A hybrid QFD-based approach in addressing supplier selection problem in product improvement process

Abstract

This paper is about creating a hybrid QFD-based approach in which the best supplier is selected considering changing customer needs.In most previous studies employing a QFD approach, the possibility of changing customer needs is ignored.On the other hand, supplier selection is a challenging problem that could have been addressed by such a QFD.This paper attempts to create a hybrid QFD-based approach in which the internal relations between the elements are considered.It connects the new QFD to suppliers' qualifications to create a hybrid supplier selection process.The best suppliers are selected based on the priorities of customer needs for each level of the product improvement plan.When a product is to be developed, the proposed methodology seems to create an efficient solution for supplier selection problem with respect to quality factors.
