Intelligent alarm classification based on DSmT

In this paper the critical issue of alarms´ classification and prioritization (in terms of degree of danger) is considered and realized on the base of Proportional Conflict Redistribution rule no.5, defined in Dezert-Smarandache Theory of plausible and paradoxical reasoning. The results obtained show the strong ability of this rule to take care in a coherent and stable way for the evolution of all possible degrees of danger, relating to a set of a priori defined, out of the ordinary dangerous directions. A comparison with Dempster´s rule performance is also provided. Dempster´s rule shows weakness in resolving the cases examined. In Emergency case Dempster´s rule does not respond to the level of conflicts between sound sources, leading that way to ungrounded decisions. In case of lowest danger´s priority (perturbed Warning mode), Dempster´s rule could cause a false alarm and can deflect the attention from the existing real dangerous source by assigning a wrong steering direction to the surveillance camera.
