Study on fuzzy comprehensive evaluation of rural house energy-saving renovation demonstration effects

Qualitative analysis and quantitative evaluation are the main methods for demonstration effect evaluation. The essay takes L·A·Zadeh´s fuzzy comprehensive evaluation theory as the basis and the demonstration effect evaluation indicator system for the Balinzuoqi Rural House Energy-saving Renovation Demonstration project as the object to build the demonstration effect fuzzy comprehensive evaluation model for the rural house energy-saving renovation demonstration project in light of the diversity and fuzziness of the indicator system. It made use of the model to evaluate the demonstration effects of Balinzuoqi Demonstration project and demonstrate the feasibility of the model built through operation of the fuzzy relation of the evaluation indicators. Building the demonstration effect fuzzy comprehensive evaluation model largely depends on the distribution of every evaluation indicator weight and determination of the grade of membership of the single factor indicator to the comment set. This is the main basis to quantify the stationary indicators and also the basis to ensure fuzzy comprehensive evaluation model accuracy and objectiveness of the evaluation results.
