运用多目标决策理论鉴定小麦品种抗病性的研究

A STUDY ON APPRAISING DISEASE RESISTANCE OF WHEAT APPLYING MOD THEORY

运用多目标决策理论——TOPSIS法鉴定了18个小麦品种的抗赤霉病性,结果与实际一致。TOPSIS法逻辑严明,方法灵活,结果精确,适用于各种类型的评价、优化,决策问题。在植物病理学研究领域中具有广泛的应用前景。本文给出了带权矫正过程的TOPSIS法通用BASIC程序,从而使大小规模的问题解决均成现实。

In this paper we have appraised wheat scab resistance of 18 wheat varieties applying multiobjective decision-making (MOD) theory.The results coincided with the practical ones. Of methods available in this theory, TOPSIS is characterized with precise results,strict logic and elastic usage,it can be used for solving numerous problems of appraisal,decisionmaking and optimization, and it has a great potential for application in plant pathology field.We have also given a general computer program of TOPSIS joining weight-correcting progress, so making the method much more practicable for many users.
