Distributed Object-Oriented Real-Time Simulation of Ground Transportation Networks with the TMO Structuring Scheme

The TMO (Time-triggered Message-Triggered Object) structuring scheme is aimed at facilitating realtime (RT) distributed software engineering in a form which software engineers in the vast business software field can adapt to with small efforts. It is a syntactically simple and natural but semantically powerful extension of the conventional object structuring approaches. In the course of developing a TMO-structured RT system engineering methodology, an attractively simple approach to parallel and distributed RT simulation has been produced. Also, we recently implemented a TMO execution engine based on the Windows NT platform and named it TMOSM/NT. As an effort for validation of both the execution engine TMOSM/NT and the TMOstructured RT simulation approach, a freeway automobile traffic simulator named distributed object-oriented freeway simulator (DOFS), has been constructed. In this paper, the design techniques and tools applied in development of DOFS are discussed.
