A flexible data driven cooperative simulation environment for digital spacecraft design

Simulation is an important technology in a spacecraft's whole lifecycle. To better facilitate spacecraft modeling and simulation development as well as model integration and reuse, a flexible cooperative modeling and simulation framework which is based on data driven methodology and DEVS (discrete event system specification) is proposed. To verify its effectiveness, a concrete realization of this kind of system was developed and its use in our digital spacecraft design platform indicates that it has good simulation adaptabilities and is suited to improve model composabilities
