Consideration of the reconfigurable aspect in evaluating predictive reliability of mechatronic system

Abstract

More than a multi-technology fusion, mechatronic systems are becoming more and more complex, these systems can be reconfigured with changes in the environment and states of the functional units, evaluating and improving the reliability of mechatronic system requires to take into account the reconfigurable aspect. This point has become a major challenge for reliability engineers during the design phase. Therefore their dysfunctional modeling is very difficult. This communication presents an original proposed methodology for evaluating the reliability of mechatronic system with taking account the reconfigurable aspect. This reliability model integrates the change of the configuration related to the external and internal conditions.
