; |6 W q1 }. P Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% X# X% c/ t& \# e: P9 B
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( r* a1 c, }) E" S0 W. ~$ ^+ c
Worker_C does the job in a uniformly distributed time between 30 and 90 mins., X' w# G' W: ]0 O, P6 P' \9 Z7 F# @
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.! J8 d2 B5 b* \4 g1 m v. P4 \
