基于GASA和粗糙集的BT项目投资方融资方案选择研究

Study of Financing Package Choosing for the Investment Project Owner of BT Project Based on GASA and Rough Sets Theory

摘要:

本文构建了一套适用于“建设—移交”(BT)项目投资方的融资方案指标评审体系，探讨设计一种基于粗糙集理论的融资方案选择方法。通过遗传模拟退火方法对数据进行离散化处理，利用粗糙集和条件信息熵的方法计算指标评审体系中属性的权重，将求得权重代入传统的灰色关联分析评价法中计算加权灰色关联度，同时改良了灰色关联分析法的准确性。实现了遗传模拟退火、粗糙集、灰色关联分析等理论的良好耦合。

Abstract:

This paper constructed a set of suitable for Build-Transfer(BT) projects investment financing index evaluation system, Designing a financing plan selection method based on rough set theory.Use the method of Genetic Algorithm Simulated Annealing to discretization data.Using the method based on rough set and conditional information entropy theory to calculate the weights of attributes in the index evaluation system.Put the weight into traditional Grey Relational Analysis evaluation method to calculate the weighted grey correlation degree also improved the accuracy of Grey Relational Analysis method.Realized a good coupling of Genetic Algorithm Simulated Annealing, rough set theory and Grey Relational Analysis.
