A Coordinated Development Evaluation Modeling in Water- Socioeconomy -Environment System

A coordinated development model in water–socioeconomy-environment system (WSE system) and its application are presented in this paper. Based on complex system theory and the coordinated development idea, a set of indicators is provided with capacity to evaluate coordinated development degree in WSE system. Integrating variable fuzzy set theory (VFS) and entropy weight (EW) into set pair analysis method (SPA), the authors derive SPA-VFS-EW model to describe development degrees of WSE system. Employing coordination theory, the authors develop a coordination model based on Euclidean distance, followed by a coordinated development model. The derived model is applied to assess the coordinated development degree of WSE system in Shaanxi province. The results are found satisfactory. It also indicates that the proposed model in this paper can provide a novel method for evaluating the coordinated development in systems.
