在相关研究基础上，基于突变理论，建立了建筑设计方案综合评价和优选的突变级数法。首先对建筑设计方案的评价目标进行多层次分解，从使用功能、技术性能、经济指标和环境效果等四个方面，建立建筑设计方案综合评价和优选的递阶指标体系，然后对评价指标属性值数据进行归一化处理，根据相应的突变系统数学模型计算突变模糊隶属函数值，最后计算评价目标的总突变级数值，据此对建筑设计方案进行评价和优选。实例研究表明，该方法可靠性高、客观性强，为工程实践中建筑设计方案评价和优选提供了新思路和途径。%In the basis of the previous researches,assessment index system of architectural design scheme is presented in this paper,and catastrophe progression method of scheme optimization of architectural design based on catastrophe theory is put forward. Firstly,the multi-level objects of architectural design scheme evaluation are analyzed,and four factors including use function,technical characteristics,economic indicator,and environmental effect are taken into accounted synthetically to construct the hierarchical index system for the evaluation and optimization of architectural design schemes. Secondly,standard quantization of attribute values of assessment index is performed,the catastrophic fuzzy affiliated function is constructed based on the corresponding catastrophe mathematical model,and the ultimate catastrophe progression values are calculated,which can be used to assess and optimize architectural design schemes. The study shows that catastrophe progression method has practical value in the evaluation and optimization of architectural design schemes.
