Abstract
The new product development process (NPD) is considered to be the key factor of competition among different markets. The identification of a suitable material is an important issue in the conception and improvement of new products. Material selection is seen as an important multi-criteria decision making (MCDM) problem in engineering because of the requirement of considering multiple criteria from different dimensions. Improper material selection may negatively affect the success of a firm. The purpose of this study is to specify the importance of selection attributes, which are considered to evaluate washing liquid that meets the needs of both customers and firms. Then, it objects to choose the most appropriate alternative among various formulations. A fuzzy MCDM methodology based on quality function deployment (QFD), 2-tuple fuzzy linguistic representation, and linguistic hierarchies is presented. QFD is used to incorporate customer requirements into the evaluation process. The 2-tuple fuzzy modeling and linguistic hierarchies are employed to combine multi-granular data given by experts. Finally, the fuzzy COPRAS (Complex Proportional Assessment) method is used to choose the most suitable alternative. The implementation of the developed method is presented by a case study conducted on a detergent manufacturer located in Turkey.
Highlights
New product development (NPD) is considered as a major competitive advantage source for organizations, and understanding the aspects that contribute to new product success is an important managerial issue [1]
Quality function deployment (QFD) is accepted as a significant product improvement tool, quality function deployment (QFD) is a crucial approach that aims to respond to customer requirements (CRs) in developing a new which objects to convert consumer expectations into activities to improve product and services [18]
To accomplish customer requirements while producing a product strictly depends on the QFD is a crucial approach that aims to respond to customer requirements (CRs) in developing a new capability of organizations
Summary
New product development (NPD) is considered as a major competitive advantage source for organizations, and understanding the aspects that contribute to new product success is an important managerial issue [1]. It is based on converting an idea into a visible, touchable entity. Obtaining a new product can be provided by taking the most appropriate decisions at each level of the development process; every step taken by decision makers is very important. The development process starts with producing new ideas and converting these ideas into a proposal.
