Abstract :
This paper considers several components in the architecture and design of systems to discriminate conditions and fuse the data. It focuses on the problems of missing detections and reducing the possibility of generating false positive alarms. It uses a case study of a protective system that detects arcing faults in power switchboards on board ships. The results in this paper can be used in many systems that must monitor and detect hazardous events both accurately and consistently while minimizing false positive alarms that can cause harmful results. Examples include power plants, hospitals, computer installations, web servers, military sensors that detect enemy vehicles, aircraft engine monitoring, and telecommunications.
