Scenario analysis is used for the simulation of the physical protection system (PPS) by considering several credible intrusion and defense scenarios. A practical interaction simulator is developed for the scenario analysis of the PPS. The interaction simulator integrates all discrete subsystems of the PPS to form an intermodulation chain of intrusion-detection-response-interruption. https://www.lightemupsequences.com/flash-pick-ABC-Always-Be-Coding-Poster-top-savings/
