AHP - Arithmetic Mean Model on Bridge Structural System Selection

Decision of selecting of a bridge structural system mostly is derived from, a few main Priorities as criteria, such as: Project cost, Construction Duration, Traffic limitation, Deck length between two piers, Passive defense capability and Maintenance costs separately. Interaction between criteria usually makes the designer not to decide in an appropriate way. AHP i.e. Analytic Hierarchy Process, is a procedure to handle a Multi Criteria Decision Making (MCDM) problem easier. By collecting a designed questionnaire from professional expertise, analyzing data would be the next step. Analyzed and averaged data and gaining its statistical elements with a formulated spreadsheet based on AHPArithmetic Mean method lead the procedure to results. In conclusion part, each bridge structural system compared with the others, and Consistency Provisions had been checked by the means of the AHP Consistency Index (C.I.), matrix Random Index (R.I.) and Consistency Ratio (C.R.) that act the main roll in verification of the results.
