The Methodology for Selecting Product at Conceptual Design

The methodology for selecting products at conceptual design is addressed in this article. This method evaluates both qualitative and quantitative variables based upon Product Design Concept (PDC), which uses the Quality Function Deployment for Environment (QFDE) and Analytic Hierarchy Process (AHP) methods. The Qualitative variable design parameters and design criteria from Voice of Customer (VOC) were first deployed. Secondly, Design for Environment (DFE) Technology was also used to analyze the Design Performance. Thirdly, alternative products based on the VOC and DFE were designed. Lastly, all of qualitative and quantitative criteria were used to evaluate the use of AHP to meet design requirements with which the detailed design was implemented. In this study, an inkjet printer is used for illustrating presented methodology. Result from the study depict that the designer can better select the appropriate green product design alternatives at conceptual design phase
