Fedorov A. Models, methods and information technology of the support of control processes of cargo operations of container ships

The research is devoted to the issues of the efficiency and safety improvement of cargo operations on container ships during multiport transportation by improving the automated control systems of such operations. Object of research is the process of control of the cargo operations of a container ship. The purpose of the thesis is to improve the safety and efficiency of container cargo operations by developing new models, methods and information procedures for control of the cargo operations. Research methods: to achieve the goal of the research formal-logical models and methods of evolutionary modeling are used to build a master plan of a container ship, methods of dynamic programming and search with constraints are used to form a cargo plan of a container ship, analytical models are used to calculate the stability of the ship during loading. The technological features of container transportation by sea are considered in the thesis. It is determined that the key aspect of their efficiency and safety improvement is the creation of automated systems and DSS for the control of cargo operations of container ships. A comparative analysis of existing mathematical models and methods of formation of cargo plans of container ships is carried out; their basic advantages and lacks are defined. Models and information technology for the control of cargo operations of container ships during multiport transportation based on the combination of logical rules of loading/unloading and heuristics problem-solving methods are developed. A two-phase four-stage method of formation of a cargo plan of a container ship based on the combined application of formal-logical and heuristic models was developed. The application of the proposed approach to the formation of the optimal cargo plan of the vessel provides a solution for a reasonable period of time for practical usage. Methods of placement of containers on a container ship considering its construction features and technological limitations for cargo operations were further developed. A prototype of DSS for control of container ship cargo operations for multiport transportation based on the developed models, methods and algorithms was created. It allows increasing the level of security of container cargo operations, the efficiency of sea container transportation, and reducing human impact on ship cargo operations control processes. Scope is processes in educational and scientific institutions, in training centers for the training of crew members, on container ships.
