Choosing the optimal solution to increase train speeds using mathematical modeling

Abstract

   It is possible to increase the speed of trains on existing railway lines by carrying out reconstruction measures. Such measures may include: electrification, construction of an additional track, modernization of communication facilities, extension of the receiving and sending lines, and the use of inserts on the stage, the introduction of new rolling stock.
   Reconstructive measures to increase the speed of movement on the railway should be designed in such a way that the safety and continuity of train traffic are ensured, the time of passengers on the road is reduced, while ensuring the required transport sizes and the lowest construction and operating costs. To choose the optimal solution to the tasks of designing the reconstruction of the railway is carried out on the basis of mathematical modeling.
   The need to make decisions that do not fully take into account the conditions that determine them, as well as their subsequent impact, is found in all areas of technology, in particular when introducing high-speed traffic on railways. The article proposes a method for solving this problem using a decision support system. It is a computer system designed to analyze and select decisions based on objective data and subjective judgments of the decision maker.
   The essence of the program is to enter a list of possible solutions and specify criteria for comparing alternatives. Next, for each criterion, its type and weight are specified (the evaluation of the importance of the criterion). The requirements for all the proposed options are introduced and a generalized evaluation of each alternative is calculated, taking into account all the criteria and rules. The last step will be to choose the best option for the recons
