Arkatov D. Models and information technology of railway traffic dispatching in terms of time constraints

Object of research: dispatching of railroad transport movement. Subject of research: models and information technology of data communications and dispatching motion process on railroad transport. Methods of research: theory of railroad transport dispatching, theory of data communications networks, agent based paradigm of imitation modeling, theory of distributed hierarchical systems, methods of system analysis, optimization-simulation approach, the methods of the distributed control systems theory, methods of multi-criteria optimization and decision theory, methods of simulation and probability theory, methods of the parallel computing theory, unified modeling language UML and the methodology of agent-oriented programming. Theoretical and practical results: developed a comprehensive approach to solving the problem of the railway transport scheduling, the model of parallel processing to solve the scheduling problem; developed a model for evaluating the throughput of data transmission channel, developed an information technology-based multi-agent approach. Scientific novelty consists in the development of information technology multi-agent dispatching by rail, improving multi-agent simulation model scheduling rail traffic, improving the method of railway transport dispatching traffic control, the further development of a simulation model for monitoring the navigation data channel. Elaborate information supervisory control technology automates the process of decision support manager and engineer in the operation of railway transport, and has passed the real approbation, as evidenced by acts on the use of automated motion dispatching system based on multi-agent technology in executive company "Osnovyanskaya puteyno-machinnaya stanciya" regional branch "Southern railway" of the private company "Ukrainian Railways". The results of the data link simulation and prototype software system is recommended for practical implementation in "Saytoss" company for the design of the billing system modules. Research results are used in the educational process of the Software Engineering Department and Information Technology Management NTU "KPI" in the next disciplines: "Design of Information Systems", "Modern methods of the dynamic objects control and technological processes", "Distributed software intelligent systems", "Simulation", "Design of management information systems".
