Application of AHP and ELECTRE III/IV Methods to Multiple Level, Multiple Criteria Evaluation of Urban Transportation Projects

In this paper the authors carry out a multiple level, multiple criteria evaluation of 18 urban transportation projects. At each level of the hierarchical decision problem different multiple criteria ranking sub-problems have been structured and solved with the application of AHP method, ELECTRE III/IV method and their combination (AHP/ELECTRE III/IV). Thus, the computational phase allowed for testing the above mentioned multiple criteria ranking methods, i. e.: AHP and ELECTRE III/IV and analyzing their suitability for performing a multiple level, multiple criteria evaluation of transportation projects. Due to axiomatic differences between methods alternative aggregation formulas of the generated rankings by ELECTRE III/IV and AHP methods have been proposed. A multi - aspect discussion and comparison of generated results and applied methods have been presented.
