Conceptual design is a crucial system lifecycle stage, but systematic methods for conceptual design evaluation are not well-developed and existing approaches are not satisfactory. In this work we have developed and assessed an advanced simulation environment that can serve conceptual design evaluation purposes using Object-Process Methodology (OPM). The simulation exploits the advantages of OPM modeling language: its integration of the structural and behavioral aspects of the system in a single type of diagram and the hierarchical organization of the model diagrams. The simulation of the system model is instrumental in understanding and exploring the behavioral aspects of the system and uncovering logical and conceptual problems such as incorrect control flow and missing structural relations among objects. The latter is achieved via an intuitive user interface and a host of debugging capabilities, including “lifespan” and “Debug Info” components. Using these components one can explore the state of any OPM entity and be aware of a variety of potential problems that are manifested during the simulation process. Serialization of the simulation execution traces in an XML format is implemented for further reproduction and possible various analyses. The work contains a comprehensive overview of the OPM based simulation project, including background, specification, architecture, implementation, evaluation, and open issues.
