Abstract

Multi-attribute analysis (MAA) is a popular tool in many economical, managerial, and constructional problems. This document provides a review of international and national practices in investment decision support tools in bridges and road quality management. Cost benefit analysis (CBA) and MAA are principal methodologies in supporting decisionmaking in bridges and road quality management. The complexity of the applications shows significant differences in international practices. There are ongoing discussions among practitioners and researchers, regarding which one is more appropriate in supporting decisionmaking. It is suggested that more than one approach should be regarded as complementary instead of competitive means. MAA may be particularly helpful in early stages of project development and strategic planning. CBA is used most widely for project prioritization and selecting the final project from a set of alternatives. These methodologies are applicable to the problems with large numbers of scenarios and attributes. The research has concluded that multi-attribute decisionmaking methods are very useful for bridge and road construction.
