Flexible Simulation Data Collection and Replay Tool

Data collection and replay (DC&R) of simulation systems are useful for a number of purposes including debugging, evaluation, after action review, demonstrations and analysis. In an HLA environment the data collection and replay procedures become more complicated due to the features designed to improve interoperability and reuse. In the paper, the architectures of HLA DC&R are summarized; taking different systems, various users, automation and intelligence into consideration, the flexible DC&R tool, HIT-DC&R, is designed and developed to meet new requirements; the key issues including storage and index strategy, distributed replay synchronization, dynamic scheduling, automated replay are presented, and the solutions are discussed in details. In the end, the recommendation on the future direction is put forward
