基于模糊双射软集合的内河岸线资源KDD模型

A KDD Model for Inland River Shoreline Resources Based on Bijective Fuzzy Soft Sets

内河岸线资源评价与分析方法主要是针对定量数据,而一些影响岸线资源价值的因素是定性的、模糊的,传统方法在处理此类问题时存在局限。针对该问题,本文运用近年来国际上新兴的不确定问题建模理论——软集合理论,考虑模糊环境,结合基于依赖度的模糊双射软集合参数约减方法,提出了一种基于模糊双射软集合的内河岸线资源评价KDD模型。本文采用重庆港区15个港口进行KDD分析。结果表明本模型能够提取决策规则、分析关键因素及其依赖度,并得到了有参考价值的决策建议,验证了该模型的有效性。

Classical assessment and analysis methods for inland river shoreline resources mainly process with quantitative data. However, some significant factors that affect the evaluation of inland river shoreline are qualitative and fuzzy. Thus, classical methods have difficulties in solving this kind of problem. Motivated by this issue, this paper employs soft set theory, an emerging mathematical tool for handling uncertainty, to propose the KDD model for inland river shoreline resource based on bijective fuzzy soft sets, which considers fuzzy environment and combines the reduction method based on bijective fuzzy soft sets. Moreover, this paper uses 15 ports of Chongqing port area to proceed with KDD analyzing. The result shows that the proposed model can find the decision-making rules and analyze the key factors and dependency, and obtains Some instructive decision-making proposal, which validates the model.
