Selection of the Method for Rehabilitation of Historic Bridges—A Decision Support Concept for the Planning of Rehabilitation Projects

Abstract

This article presents a decision support concept for management of rehabilitation projects. The focus of the research is on the application of multicriteria methods of decision-making in planning a historic bridge rehabilitation project. The problem addressed in this research is a major one from many different perspectives, such as civil engineering, economics, etc., which indicates a need for the evaluation of different rehabilitation methods using several different criteria. Therefore, a decision support concept for a historic bridge rehabilitation method based on the PROMETHEE method has been designed. Three groups of stakeholders have been included (civil engineering experts, economic experts, and government experts) to define appropriate criteria, their weights, and preference functions. For determination of criteria weights, the AHP method has been used. The model has been tested on the problem of choosing the rehabilitation method for the Pavića Bridge in Croatia.
