Maintenance Model Based an Analytical Hierarchy Process

One of the main parameters of road management system is the process of prioritizing repair and maintenance alternatives and allocating resources for their implementation. In this research, after a comprehensive overview of prioritizing and allocation approaches, the Analytical Hierarchy Process (AHP) was utilized to develop a series of road repair and maintenance models. By using the AHP, it was possible to develop some of the basic data to build the parameters of models. The paired comparison tables, which were completed by groups of experts, were used in the prioritization and resource allocation models. The main sub models developed for a road section are for pavement, infrastructure and safety devices. Moreover; the infrastructure model includes, bridges, tunnels and retaining walls. Using the developed models and prioritization of alternatives and resource allocation can be preformed conveniently. The models were evaluated by comparison of modelsʹ results with the manual prioritization of four provinces by a group of experts and managers and the results were proved to he satisfactory.
