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,
" U1 ~' d$ x! m; \; e 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.
, x$ R7 v% `7 I! E! J, _+ g Loads are processed by each operator for the following time:
1 K& {8 S& o$ A: d% D1 D Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.7 H4 X$ z& `4 g* O( L% s
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% L' |1 |/ l' e; _
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% X' o. ~; n/ U
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.4 l. r- [3 q) }+ w5 @1 u$ E
