Litvinova Y. Improving the logistics management of different types of transport, warehousing and processing of cargoes in transport nodes

The aim of the study is to increase the efficiency of logistic management processes by various modes of transport, warehousing and processing of goods in transport nodes. The object of the study is the operation of the multimodal transport node. The subject of the study is the patterns of influence of parameters of input and output material flows and characteristics of production resources on the efficiency of the operation of the transport node. Research methods. For the formalization of the object of research, methods of mathematical modeling and a systematic approach are applied. Methods of simulation modeling were used to develop a model of the research object. The implementation of the program model of the research object is based on the principles of object-oriented programming. To substantiate the laws of distribution of the parameters of material flows, as well as the response functions in the series of the simulation experiment, the provisions of the theory of mathematical statistics were used. In order to determine the dependence of the criterion of the efficiency of the transport node functioning on the parameters of material flows and numerical characteristics of the production resources, methods of regression analysis are applied. Scientific novelty of the results is the proposed approach to improving the logistics management of various modes of transport, storage and cargo processing in transportation hubs due to the justification of optimal parameters of inputs and selection of the most efficient variant of the customer service process. First it is proposed criterion efficiency of the transportation hub, defined as the ratio of profit to the cost of production resources involved in the maintenance of material flow that allows counting the intra-system component of the efficiency of the transport hub apart from the traditional performance of logistics management. It is developed further: - the approach to assessing the demand for transportation hub as a set of flow parameters for service applications that previously used in the study of demand for multimodal transportation hubs; - the object-oriented approach to modelling the functioning transportation hub, allowing to assess the performance efficiency of all participants of the process, through the use of simulation models in developing specialized library classes. The practical significance of the obtained results are in developing the approaches for determination of the most effective variants of material flows service, as well as in the determination of the optimal numerical characteristics of the productive resources of the transportation hub. The practical significance of the thesis is confirmed by the results of the implementation in Dnepropetrovsk river port.
