A Fuzzy Decision system for New Product Specification Forecast

New product development (NPD) requires considering multiple criteria under a hierarchical structure. The evaluation process often involves uncertainty and fuzziness in both the relationships between criteria and the judgments of evaluators. Quality function deployment (QFD) aims to facilitate the NPD process from product conceptualization to production requirements. New Product Specification Forecast System (NPSFS) support product development and used from first matrix of QFD. A case study of a scale producer firm to select the Specification of new product based on data collected from designed questionnaires is given which includes identification & determination of customers’ needs, while looking for technical and engineering characteristics related to their needs. The results are then used to construct houses of quality for QFD, which is incorporated by fuzzy AHP. It is concluded that the proposed decision support system by fuzzy QFD can be used as a powerful tool to select the most suitable specification for new products to satisfy customer's needs.
