Qingdao pilot area water supply network fuzzy evaluation research

As the main part of city water supply system, water supply distribution network has such characteristics as foundation, complexity, openness which made it very difficult to manage and maintain. Combining Fuzzy Theory with comprehensive evaluation method is proposed to the characteristics of the water supply network through the GUI interface of MATLAB 7.7 established the visualization, intuitive safety fuzzy comprehensive evaluation system. The security fuzzy evaluation system is applied to the security evaluation of water supply system in Qingdao pilot area, and given this region grade of security of water supply pipe.
