基于属性差异度的多属性决策方法及其在水稻优选中的应用

摘要

[Objective]The aim was to establish a multi-attribute decision making method and introduce its application in rice breeding.[Method]Based on the defined closeness degree among attributes,the difference degrees among attributes were discussed.Furthermore,the weights of attributes were determined based on the difference degrees among the attributes.[Result]A multi-attribute decision making method based on difference degrees among attributes was established,the feasibility of applying it in rice breeding was also analyzed.[Conclusion]This study enriched the methods to determine attribute weights in multi-attribute decision making and provided the necessary theoretical support for selecting rice varieties scientifically and rationally.%[目的]建立基于属性差异度的多属性决策方法并说明其在水稻优选中的应用。[方法]提出属性间贴近度的概念,在此基础上对属性间的差异度进行研究,并对基于属性差异度的权重确定方法进行分析。[结果]得到了1种基于属性差异度的多属性决策方法,并针对水稻优选问题说明了该方法具有应用及可行性。[结论]丰富了多属性决策中属性权重确定的问题,并为科学合理地选择水稻品种问题提供了必要的理论支撑。
