Decision making in house of quality: A hybrid AHP-PROMETHEE approach

This paper discusses the problem of ranking technical requirements (TRs) according to customer needs (CNs), which is arisen from the final stage of the house of quality (HOQ) process. To rank technical requirements in a useful approach, the paper employs an integrated analytic hierarchy process (AHP) and PROMETHEE II approach; AHP is used to determine the relative importance of multicriteria, and PROMETHEE II is applied for final ranking of technical requirements. To analyze the quality and reliability of decision problem, the result of PROMETHEE II evaluation is represented by the geometrical analysis for interactive aid (GAIA) plane. A case study on an automotive part is put forward to illustrate the performance of the proposed methodology.
