MODEL OF SOLUTION OF OPTIMIZATION PROBLEMS

The article refers to main outlines of mathematical model of rail transport. The authors substantiate the necessity to use dynamic programming method to optimize the parameters of the rail sector state. They argue the utility to use rail car department as a sort of department that is a «vehicle» of a key model idea. The authors suggest requirements concerning objective function, its formulae, and a tool to transform it into additive function via solving auxiliary optimization problem. They prove the necessity to realize a new paradigm of car designing model, which is mandatory for effective use of achieved optimum parameters of rail sector state. The management system for rail sector, as it is considered by the authors, is deemed to be multilevel and hierarchic, allowing there-by to analyze problems relevant to local conditions and objectives and according new possibilities to assess transit capacity of Russia and to create globally railway nets with scientifically bases management system. The implementation of such project might permit to achieve advantages for railway transportation, notably taking into account the maintenance of ecological balance and reduction of carriage costs, to gain part of market of truck, air and sea haulage.
