Abstract:

Surveillance system is widely used today to enhance the security level of the protected area. Reliability of the entire surveillance system is a critical issue since the breakdown of such system would leave the monitoring area unobserved and encountered much higher risk under the attacks. This paper presents a dual stochastic-process model for predicting the reliability of surveillance systems consisting of many subsystems (units) with considerations of the environmental factors, skill of intruder to avoid detection, the intrusion/incident arrival process and subsystem failure process. Several numerical examples are presented to illustrate the proposed model.
