This book focuses on the implementation of Quality Function
Deployment (QFD) in the construction industry as a tool to help building
designers arrive at optimal decisions for external envelope systems with
sustainable and buildable design goals. In particular, the book integrates
special features into the conventional QFD tool to enhance its performance.
These features include a fuzzy multi-criteria decision-making method, fuzzy
consensus scheme, and Knowledge Management System (KMS). This integration
results in a more robust decision support tool, known as the Knowledge-based
Decision Support System QFD (KBDSS-QFD) tool. As an example, the KBDSS-QFD tool
is used for the assessment of building envelope materials and designs for high-rise
residential buildings in Singapore in the early design stage. The book provides
the reader with a conceptual framework for understanding the development of the
KBDSS-QFD tool. The framework is presented in a generalized form in order to
benefit building professionals, decision makers, analysts, academics and
researchers, who can use the findings as guiding principles to achieve optimal
solutions and boost efficiency.
