Application of the aggregated calculation algorithm EA FAHP and fuzzy TOPSIS methods in the evaluation of railway culverts serviceability

Abstract

Managing maintenance systems of railway culverts constitutes a typical multiple criteria decision related problem which arises from the necessity to allocate limited financial resources to repair work. Culverts are ranked on the basis of evaluation of their level of structure degradation obtained with the use of a properly created set of criteria. In order to fully present the specific character of the issue under scrutiny, an innovative approach has been proposed using the aggregated calculation algorithm which combines the EA FAHP and Fuzzy TOPSIS methods. It is a decision- making and calculation model which allows to reflect the actual evaluation processes, as well as to take into account the diversity of solutions with respect to materials applied in the structures of railway culverts.
