Abstract

As a useful product development technique, quality function deployment (QFD) can convert customer requirements into suitable engineering characteristics for maximum customer satisfaction. Nonetheless, the traditional QFD has been extensively criticized as having many defects in practical applications, which include the crisp evaluation of relationships between customer requirements and engineering characteristics, and the non-robust ranking of engineering characteristics. In this paper, we put forward a new method using double hierarchy hesitant linguistic term sets (DHHLTSs) and axiomatic design approach to enhance the performance of the classical QFD. Firs, the DHHLTSs are employed to evaluate the relationships between customer requirements and engineering characteristics. Then, the axiomatic design theory is extended to derive the prioritization of engineering characteristics in QFD. Additionally, a maximizing consensus method is used to determine the weights of experts considering inconsistency among their opinions. Finally, an empirical case of a shared car manufacturer is provided with a comparison analysis to demonstrate the feasibility and effectiveness of our proposed QFD approach.

摘要

作为一种有用的产品开发技术，质量功能部署 (QFD) 可以将客户需求转化为合适的工程特性，从而最大限度地提高客户满意度。尽管如此，传统的QFD在实际应用中被广泛批评为存在许多缺陷，包括对客户需求与工程特性之间关系的清晰评估，以及工程特性的非稳健排名。在本文中，我们提出了一种使用双层次犹豫语言术语集（DHHLTS）和公理设计方法来提高经典 QFD 性能的新方法。首先，DHHLTS 用于评估客户要求与工程特性之间的关系。然后，公理化设计理论被扩展为推导出 QFD 中工程特性的优先级。此外，使用最大化共识方法来确定考虑到他们意见不一致的专家的权重。最后，通过一个共享汽车制造商的经验案例进行比较分析，以证明我们提出的 QFD 方法的可行性和有效性。
