Determining the priority criteria and ranking of provincial bridge maintenance in West Sumatra using a combination of the Fuzzy Analytical Hierarchy Process and VIKOR-Modification methods

Abstract

There are many bridges that need to be maintained in a provincial road network, with limited funds for bridge maintenance, many bridge criteria (average daily traffic, economic benefits, fund budget, technical conditions, bridge hierarchy, spatial planning, flood potential, type of damage, erosion potential, age and surface concrete, etc.), and various levels of conditions, are a number of criteria that are taken into account in the decision making by the government as an institution responsible for the functioning of roads and bridges. The selection of bridge maintenance priorities in West Sumatra Province was decided through a coordination meeting between agencies, and sometimes relatively without going through sufficient technical analysis. This research initiated, the selected criteria to be taken into consideration, the order of the important criteria in the selected network segment. This study involved a number of road and bridge maintenance experts at the Ministry of Public Works, Road and Bridge Research and Development Institutions, as well as the Department of Public Works and Spatial Planning of West Sumatra Province. A combination of Fuzzy Analytic Hierarchy Process (to determine weighted criteria) and VIKOR-Modification methods (to determine the order of choice of bridges to be handled) are selected. There are eight criteria that can be used in determining the priority of bridge maintenance, and the priority sequence of the most important are: bridge technical conditions, aging of the bridge, average daily traffic, economic benefits, road function, budget, disaster risk (Flood, Landslides, Tsunamis) and Spatial Plans.

A Systematic Review of Marine Risk Assessment: The Fuzzy Analytic Hierarchy Process (FAHP)

“…The results that were produced are simultaneously directed toward avoiding accepting the perspectives of numerous decision makers who take the time to evaluate and have a variety of doubts about the situation [39], [40]. FHAP can, in an indirect manner, save time, and the procedure itself is more methodical than more conventional methods.…”

Integrative Evolutionary-Based Method for Modeling and Optimizing Budget Assignment of Bridge Maintenance Priorities

“…They concluded that the developed model could visualize the prioritization of bridges for maintenance, which improves the decision-making process in the departments of transportation. Yossyafra et al (2019) presented a hybrid multi-criteria decision making model for maintenance prioritization of bridges in West Sumatra Province. They utilized fuzzy analytical hierarchy process to compute the weights of attributes, which were technical condition, age, average daily traffic, economic benefits, road function, budget fund, disaster impact and spatial conditions.…”
