Lifecycle management of product information is a recent paradigm. It is essential at knowledge driven integration of model generation processes in virtual engineering. In the centre of virtual engineering environment complex product model includes representations for lifecycle of product. Recently, generic product models apply built in active knowledge at self generation of their instances. Widespread development of multidisciplinary products generated demand for higher level abstraction than representation of physically existing objects in product model. For this purpose, product models in leading product lifecycle management (PLM) systems apply the requirements, functions, logical, and physical (RFLP) structure from systems engineering (SE). Elements on the functions and logical levels of RFLP structure have capability for product behavior representation. Finding solutions for the generation of RFLP structure elements is new challenging task for researchers. One of the latest researches at the Laboratory of Intelligent Engineering Systems (LIES) attempted answer the question that how design intent can be applied for RFLP structure element generation with special attention to behavior representation. Result of this research is the Multilevel Abstraction Based Self Adaptive Definition (MAAD) modeling method and model structure. MAAD is considered as a possible solution for higher level abstraction based generation of RFLP elements. In this way, organic integration of MAAD structure in knowledge driven PLM model structure is very important. Although MAAD structure is devoted as application oriented user extension to industrially applied PLM models, it may gain general application in product modeling. Future research is planned to ensure its implementation and practical application in representative PLM environment. In this paper, the MAAD method and model structure are introduced, explained, analyzed, and discussed.
