Safety analysis of critical infrastructure impacted by operation and climate-weather changes - theoretical backgrounds

The methodology and general approach to critical infrastructure safety and resilience analysis is proposed. The principles of multistate approach to critical infrastructure safety analysis are introduced. There are introduced the notions of critical infrastructure basic safety indicators like, the critical infrastructure safety function, the critical infrastructure risk function and the critical infrastructure fragility curve. The critical infrastructure safety and resilience indicators are proposed to be obtained using probabilistic approach to modelling of operation threats and extreme weather hazard impacts on its assets safety. There are proposed safety and resilience indicators, crucial for operators and users of the critical infrastructure, defined as a complex system in its operating environment. The safety of a critical infrastructure free of any outside impacts is discussed and modelled. The safety indicators of this critical infrastructure are defined. The safety of critical infrastructure impacted by its operation process is considered. The critical infrastructure operation process and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure related to the operation process impact are proposed. The safety of critical infrastructure impacted by the climate-weather change process at its operating area is considered. The climate-weather change process at the critical infrastructure operating area and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure related to the climate-weather change process at its operating area impact are proposed. The safety of critical infrastructure impacted by its operation process and climate-weather change process at its operating area is considered. The critical infrastructure operation process related to climate-weather change process at its operating area and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure impacted by the operation process related to climate-weather change process are proposed. Real critical infrastructures and their assets impacted by their operation processes related to climate-weather change process at their operating area are suggested to be examined and their safety and resilience indicators are proposed to be determined by the proposed methods.
