Fuzzy QFD for Process Synergy Management in Construction Projects

Construction project development is a complex process that involves various parties to implement various process stages. It is fragmented and usually undergoes several rounds of design evolution, and as a result the basic and original customer's requirements may be easily sidetracked or may deviate from the client's objectives. Quality function deployment (QFD) is a systematic methodology that can be used to keep track of customers' requirements. The aim of this paper is to propose an original approach for the process synergy management of construction project. The approach is based on the QFD, and fuzzy logic is also adopted to deal with the ill-defined nature of the qualitative linguistic judgments required in the proposed house of quality (HOQ). Specifically, the paper addresses the issue of how to deploy the HOQ to effectively and efficiently improve construction project development processes and thus customer satisfaction.
