The paper presents an integrated general model of complex technical system, linking its multistate safety model and the model of its operation process including operating environment threats and considering variable at different operation states its safety structures and its components safety parameters. Under the assumption that the system has exponential safety function, the safety characteristics...
This report focuses on the safety analysis in the multistate ageing system after changing the safety state by any of its components, the inside interactions among the remaining components may cause the change of those components’ safety states. As we consider multistate systems, in a local, equal and mixed load sharing model of dependencies. For them, we analyze the safety of a multistate parallel-series...
In this paper we consider dependent Critical Infrastructures (CI) at variable operation conditions and present multistate approach to their safety analysis. The safety of dependent Critical Infrastructures at variable operation conditions is described. The local, equal and mixed load sharing models of dependency subjected to the operation process are introduced. The conditional safety functions at...
The climate-weather change process for a critical infrastructure operating area is considered and its states are introduced. A semi-Markov approach is used to construct a general probabilistic model of this process by defining its basic parameters. Further, the procedure of the climate-weather change process characteristics prediction is proposed.
In the paper, the process of environment degradation at the Baltic Sea area identification is performed. Next, the main characteristics of this process are predicted.
The purpose of the paper is to present the impact model for Global Baltic Network of Critical Infrastructure Networks (GBNCIN), related to its operation process. At first, basic issues regarding the GBNCIN operation at variable conditions have been described. Then, aspects regarding safety of the multistate GBNCIN at Variable operation conditions have been pointed. Finally, safety characteristics...
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...

In the paper, the process of initiating events at the Baltic Sea area identification is performed. Next, the main characteristics of this process are predicted.
An integrated general model of critical infrastructure accident consequences including the process of initiating events, the process of environment threats and the process of environment degradation models is presented. The model is proposed to the evaluation of losses associated with the environment degradation caused by the critical infrastructure accident.
The paper contains data collection of more than 100 sea accidents that have happened at the Baltic Sea area for last three decades. These accidents are classified according to kind and range of the casualty. Moreover, the location and weather parameters during the sea accidents are given.
The main aim of this paper is to present the general safety analytical models of complex multistate technical systems related to their operation processes including operating environment threats. In the case of critical infrastructure, the determination of its safety function and its risk function, which graph corresponds to the fragility curve are defined. Moreover, its mean lifetime up to the exceeding...
The paper presents the theoretical, general approach to safety modelling of operation threats and extreme wather hazards impact on Critical Infrastructures. To achieve this aim, the scheme of the operation and climate-weather influence on CI is presented and described. Furthermore, the basic critical infrastructure safety indicators and IMCISM Model 1 are introduced.
In the paper the safety function of a multistate series network with dependent assets, with dependent subnetworks and with dependent assets of its subnetworks is determined. The multistate series-parallel network with dependent assets of its subnetworks and multistate series-“m out of k” network with dependent assets of its subnetworks is considered. Further the multistate parallel and “m out of n”...
The paper deals with the sea accidents that have occurred at the Baltic Sea port waters for last three decades. For each accident, the climate-weather change process state is fixed to examine the weather hazard influence on this accident. Moreover, the Baltic Sea port waters accidents caused by the extreme weather hazard states are described.
The paper is concerned with an application of the critical infrastructure operation process related to climateweather change model to identification and prediction of this process for the port oil piping transportation system. There are distinguished three different processes for the corresponding piping operating area. Further, using identified parameters of the piping operation process and the piping...
Considering a significant influence of the critical infrastructure operating environment threats on its operation process and safety, more precise and convergent to reality model of the critical infrastructure operation process related to critical infrastructure operating environment threats is built. The method of defining the parameters of this operation process is presented and a new procedure...
The paper presents climate-weather change terminology, selected from the fourth chapter of the report prepared in the scope of the EU-CIRCLE project. This project titled “A pan-European framework for strengthening Critical Infrastructure resilience to climate change – EU-CIRCLE” is realized under the European Union’s Horizon 2020 research and innovation program. The improved terms and definitions...
The paper presents essential critical infrastructure terminology. The terms and definitions have been outlined, in respect to critical infrastructure systems, that are analysed within the scope of the EU-CIRCLE project. Moreover, taxonomy regarding terminology and methodology related to critical infrastructure safety, is presented.
The operation process of the critical infrastructure is considered and its operation states are introduced. The semi-Markov process is used to construct a general probabilistic model of the critical infrastructure operation process. The semi-Markov process is used to construct a general probabilistic model of the climate-weather change process for the critical infrastructure operating area.
