Integrated Impact Model on Critical Infrastructure Safety Related to Its Operation Process and Climate-Weather Change Process

Vol. 8, No. 4

The main aim of the paper is to define the operation and climate change influence on the safety of a critical infrastructure considered as a complex system in its operating environment. As the result, a general safety analytical model of a complex technical system under the influence of the operation process related to climateweather change process is proposed. Further, the conditional safety functions at the operation process related to climate-weather change process, the unconditional safety function and the risk function of the complex system at changing in time operation and climate-weather conditions are defined. Moreover, the mean lifetime up to the exceeding a critical safety state, the moment when the risk function value exceeds the acceptable safety level, the intensities of ageing of the critical infrastructure and its components and the coefficients of the operation and climate-weather impact on the critical infrastructure and its components intensities of ageing are proposed as the other significant safety indices for any critical infrastructure.
