The approach addresses selected technical and organization aspects of risk mitigation in the oil port installations with regard to functional safety and security requirements specified in standards IEC 61508, IEC 61511 and IEC 62443. The procedure for functional safety management includes the hazard identification, risk analysis and assessment, specification of overall safety requirements and definition...
The paper presents the analysis and discussion of gender recognition based on human face picture. The research combines different features selection techniques with the set of softcomputing classifiers. We are looking for not very complicated, fast and sensitive approach to create the theoretical basis for real safety systems where the correct “on-line” gender recognition is necessary. We start from...
Cognitive engineering is considered nowadays as interesting multidisciplinary domain that focuses on improving the relations between humans and the systems that are supervised and operated. The industrial automation and control systems (IACS) in hazardous plants are increasingly computerized and perform various safety functions. These are designed and implemented according to the functional safety...
The paper is proposing a methodology for assessing the time-criticality in the scope of a crisis resulting from a cascade of disruptions of a set of Critical Infrastructures (CIs). The success of the management of the crisis depends on taking the good decisions and undertaking the corresponding actions at the good timing. Identifying time intervals for decisions and actions requires dynamic models...
Probabilistic model of a system composed of a main component, an emergency backup component and the automatic switch are discussed in this paper. The reliability model is semi-Markov process describing evolution of the system. Conditional time to failure of the system is represented by a random variable denoting the first passage time of the process from the given state to the subset of states. The...
Weather-related hazards are among the most frequent causes for disturbances of critical infrastructures. Flooding, tsunamis and sea level rise are examples of major threats to all types of nuclear facilities located at the seaside or at rivers. We report about exemplary investigations concerning weather-related hazards for the North Sea and the Baltic Sea. Climate change is expected to increase the...
In the analysis of the operation of critical infrastructure systems it is important to perform the analysis of the safety of the operation. The daily operation of such systems is inherently associated with the occurrence of various types of random undesirable events. Therefore, in the paper the methods used in the analysis of the risk of threats in critical infrastructure systems within the Baltic...
In the paper the issues connected with failure risk analysis related to the functioning of this system were presented. In the analysis of water supply system it is important to assess the safety of its operation, both from the producer and the consumer point of view. The paper presents the method of analysis of consumers acceptance of water costs that companies bear for the risk reduction. The proposed...
The paper presents reliability analysis of CLARIN-PL Centre of Language Technology (CLT). The CLT is a Polish part of the language technology infrastructure developed by CLARIN project. The main goal of which is to support researchers in humanities and social sciences. The infrastructure is a complex computer system that enables combining language tools with language resources into processing chains...
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 nuclear accidents of Fukushima in March 2011 have indicated the significance of external hazards for nuclear installations safety. One lesson learned from post-Fukushima investigations worldwide is that the operating experience from external hazards, even if these did not pose any significant harm to the affected plant, do represent important precursors, which should be taken into account in deterministic...
In contemporary computer systems security issues are very important for both safety and reliability reasons thus application of appropriate cryptographic methods is a necessity in system design and maintenance. This paper deals with one such method – BLAKE hash function – and investigates its implementation in hardware. The algorithm was a candidate proposed for the SHA-3 contest and, although it...
This article addresses selected methodological aspects of a process based management system based on analysis of hazards and threats and risk evaluation for an oil port infrastructure in context of insurance. The oil port terminal is regarded as important system of the critical infrastructure that require careful system oriented approach to deal with integrated aspects of environmental, safety and...
The main aim of the paper is to present resilience terminology and methodology. The terms and definitions have been outlined alphabetically, with accordance to notations for resilience, risk, response, business continuity and communications, that are analysed within the scope of the EU-CIRCLE project. Moreover, the resilience indicators are defined and presented as the basic methodology in the field...
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...
The paper is concerned with the problem of safe trajectory planning for approaching during emergency STS (Ship to Ship) transfer operation with oil spill. The safe trajectory means that the way points does not cross in the area of the environment with the static and dynamic obstacles and at the same time satisfies ship's stopping and speed deceleration performance. The evolutionary path planning algorithm...
The approach for probabilistic analysis of the remote monitoring systems (RMS) of critical infrastructure safety (CIS) is proposed. It allows to estimate the reliability and timeliness of information producing, the completeness, validity and confidentiality of the RMS information. In application to composed and integrated CIS with RMS and without RMS the earlier models, developed by authors, are used...
This paper presents a probabilistic model of hazard-related interdependence between the operations carried out in the ports of the Baltic Sea region and in their neighborhoods. Each single operation, considered w.r.t. its hazardous aspect, will be defined as a point process consisting of undesired events (emergencies and/or accidents). Thus, the interdependence between these processes can be regarded...
For a meaningful and efficient probabilistic risk analysis of external hazards and event combinations involving such hazards those hazards with significant risk potential need to be identified and considered for detailed anal-yses. Such a site and plant specific screening approach for external and internal hazards based on a hazards library covering all types of hazards is under development at GRS...
