[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。
[Objective] The research aimed to establish a multi-attribute decision-making method based on attribute difference degree and explain its application in rice optimization. [Method] The concept of close degree between attributes was proposed. On the basis of this, the differences between attributes were studied, and the method of weight determination based on attribute differences was analyzed. [Result] A multi-attribute decision-making method based on attribute difference degree was obtained, and the application and feasibility of the method for rice preference problem was demonstrated. [Conclusion] The problem of determining the weight of attributes in multi-attribute decision-making was enriched, and provided the necessary theoretical support for the scientific and rational selection of rice varieties.
