Information support and quality of structural analysis of vessel modernization technology

Abstract

Abstract Modernization is an important direction to maintain and increase the efficiency of aging water transport. Vessels of various types and purposes are modernizing due to objective necessity. The actuality of this problem is connected not only with the slow process of renewal of the sea and river fleet, but also with the rapid moral aging of ships, which overtakes their physical aging. Modernization of an existing vessel is often more cost-effective for the shipowner than building or purchasing a new one. For the successful development of this direction it is necessary to have methodological and informational support which allows to determine the best modernization option based on available resources and to evaluate the quality of the work. The article describes an approach to structural analysis and quality assessment of modernization technology using informational support for functional and simulation modeling. Structural analysis of complex processes of modernization of the vessel is implemented in the form of context diagrams of these processes, which are decomposed considering the expert opinion. The proposed method of integration of functional and simulation models allows to allocate optimally all available resources and to assess the efficiency and quality of modernization work.
