Integrated modeling methodologies and languages

Abstract

Two1 state-of-the-art languages being used in the field of integrated modeling and management of systems are OMG Systems Modeling Language (SysML) and Object-Process Methodology (OPM). SysML is based on UML 2, a de-facto standard in software engineering. OPM is chartered as ISO/PAS 19450 for system and process modeling. Aspects of these two diverse modeling methodologies have been comparatively analyzed and examined. This paper points to yet another approach that takes a methodology oriented to flow of things to provide an underlying conceptual model on which to construct a fundamental representation of the information or physical system. Adopting a similar analysis technique of comparing SysML and OPM, we examine features of a flow of things orientation based on a concrete sample problem. To demonstrate the feasibility of this methodology in a real environment, we present a case study of an actual IT department of a government ministry, and the results point to the viability of the approach as a foundation for modeling and management of systems.
