The Quality Function Deployment (QFD) approach integrated with multicriteria decision-support methods has been widely applied to development of new product, particularly with the support of fuzzy logic. The objective of this dissertation is to propose a conceptual model based on the fuzzy ANP-QFD approach to define and prioritize project requirements of new defense products. The research can be considered descriptive, applied, and methodological. Based on the results of the bibliographic and documentary review on the central themes of the research, a conceptual model was developed to determine and prioritize project requirements of new defense products, seeking to fill gaps identified during the literature review covering the period of 1987-2017. The applicability of the model was demonstrated by an empirical case study having as experimental context the Project COBRA 2020, a strategic initiative of the Brazilian Army. For this study, one of new products to be developed within this Project was selected – a monocle of thermal vision. The main contribution of the research is a model for determining and prioritizing project requirements of new defense products, which considers the complexity, subjectivity, and uncertainty as inherent characteristics to the design of new defense products. The research findings could be replicated in other projects of new defense products - at the Army Technological Center - CTEx - and other military institutions dealing with research, development and innovation (RDandI) activities in Brazil and abroad.
