The design activity is the transformation of functional requirements into design parameters. This article presents a structuring method for the design problem exploiting existent and mastered knowledge. The proposed energy analysis leads to the structural definition of the product and the definition of a basis of functions and components. This approach allows efficient implementation of optimization models in preliminary design.

PAILHES, Jérôme; SALLAOU, Mohammed; NADEAU, Jean-Pierre; FADEL, Georges Michel (American Society of Mechanical Engineers, 2011)This paper presents an energy based approach to functional decomposition that is applicable to the top down design (system to subsystems to components) of mechanical systems. The paper shows that the main functions of ...
AGUDELO, Lina-María; MEJÍA-GUTIÉRREZ, Ricardo; NADEAU, Jean-Pierre; PAILHES, Jérôme (2014)In a design process the product is decomposed into systems along the disciplinary lines. Each stage has its own goals and constraints that must be satisfied and has control over a subset of design variables that describe ...
CALLE-ESCOBAR, Manuela; MEJÍA-GUTIÉRREZ, Ricardo; NADEAU, Jean-Pierre; PAILHES, Jérôme (2014)This article explores the applicability of heuristic rules into the decision-making processes involved in design practices. For this purpose, the research focuses on the development of a methodology that seeks to facilitate ...

The fuzzy logic has been useful to compare products ...
GIRARDEAU, Julian; PAILHES, Jérôme; SEBASTIAN, Patrick; PARDO, Frédéric; NADEAU, Jean-Pierre (ASME, 2013)Designing high performance cooling systems suitable for preserving the service lifetime of nozzle guide vanes of turboshaft engines leads to significant aerodynamic losses. These losses jeopardize the performance of the ...
