Application of analytic hierarchy process to prioritise urban transport options - comparative analysis of group aggregation methods

摘要: This paper presents a comparative analysis of different group aggregation methods adopted in analytic hierarchy process by testing them against social choice axioms with case study Delhi transport system. The and their correctness were tested while prioritising the alternative options for energy efficient less polluting system Delhi. It was observed that among all methods, geometric mean method, most widely method process, showed poor performance failed to satisfy popular ‘Pareto optimality non-dictatorship axiom’ raising questions on its validity as method. All other namely weighted arithmetic varying weights equal individual priorities resulted concurring results member priorities. It aggregates better compared weights. Arithmetic members minimum deviation from consensus making it suitable simple aggregation.
