AHP-VIKOR Bridge Structural System Selection in Urban Areas Tehran: InterchangesCase Study

摘要

The election of “Structural system” is one of the most important factors in any bridge and infrastructure design. Designers perform the structural calculations for the project determines the priorities as well as design and performance criteria. Further analysis of the structural selection problem and the identif ication of the bridge desirable capabilities, triggered the consideration of analytic hierarchy process (AHP) as a possible basis for the decision making. The methodology uses the VIKOR to evaluate the alternatives according to the decision criteria and determine the solution. The methodology was developed by a group of bridge designers involved in design and management of urban infrastructure projects and demonstrated using a Steel Girder bridge in an urban area as an optimum alternative.
