A method of contour optimization for solving a dynamic transport problem
A dynamic transport problem is a problem of transport network development the solution of which determines the dynamics of transport flows and network state variation in a given period. Constantly increasing volumes of passenger and cargo (products) transportation require a constant transport network development as well as of renewal and updating of its elements, i.e., improvement of its technical state. In order to improve and update the transport infrastructure we need some financial, material, and other means the volume of which is limited. Therefore, of all the network extension variants we have to choose such that satisfies the needs for transport services best and can be realized with the available recourses. Thus, the problem of long-term transport network development is an optimization problem characterized by great volumes, nonlinear relations, one part of variables of which is continuous, while the other part is discrete. Since that is a nonlinear problem with a lot of extrema, its solution is a complicated mathematical problem that has no effective and universal solution methods today. This paper discusses a method for solving the problem of transport network development using the synthesis of static sections and contour optimization methods.(fragment of text)
