基于模糊层次分析法的既有住宅性能综合评价

以综合改建为目的,将既有住宅性能分为安全性、完好性、适用性、节能性、环境性和协调性等6类指标.运用模糊数学方法对层次分析法进行改进,确定各指标的权重,构建既有住宅性能综合评价模型.克服了传统评价方法的主观随意性,全面考虑各类指标的相互影响关系,改善评判过程中的不确定性.通过评价30个不同的案例,验证该评价模型具有综合性、客观性和可操作性的优点.通过案例讨论,提出各类住宅性能改建的实施方法.

Comprehensive Evaluation on Performance of Existing Residential Buildings Based on Fuzzy and Analytic Hierarchy Process

The refurbishment of residential buildings is to improve living quality and protect historical culture effectively. On the purpose of improving performance of buildings through complex refurbishment, the performance of existing residential buildings in this paper is measured by six indicators such as security, intactness, fittingness, energy-saving, dwelling environment, and coordination. In order to overcome the shortcomings of random and subjectivity in the traditional evaluation method and to eliminate the uncertainty during the evaluation process, a comprehensive model for evaluating performance of residential buildings is suggested, where the weight of each indicator is determinate based on an improved Analytic Hierarchy Process (AHP) method combined with fuzzy analysis of the relevant relationship of each indicator. The case of 30 different residential buildings is evaluated and then reveals many advantages in this model that evaluation is comprehensive, objective, and operational. By discussion of case study in the end, several reconstruction approaches are suggested in improving performance of existing residential buildings.
