Integrated Impact Model on Critical Infrastructure Safety Related to Its Operation Process Including Operating Environment Threat and Climate-Weather Change Process Including Extreme Weather

The paper presents the general safety analytical model of a complex technical system under the influence of the operation process including its operating environment threats related to climate-weather change process, The system operation process including environment threats under influence of climate-weather variable conditions is defined. Moreover, the safety model of multistate systems at variable conditions related to operating environment threats and extreme weather hazards is proposed. The conditional safety functions at the operation process including operating environment threats and related to climate-weather change process particular states, the unconditional safety function and the risk function of the complex system at changing in time operation and climate-weather conditions and other, practically significant, critical infrastructure safety indices are defined. Furthermore, the same safety indicators are defined for exponential systems.
