【摘要】 针对多目标决策问题,提出一种基于多种群进化算法的多目标并行博弈设计方法,利用Fortran语言编制了相应计算程序.将多目标设计问题描述为博弈问题,在博弈分析中,根据各博弈方在博弈次序和过程上具有同时性和独立性,采用并行计算技术.在以MPI为平台的集群环境中实现数值算例、补偿滑轮组变幅机构、拱型结构的多目标并行博弈设计.计算分析结果显示:该方法的计算精度高、收敛速度快、可以防止早熟、有较好的平衡负载能力,可有效求解多目标问题.更多还原

【Abstract】 For design of multi-objective decision,a new method of multi-objective parallel game design basing on multi-species evolution algorithm has been raised and carried out by Fortran. By describing the issue about multi-objective design into game theory problem and under the analysis of the game,the paper adopts the parallel computing technologies according to the synchronism and independence of each player in the game sequence and the process. MPI as a platform in the COW,realized the multi-objective parallel game design of numerical count cases,luff mechanism of compensative sheave block and arch structure.Analysis shows parallel game basing on multi-species evolution algorithm can not only converge efficiently but prevent precocity;it also has a better capacity of loading balance,resulting in a better robustness.It can resolve the multi-objective decision effectively.更多还原
