农业工程设备选购模糊综合评价与实证研究

Fuzzy comprehensive evaluation and empirical study on the selection and procurement of agricultural engineering equipment

农业工程设备选购对于农村经济发展具有重要的意义。首先以农业工程节水灌溉设备为例,建立选购评价指标体系,然后确定隶属度函数得到模糊关系矩阵,运用层次分析法确定水肥一体化设备选购评价指标体系中指标的权重,得到权重向量,通过合成模糊综合评价结果矢量,最后运用最大隶属度原则得到综合评价结果。选取一家农业合作社作为应用对象,通过对其水肥一体化设备选购的分析,为农业合作社大型农业工程设备的最优化选购提供一个重要的依据,以促进农村经济的发展。

The selection and procurement of agricultural engineering equipment is of great importance to the development of agricultural economy.First of all,taking agricultural engineering water-saving irrigation equipment for an example,a selection and procurement evaluation indicator system is created and then a fuzzy relation matrix is set up based on subordinaling degree function.Next analytic hierarchy process is adopted to con firm the weight of indicators of evaluation in dicator system for the selection and procurement of water and fertilizer integrated equipmenl,thus obtaining weight vector.Through synthesis of the vector of fuzzy comprehensive evaluation results,comprehensive evaluation results are acquired based on maximum membership principle.Choosing an agricultural cooperative as application object of the system,an analysis on the selection and procurement of water and fertilizer integrated equipment is carried out,which provides an important referenee for the optimal selection and procurement of large agricultural engineering equipmenl for agricultural cooperatives and promotes the development of rural economy.
