模糊综合评判在晚熟玉米杂交种评价中的应用

Applications of Fuzzy Comprehensive Evaluation in Late-maturity Hybrid Corn Assessment

晚熟玉米杂交种的品种特性具有一定的模糊性.基于模糊数学理论,对玉米品种特性的模糊性进行数学分析,利用"隶属度"的渐进性建立数学模型.通过选用恰当的隶属函数对评价因素进行描述,并根据层次分析法确定各评价因素的权重,运用模糊综合评判方法,建立了一个合理、有效的晚熟玉米杂交种的评价模型,为玉米品种的选择和鉴定工作提供了理论依据和数学方法.

The late-maturity hybrid corn varieties have Iuzzy cnaracter,to analyse the fuzziness of the corn varieties, and the gradualness of ＂membership＂ is used to establish mathematical model. Through building the membership functions between factors set and judgement set, giving the weights of correlative factors, according to analytic hierarchy process, and using fuzzy comprehensive evaluation method, we established a reasonable and effective late-maturity hybrid corn evaluation model. This work can offer some good theories and mathematic method to select and appraise corn varieties.
