An effective interaction control mechanism with minor step for multidisciplinary collaborative simulation system

Collaborative simulation is an important technology for complex engineering systems. The challenges of collaborative simulation are especially in model integration, interaction control and time advancement where a variety of collaborative disciplinary subsystems for time-synchronized running are handled dynamically in a distributed environment. In this paper, the formulized paradigm of multidisciplinary collaborative simulation for complex engineering systems is principally analyzed. A strategy for collaborative simulation in a distributed environment is proposed to implement an integrated framework leveraging HLA and web services technology. A minor-step-based interaction algorithm is presented to improve the precision. The interaction model definition and I/O data processing mechanism of the adaptor is studied. The prototype system and case studies are developed to demonstrate the effectiveness of this approach.
