Multilevel abstraction based self control method for industrial PLM model

Abstract

Challenges in product definition and application related engineering stimulate quick development of product lifecycle management (PLM) systems. The main directions of this development are adaptive definition of product, extending PLM model definitions to higher level of abstraction, and automation of the model generation by including model definition activities in product model. Joining to the above efforts, this paper introduces modeling concept and methodology for better communication between engineers and the currently applied requirement, functional, logical, and physical (RFLP) abstraction based PLM models. This work was grounded by previous research results in knowledge based adaptive modeling methods and supported by the Laboratory of Intelligent Engineering Systems (LIES) at the University of Óbuda. After introduction of currently applied abstraction levels in PLM models, modified levels of abstraction are proposed in this paper. Following this, the method Multilevel Abstraction Based Self Adaptive Definition (MAAD) is introduced by the organized main contextual connections in the MAAD and the MAAD adaptive product definition process.
