This paper introduces a new method as contribution to product definition on logical, functional, and requirements levels of abstraction in order to assure conceptual model of multidisciplinary product and achieve better physical level modeling. This method is result in a long term research program at the Laboratory of Intelligent Engineering Systems (LIES), Óbuda University. The main concept is establishing chain of request, behavior, contextual connection, and model entity generation action content representations on the way to define physical objects in product model. The main subject of this paper is analysis and discussion of driving structure for extended self instantiation in the above complex model. This structure is based on results in the formerly developed request, behavior, action, and context (RBAC) structure and is intended to utilize at development of the LIES initiative, behavior, context, and action (IBCA) structure.
