Decision-making on choosing the type of strengthening of drains and upholstery ducts based on the ideal point method
Modern materials and technologies for strengthening drainage and upland ditches, their advantages and disadvantages are considered. When choosing the type of reinforcement, the railway design engineer must compare the options for the types of reinforcement of ditches in terms of various criteria: reducing labour and resource intensity, duration of construction work, increasing durability, improving environmental friendliness, the need for special equipment, and others. An ideal point method is proposed for solving a multicriteria deterministic problem of choosing the type of ditch reinforcement. A prototype program of the decision support system for choosing the type of reinforcement using the ideal point method has been developed. The program contains four areas: the source data area; the calculation area; the guide to the types of ditch reinforcement, which separately identifies innovative types of ditch reinforcement; the area of calculation results and recommendations. With the help of the program, the test problem of choosing the type of reinforcement is solved. Of the three alternatives, a concrete roadbed is recommended-an innovative strengthening of the ditch.
