Supply chain design through QFD-based optimization

Abstract

Purpose – The purpose of this paper is to demonstrate a methodology to design a supply chain with a view to achieve a strategic fit between competitive and supply chain strategies. Design/methodology/approach – Quality function deployment (QFD)-based optimization methodology is employed to design a supply chain for a product through aligning the competitive and supply chain strategies. Normal boundary intersection (NBI) method is adopted to obtain optimal weights of the supply chain design objectives. Weighted additive model is developed for multi-objective optimization. Utility-based attribute function, which structure the relationship between the elements of competitive and supply chain strategies is established. The utility functions and the information contained in the House of Quality (HOQ) of QFD are used to define the supply chain performance (SCP). Findings – SCP index is computed using the set of supply chain design objectives obtained by solving the weighted additive model. On the basis of SCP index, the supply chain activities are planned accordingly. An illustrative example is presented in this paper to describe the QFD-based optimization methodology for designing a supply chain. Originality/value – QFD-based optimization is a novel approach to design a supply chain with a focus on aligning competitive and supply chain strategies.

Design of breastfeeding chairs for maternity rooms based on Kano-AHP-QFD: User requirement-driven design approach

“…Using the QFD theory, the House of Quality model is constructed based on the conversion result of the user requirement-design function [ 48 ]. A panel of specialists comprising five designers with experience in breastfeeding chair design and three engineers with more than five years of production experience in mother-and-child products was tasked with conducting a correlation evaluation.…”

Fuzzy DEMATEL-QFD for Designing Supply Chain of Shipbuilding Materials Based on Flexible Strategies

“…In the context of defining green supply chain standards based on QFD, Haiyun [62] combine the fuzzy DEMATEL and fuzzy multi-objective optimization model to obtain the ranking of green supply chain innovation strategies. Moreover, Prasad and Subbaiah [63] match the competitive strategy with the supply chain strategy in a supply chain design based on QFD.…”

Revising the interrelationship matrix of house of quality by the Kano model

“…The first phase of quality function deployment (QFD), product planning, is also called house of quality (HoQ) (Ertugrul Karasak and Dursun, 2014; John et al , 2014; Durga Prasad et al , 2014; Iqbal et al , 2014). In HoQ, product design characteristics (PDCs) are prioritized based on customer requirements (CRs).…”
