Abstract: Abstract Quality Function Deployment (QFD) is commonly used to translate customer requirements into design specifications in the product conceptual design phase. House of Quality (HOQ) is an essential part of QFD to map different requirements of product solutions using a design relationship matrix. In traditional approaches, the way of deciding weights in the relationship matrix can lead to a distortion in ranking of technical measures. Although some methods like Analytic Hierarchy Process have been proposed to improve this problem, they require additional data collection and process. This paper introduces two effective approaches based on Best–Worst Method and Full Consistency Method (FUCOM) to decide weights of technical measures in the relationship matrix of HOQ. The novel integrated approach of FUCOM-QFD is developed for rapid weight allocation in the relationship matrix. The proposed BWM-QFD and FUCOM-QFD approaches use consistency ratio and total deviation measures in reliable decision-making. They not only reduce data collection, but also improve inconsistency problems. The vector-based pairwise comparison and consistency measure are two important features of the proposed approaches. A case study demonstrates improvement in the efficiency and accuracy of weighing solutions for technical measures compared to the existing methods.
