Research on HLA-based simulation data collection and analysis system

The distributed simulation standard,HLA,brings up many new challenges for data collection and analysis because of its wide applicability,flexibility and user-customization.Based on the analysis of existing tools' deficiencies and new requirements,an HLA-based simulation data collection and analysis system,HIT-DCAS,is designed and developed,which could collect simulation state information and meets the requirements of the real-time query,situation display,post-action review,validity analysis and result analysis.Then the scheduling method is discussed in detail,which is used in simulation data collection.And an analysis method of simulation run validity is proposed through constructing the state matrix.Finally,the HIT-DCAS is validated by the experiment.
