Boiko V. Improvement of operating efficiency of a steel mill freight terminal receiving bulk raw materials

Thesis on the candidate degree of Engineering Sciences by specialty 05.22.12- industrial transport. Priazovskyy State Technical University. Mariupol, 2013. The purpose of the thesis - comprehensive analysis of the approach to improvement of operating efficiency of multifunctional industrial freight terminals receiving bulk raw materials in circumstances of modifications occurred in operational performance of rail transport following transition to market economy by enhancement the technique of evaluation of processing capacity of freight terminals along with the optimization of their design and layout circuits. This thesis provides an offer as well as realization of a simulator for generation of operational and technical-economic indicators in performance of freight terminals in new circumstances when external and internal production dynamic factors of random nature effect wagon processing but through the content of the indicator "transport work", which appears for the first time with the purpose to determine loading of various technical devises available at the station so the totals are linked both with the layout-construction scheme of the terminal and with the parameters of all technical devises. On the set of research results, a methodology has been determined which allows to make an estimation of the layout-construction scheme and parameters of technical devises at the terminals receiving bulk raw materials and, on this basis, using methodology of morphological analysis and synthesis of technical solutions, to upgrade the schematic diagram of the freight terminal and improve its efficiency. Key words: dynamic factors, transport work, dynamic factor, terminal layout-construction scheme.
