Risk-based approach to design and maintenance of alarm systems for security

Abstract

Risk-based approaches to the design and maintenance of an alarm system for security are presented. Based on the values of its sensors, the security alarm system identifies all enemies entering the system. In the design problem, a simple systematic method is given to obtain the minimal combination of sensors that can identify all enemies with the minimal error risk. In the maintenance problem, a simple decision criterion is given to determine the maintenance time, considering the loss caused by failure of the security alarm system and unnecessary protective actions.<>
