基于综合权重及投影评价模型的水稻品种筛选方法

A Selection Method of Rice Varieties Based on Comprehensive Weight and Projection Model

首先从有利品种筛选的角度,依据各品种指标值采用离差最大化方法确定评价指标的客观权重,然后综合考虑客观权重和决策者给出的主观权重,确定既反映主观权重信息,又反映客观权重信息的综合权重,进而提出一种基于综合权重和投影评价模型的水稻品种选优方法。运用该方法对广西2011年早稻迟熟组13个品种进行了比较筛选。

In order to select good rice varieties,major traits（ indices） were chosen to be used for evaluation. According to survey values of each evaluation index,the objective weight was firstly determined by the maximizing deviation method. Combining with the subjective weight of each index defined by the decision maker,the comprehensive weight of an index was then calculated,reflecting both the subjective favouritism and objective information. Finally,the method to select good rice varieties was developed on the basis of the comprehensive weight and the projection model. Furthermore,this method was used to conduct comparison and selection among 13 varieties in the late-maturing group of the Early Rice Regional Trial of Guangxi in 2011.
