Modeling and Analysis of Requests, Behaviors, and Actions for RFLP Structure

Organization of product information in requirements, functional, logical, and physical (RFLP) model structure is recent result on the long way from conventional documents to comprehensive and consistent virtual environments in engineering. Recent virtual engineering environments utilize generic product model which is self adaptive in order to assure its automatic instantiation in case of changed circumstances and events. The RFLP structure applies known ideas from requirements engineering (RE) and systems (SE) engineering and provides high level abstraction for multidisciplinary definition of product concepts and features. At the same time, advanced features of RFLP structured product model allows for wide applications including fundamental and product related research and development from small experiments on few objects to definition of complete products. Actual problem is to replace the current human dialogue based RFLP structure element definition by multiple human requests driven RFLP structure element generation. As a contribution to solve this problem, paper introduces the request, behavior, and actions (RBA) knowledge content structure. RBA structure was tailored in accordance with knowledge demand at RFLP structure element generation and assured consideration of human intent through contextual chain of content elements from content dialogue or import to RFLP element generation. RBA structure concentrates on modeling of request content driven product behavior. Functional, logical and physical product structures are driven by behavior definitions. RBA structure is recent result at the Laboratory of Intelligent Engineering Systems (LIES, Óbuda University).
