In the era of renewable energy, offshore wind farms play a very important role. The number of such installations in Europe is increasing rapidly. With the growing capacity of wind turbines installed in these farms (3, 5, 10 MW), the profitability of this type of energy systems plays an increasing role. The number of wind energy turbines installed at offshore wind farms is growing constantly as well. Once installed, the power plants must be under constant technical supervision, with reliability of electronic communication systems being a particularly important aspect in the operation of offshore wind farms. Considerations focusing on this subject form the very core of this paper. After an introduction to offshore wind farms, the following aspects will be discussed: redundant topologies, e.g. multiple HiPERRings, redundant switches and routers within the backbone networks, redundancy of the transmission media used, alternative transmission technologies, e.g. WLANs (IEEE 802.11h, IEEE 802.11g). Finally, requirements applicable to reliable electronic communication systems used in offshore wind farms will be formulated.

Intelligent transportation systems mostly operate on information exchange principle between vehicles and roadside infrastructure. They are commonly regarded as a base technology for persistent diminution of road accidents and traffic efficiency increase. However, intelligent transportation systems can also be used at all levels of transportation systems as a basis for stable development of cities, enterprises, regions, states, continents. According to the research, the existing intelligent transportation systems not only provide the considerable reduction of greenhouse gases emissions, fuel saving, time of travel cutting, but they don’t marginalize citizens’ mobility as well. Thus, the further development and introduction of modern transportation innovative technologies will allow to guarantee the power- and resources efficiency and, therefore, the sustainable development of the whole society.

The work describes the impact the reliability of the information quality IQ for information and communication systems. One of the components of IQ is the reliability properties such as relativity, accuracy, timeliness, completeness, consistency, adequacy, accessibility, credibility, congruence. Each of these components of IQ is independent and to properly estimate the value of IQ, use one of the methods of modeling uncertainty. In this article, we used a hybrid method that has been developed jointly by one of the authors. This method is based on the mathematical theory of evidence know as Dempstera-Shafera (DS) theory and serial links of dependent hybrid named IQ (hyb).

W pracy opisano wpływ niezawodności na jakoś informacji IQ (ang. – Information Quality) przesyłanych w systemach teleinformatycznych. Jedną ze składowych IQ jest niezawodność obok takich właściwości jak relatywność, dokładność, aktualność, kompletność, spójność, odpowiedniość, dostępność, wiarygodność, przystawalność. Każda z tych składowych IQ jest niezależna i aby poprawnie oszacować wartość IQ należy użyć jednej z metod modelowanie niepewności. W artykule tym zastosowano metodę hybrydową opracowaną wspólnie przez jednego z autorów artykułu. Metoda ta opiera się na ewidencji matematycznej znanej jako teoria Dempstera-Shafera (DS) oraz szeregowych powiązaniach zależnych nazwanych hybrydowymi IQ(hyb).
