Abstract
A multicriteria approach with temporal indicators in optimizing the distribution of cargo flows in multimodal transport and technological system is presented. Based on the infrastructure indicators of the considered part of the railway landfill and the economic and geographical volumes of cargo accumulation, a mathematical model of the transport process is developed, expressed as a nonlinear integer programming problem. For various combinations of several objective functions, which are temporary indicators of the transportation process, an algorithm of optimal distribution of cargo flows for the considered loading stations and unloading stations is developed. Computational procedures for finding the Pareto optimal distribution of cargo flows are implemented in the environment of a computer mathematics system, which can be Free Ware. The distribution of grain cargo flows, which, as well known, are especially relevant from a commercial point of view for Russian exports, was chosen as a specific object for implementing the developed optimization approach.
