The world shipbuilding industry has evolved considerably in recent years. Some quantitative and qualitative factors influence the competitiveness of naval production units, the shipyards. The development of shipbuilding processes depends on the evolution of manufacturing techniques, techniques of planning, organization, control of processes and external environment. Factors that allow a shipbuilding organization to evolve in performance. In general, in the performance, quantitative variables are analyzed through mathematical and linear models. But in relation to the qualitative variables, due to its subjectivity because it deals with human perceptions. It is not common for organizations to work on the performance of these factors, which are equally critical to achieving competitiveness. This is the objective of the research, to analyze qualitative factors in shipbuilding in the Brazilian case. The chosen ones that compose the proposed model are technology and industrial location. In this context, this research presents a prioritization evaluation model of qualitative performance variables. Which presents the original treatment by the fuzzy sets of qualitative critical factors expressed in linguistic terms by specialists working in the Brazilian sector. To generate the prioritization of these factors that also influence the best performance of a yard. The model was applied at a specific shipyard. The results showed that the proposed fuzzy model is a good tool for the evaluation of qualitative performance factors to identify the distance of the unit from the specialist prioritization of the model.
