Conception collaborative et aide à la décision pour les systèmes mécatroniques : Établissement d’un cadre formel.

Abstract : Mechatronic systems are defined as a synergistic integration of mechanical, electronics and computer supported by control strategies. This variety of disciplines makes the development task complex and challenging. To address this complexity, the different engineering disciplines need to collaborate dynamically to exchange knowledge and ensure the development of a coherent and robust system.However, only knowledge that contribute to achieving the project objectives should be exchanged. Such knowledge is used to solve problems and the risk of losing it is considered important. We call the most important knowledge "crucial knowledge". During knowledge sharing, interdisciplinary conflicts are likely to occur and must be resolved to obtain a coherent system. Furthermore, different design alternatives or architectures for the same system are proposed. This implies the need to evaluate these alternatives according to specific criteria in order to find the architecture that best meets the requirements. Considereing the multidisciplinary nature of mechatronic systems and the heterogeneity of the expert models involved in the collaboration, a formal framework becomes necessary in order to unify and formalize these expert models. This formalization will allow the crucial knowledge identification and conflict management.In this context, category theory (CT) is likely to be an effective formalization framework. This theory has recently been the subject of much work in the field of collaborative design and systems engineering. Motivated by the category theory formalism, we propose a new approach to harmonize collaboration during mechatronic design based on fine granularity knowledge. Our approach, called "Category Theory-based Collaborative Design and Decision-making" (CaTCoDD), allows the identification of crucial knowledge based on category theory. This theory is used for conflict detection and resolution. The proposed approach also deals with the evaluation of different system architectures. Finally, a demonstrator is implemented on an electromechanical actuator (EMA) of an aileron in order to validate our approach.
