Content available Optimization of Critical Infrastrucutre operation and Safety With Considering Climate-Weather Change Impact - Minimizing Operation Cost

EN
The general model of a critical infrastructure changing its safety structure, its components safety parameters and its operation cost during the variable operation process and linear programming are applied to optimize the critical infrastructure operation process in order to get the critical infrastructure operation cost optimal value. The optimization problem allowing to find the optimal values of the transient probabilities of the critical infrastructure operation process at the particular operation states that minimize the critical infrastructure operation cost mean value in the safety states subset not worse than a critical safety state is presented. The optimization of operation cost of the critical infrastructure is proposed with considering climate-weather change process influence on the system safety.

EN
The method based on the results of the joint model linking a semi-Markov modelling of the critical infrastructure operation process with a multistate approach to critical infrastructure safety and linear programming are proposed to the critical infrastructure operation and safety optimization. This method determining the optimal values of limit transient probabilities at the critical infrastructure operation states that maximize the critical infrastructure safety lifetime in the safety state subsets is proposed.

Content available Identification and prediction of port oil piping transportation system operation process related to climate-weather change

EN
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 operating area climate-weather change processes, there are determined the unknown parameters of those processes. Namely, there are determined the probabilities of the processes staying at the initial states, the probabilities of the transitions between the states and the mean values of the processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the piping operation process related to climate-weather change processes at the distinguished operating area.

The paper is concerned with an application of the critical infrastructure operation process related to climate-weather change model to identification and prediction of this process for maritime ferry. There are distinguished four different processes for the corresponding ferry operating area. Further, using identified parameters of the ferry operation process and the ferry operating area climate-weather change processes, there are determined the unknown parameters of those processes. Namely, there are determined the probabilities of the processes staying at the initial states, the probabilities of the transitions between the states and the mean values of the processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the ferry operation process related to climate-weather change processes at the distinguished operating area.

Introductory general approach to EU-CIRCLE project taxonomy and methodology is presented. National and international critical infrastructure protection overview is performed. The critical infrastructure protection legal frames in Poland, the institutions responsible for them and their duties are presented in details. A general approach to and a scheme of operation and climate-weather change influence on critical infrastructure safety and critical infrastructure accident consequences modelling is proposed as well.

EN
Considering a significant influence of the critical infrastructure operating environment threats on its operation process and safety, based on semi-Markov processes theory, a 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 new procedures of their determining in the case when the critical infrastructure operating threats are not explicit separated in this process are proposed.

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.
