灰色关联投影法在节水灌溉方案选择中的应用

Application of grey relation projection method in selection of water saving irrigation plan

文章提出了用于节水灌溉方案选择的多目标决策灰色关联投影法,介绍了该方法的基本原理,建立了综合考虑项目的安全性、可靠性、地形适应性、作物适应性、施工难易程度等因素的节水灌溉方案。选择多目标决策灰色关联投影模型,并用实例加以说明,所得结果与层次分析法的评价结果基本相同,说明该方法用于节水灌溉方案选择是有效的[1]。

The paper puts forward multi-objective decision grey relation projection method to select water saving irrigation plan,introduces basic principle of the method,establishes water saving irrigation plan comprehensively considering security,reliability,adaptability to topography and crop,construction difficulty,and so on.Take the project as an example,the detained results are almost samilar by using this method and multiple analytic hierarchy process,then the seletion of the method is efficient.
