Abstract
The purpose of this research is to provide a discussion about the Morphological Matrix tool, a model that is used inside the Conceptual Project Phase of PRODIP Product Development Methodology. In this Phase, the Morphological Matrix is applied in order to design distinct concepts for the desired product. A concept is a cluster of possible solutions principles, which must be aligned to the project requirements, and customer demand. Both are defined during the Informational Project phase. All proposed concepts are evaluated aiming to establish the best concept for the product. Therefore, the Conceptual Phase is performed on main decisions about the product configuration, becoming one of the most critical phases in a Project development.. For complex products, the large number of elementary functions and principles of solution drives to a combinatorial explosion, and the development of all possible concepts becomes impracticable. As a result, this research proposes a methodology to reduce the number of elements into the Morphological Matrix, through the prioritization of elementary functions that are most relevant to the development of the basic physical concept of the product. Thereby it is possible to develop and evaluate basic physical concepts and from them work with the remaining elementary functions. This method was assigned as Lean Morphological Matrix. The prioritization task is ruled by predefined criteria, such as the relative importance of the project requirements, the Quality Function Deployment definitions and the correlation between elementary functions. A case study is performed for the project of a robotic platform for power transformers transportation, a project owned by CELESC - Centrais Elétricas de Santa Catarina S.A. and developed by the Laboratory of Applied Robotics from UFSC. This work contributes to the optimization of the PRODIP methodology and aims to ensure the excellence of a critical phase during a project development, the Conceptual Project phase.
