1. Introduction QFD usually requires four matrices. These are product planning, part planning, process planning, and production/operation planning matrices. In this paper, fuzzy set theory is used to present a multiple objective decision framework that incorporates imprecise and subjective information inherent in the QFD planning process. 國立雲林科技大學 業 程與管理所 12/31/2021

2. Literature review Literature Integration History • The late 1960 s-QFD was first conceptualized. • 1972 -QFD was implemented at the Kobe shipyards of Mitsubishi Heavy Industries Ltd. QFD Method • AHP • Fuzzy set theory • Linear programming model Today In today’s global and competitive marketplace, the HOQ is a key strategic tool to aid companies in developing products that satisfy customer needs. 國立雲林科技大學 業 程與管理所 12/31/2021

3. Fuzzy multiple objective decision framework There exist objectives to be maximized denoted by Zk and the ones to be minimized represented by Ws. Employing these definitions, the model formulation is as follows 國立雲林科技大學 業 程與管理所 12/31/2021

The importance degree of each objective can be incorporated into the formulation using fuzzy priorities. The general representation for the membership function corresponding to the importance degrees can be denoted as 國立雲林科技大學 業 程與管理所 12/31/2021

5. Conclusions The fuzzy multiple objective programming framework presented in this paper for prioritizing design requirements extends the single objective viewpoint of maximizing customer satisfaction by considering the company’s other design related objectives, and thus, precludes an unreasonable QFD planning in practice. 國立雲林科技大學 業 程與管理所 12/31/2021
