Hybrid ANP: QFD—ZOGP Approach for Styling Aspects Determination of an Automotive Component

Abstract

Styling of automotive products is a vital issue and it need to be imbibed with increased customer expectations during every stage of product design. In order to achieve effective styling, it is necessary to apply quality function deployment (QFD) approach which is an effective product and system development tool. This study presents a decision framework where analytic network process (ANP) integrated with QFD and zero–one goal programming (ZOGP) models are used in order to resolve the design requirements which are more efficient in achieving aesthetic design. The first phase of the QFD is the house of quality (HOQ) which transforms customer requirements into product design prerequisites. In this study, after determining the sustainable requirements named voice of the customers (VOCs) and Engineering metrics (EMs) of an automotive component, ANP has been employed to determine the importance levels in the HOQ considering the interrelationships among EMs and VOCs. Additionally ZOGP approach is used to take into account different goals of the problem. A case study was presented to exemplify the approach.KeywordsAnalytic network processQuality function deploymentHouse of qualityZero–one goal programming
