Abstract

Considering inappropriate decisions on design concept at the early stage of development always lead to huge cost involvement and ultimately drive towards premature component or product failure. The project emphasize on simultaneous decision using analytical hierarchy process (AHP) at the conceptual design stage to assist designers in making the right decisions during the development process of products. The development of automotive fender was chosen as a case study to depict Analytical Hierarchy Process (AHP) method is the best way in selection the best design concept. AHP is also used to identify the factors that influence the conceptual design. Besides that, Expert choices software is used for evaluation and sensitivity analysis the design concept. To demonstrate the proposed design concept selection framework, five different design concepts were considered. The results revealed that Design Concept 5, DC5 with highest priority percentage 28.5% is the best automotive fender design compared to other design concepts. The final judgment of the design concept is gained by performing 4 scenarios of the sensitivity analysis and the analysis showed that is proven DC5 is the best design for automotive fender.
