MODEL FOR RELIABILITY, AVAILABILITY AND SAFETY OF THE CONTROL CENTRES OF VESSEL TRAFFIC MANAGEMENT AND INFORMATION SYSTEMS

摘要

The quality of Vessel Traffic Management and Information Systems depends on the quality of all subsystems, in particular the quality of control centres. The most commonly used quantitative indicators of the control centres' quality are: reliability, availability, safety, and system failure. Therefore, a block diagram of reliability and the model for reliability / availability (Markov model) have been created in this paper and a detailed analysis and calculation of the quantitative indicators of critical components (servers) of the control centre have been performed. The quality functioning of the control centres will enable gathering, processing, storing and dissemination of timely, safe, and reliable data and information to the services in charge of monitoring and management of maritime traffic.%Kvaliteta sustava za nadzor i upravljanje pomorskim prometom ovisi o kvaliteti svih podsustava, posebno o kvaliteti upravljačkih centara. Najčešće korišteni kvantitativni pokazatelji kvalitete upravljačkih centara su: pouzdanost, raspoloživost, sigurnost i sustav u otkazu. Stoga je u radu kreiran blok dijagram pouzdanosti i model pouzdanosti/raspoloživosti (Markovljev model) te je izvršena detaljna analiza i proračun kvantitativnih pokazatelja kritičnih komponenti (serveri) upravljačkog centra. Kvalitetno funkcioniranje upravljačkih centara omogućit će prikupljanje, obradu, spremanje i distribuiranje pravovremenih, sigurnih i pouzdanih podataka i informacija službi nadzora i upravljanja pomorskim prometom.
