Issues of Intruder Analytical Model Applicability for Evaluating an Efficiency of Security Systems
Get PDFPhysical protection system (PPS) is created at a nuclear object to prevent unauthorized acts regarding to nuclear materials, nuclear installations, points of storage of nuclear materials and other items under physical protection. The ability of the PPS to prevent unauthorized actions of intruder was adopted as the main criterion for evaluating the efficiency of the physical protection system. The article considers the possibility of creation of the intruder analytical model to determine time indicators of overcoming boundaries of protection of nuclear object by an intruder with set features
