Potential Hazardous Elements Mining for Task Synthesis Safety Analysis in IMA System

Integrated avionics system supports the optimized integration organizing process which is based on task synthesis, function fusion and physical integration. Task synthesis achieves system task organization optimization and improves task system application efficiency based on application requirements of aircraft mission system. Although it can improve task efficiency, it meanwhile causes such problems that it is hard to confirm failure state and diagnose failure constitution. Therefore, as application layer, task synthesis safety is very significant for integrated avionics system. In this paper, we propose a new differential bicluster mining algorithm: DFCluster, to mine potential hazardous elements or initialing mechanism in two function-resource matrixes for task synthesis safety analysis. In order to mine efficiently, we design several pruning techniques for generating maximal biclusters without candidate maintenance. We use a simple experiment to show how to use our proposed algorithm to help system safety analysis. (Abstract)
