DECISION SUPPORT FOR PHYSICAL PROTECTION SYSTEMS USING ROUTE-LEVEL METRICS AND SIMULATION-BASED EVALUATION

This article proposes a quantitative decision-support framework for improving the effectiveness of systematic physical protection systems at critical infrastructure and special-purpose facilities with heterogeneous route architectures. The study is based on the premise that physical protection should be treated not merely as the accumulation of technical means, but as a route-sensitive management problem that explicitly accounts for adversary movement options, perimeter heterogeneity, and the integrated functioning of detection, delay, and response elements. The primary effectiveness criterion is defined as the route-level probability that the facility remains in a safe state, which enables the identification…
