基于可变模糊集理论的节水灌溉方式优选

Optimal Selection of Water Saving Irrigation Schemes Based on Variable Fuzzy Sets Theory

在分析节水灌溉的必要性和目前节水灌溉方案优选方法的基础上,根据可变模糊集理论,提出了节水灌溉方案优选的可变模糊优选方法。该方法能够通过变化模型参数,合理地选出优属度较高的方案,提高了对方案优选的可靠度。将提出的方法应用于某灌区节水灌溉方案优选,结果比较和分析表明,该方法计算简便,实用性强,优选结果可信度高。

Based on the analysis of necessity of water saving irrigation and the optimal selection methods of its scnemes, a new valuable fuzzy optimization method is developed for the optimization selection of water saving Irrigation mode according to variable fuzzy sets theory. The proposed method can properly select scheme with high optimal membership degree by varying parameters of the model. Therefore, the reliability of optimizing scheme can be improved. In this paper, it is used for the optimal selection of water saving irrigation schemes of certain irrigation district, and the comparison and analysis of results indicate that the proposed method is simple, practicable and having high reliability.
