可建造性设计决策中的模糊质量功能配置方法

A fuzzy-QFD approach to buidable design decision-making

质量功能配置(QFD)方法作为一种集成决策方法,有助于在满足顾客需求情况下将设计要素和建造过程诸要素联系起来。在常规QFD方法的基础上,通过对质量屋(HOQ)的改进并引入模糊集合理论,建立了可建造性设计决策中的模糊质量功能配置(Fuzzyqualityfunctiondeployment,FQFD)方法,研究了模糊质量功能配置方法在可建造性设计决策中的应用问题。具体的应用示例证明了该方法的可行性。

During the conceptual stage of a building design,major design decisions that have the greatest influence on buildability of a project are taken.Quality function deployment（QFD）is an integrated decision-making methodology that can assure and improve the alignment of elements of design and construction processes with the requirements of customers.Based on traditional QFD,This paper studied a fuzzy quality function deployment（FQFD）method to bulidable design decision-making.In the research,the House of Quality（HOQ）is adapted to meet the needs of buildable designs in the construction industry and the fuzzy set theory is integrated into HOQ to capture the inherent impreciseness and vagueness of design-relevant inputs and facilitate the analysis of design-relevant QFD information.An example is presented to illustrate the feasibility of the proposed method,which provides a viable decision-making method for quantitative buildability evaluation at the early design phase.
