Design of Component-Oriented Centralized and Distributed-Integrative Runtime Infrastructure of Simulation System

Focusing on specific domains, most traditional simulation systems have features of standalone-centralized running mode, weak interoperability with external simulation systems, difficult reusability of system components. With the technical development of the distributed simulation, the inspiration of developing reusable simulation model components satisfying the needs of simulation systems or environments in the whole simulation domain, as well as endowing the simulation system with the ability of customization, expansion and interoperability by assembling above mentioned components rapidly and conveniently have drawn significant attention within simulation community. The paper addresses a component-oriented centralized and distributed-integrative runtime infrastructure of simulation system. The system has designed the corresponding data distribution, filtering and cache concentration, operating on the subscribing and publishing mechanism, for reducing the redundancy of interactive data between models and improving the running efficiency of the system. It also proposes the simulation service based on the bridge-based design pattern, shielding implementation details between models in the application layer and underlying runtime platforms. The service enables the application of models used not only in traditional standalone centralized simulation systems, but also in distributed simulation system with no editing even compiling. Besides, through using international standard descriptive specification, namely Base Object Model (BOM), for component-oriented simulation models, the system improves the standardization and interoperability of models.
