Abstract
The development of a mechatronic system implies a global control of the business process through all its life cycle. In this multi-business context, one of the main difficulties is to manage globally the different evolutions of business components. It is necessary to keep the coherence and the information integrity as well as to allow a real collaboration between the different business designers throughout the life cycle of the product. For this need, Product Lifecycle Management (PLM) systems seem the most appropriate, however they do not allow a global integration of the different business domains. The object of this paper is to present a global approach for the integration of mechatronic systems into a PLM system using a specific modelling. This modelling is based on the life cycle characterisation and the use of System Modelling Language (SysML).
