IMPROVEMENT APPROACH TO THE CALCULATION OF RATIONAL PARAMETERS OF THE PROCESS OF HANDLING TRAFFIC VOLUMES IN THE "YARD – FREIGHT STATION – DISTRICT PARKS PORT"

Abstract

Purpose . The aim of the article is to improve the processing of traffic volumes in the «Marshaling yard - freight station - the port railway yard» by improving the scientific approach to the calculation of rational parameters. Methods. To determine the rational parameters of the process handling traffic volumes in the system identified measures to increase the efficiency of processing technologies traffic volumes, which will be held in the system. To obtain the results of their impletion created a mathematical model that shows the value of the effectiveness of these measures. The optimality criterion is adopted by at least a share of operating costs in the processing of traffic volumes in the system. Control parameters are the volume of traffic volumes with priority and conventional treatment, the number of groups of cars, which are served in the port area of the park, and the number of cars in each such filing. Restrictions on the control parameters define the area of feasible solutions in the form of a system of linear inequalities. Results. The technology of the redistribution of traffic volumes between sorting and port freight station on the basis of priority of service cars destination seaports. Formed mathematical model to determine its rational parameters. Scientific novelty. First proposed a scientific approach to the calculation of rational parameters of the processing of traffic volumes in the «Marshaling yard - freight station - the port railway yard» based on the minimization of the proportion of operating costs for processing these streams through the use of their priority service since the end of the dissolution of the formulations to the yard the moment the group of cars in the port railway yard. The practical significance. Redistribution Job processing traffic volumes appointment seaports reduces the length of time the cars on the portside freight station by eliminating the need to recycling, reduce unproductive time waiting for technological operations, to reduce the duration of the process steps in the loading station.
