AN EXAMPLE OF COLLECTIVE DECISION MAKING ON THE CHOICE OF AN OPTION FOR RECONSTRUCTION OF A RAILWAY SECTION

Abstract

Due to the important role of railway transport in the country's freight turnover and the constantly increasing load on the track measures are being taken to reconstruct and develop railway lines. When reconstructing railway sections, various design solutions are possible: reconstruction of the railway line plan to increase the speed of freight and passenger trains, replacement of the superstructure of the track, elimination of sore spots in the roadbed, reconstruction of artificial structures, construction of additional main tracks and double-track inserts and others. The selection of measures for the reconstruction of a railway line is a multi-criteria task. To evaluate options for design solutions, various indicators are used - private efficiency criteria. Some criteria should be minimized, others maximized. To structure the selection process and take into account various factors, it is advisable to use methods from decision theory. Determining the best option in the field of railway design (and not only) is inextricably linked with collegial choice. Group decision-making differs from individual decision-making, since the final result is influenced by the preferences of the members of the expert group, whose opinions may be different. Of course, the group can immediately reach consensus on the best option. However, this article considers the case where the experts' preferences diverge. The paper provides an example of collective decision-making on the choice of reconstruction option for a section of a railway using the linear convolution method. The final result (accepted by the group) is compared with the result obtained with an individual decision (based on the ideal point method).
