Multi-criteria analysis of urban policy for sustainable development decision-making: A case study for Warsaw city, Poland.

In order to track how cities develop and grow, multidimensional systems of urban development indicators taking into account the balance between economic, social, and environmental aspects are the best solution found so far. However, there is no unique measurement system that would be widely accepted and applied within various urban areas to verify whether a given city is developing in a sustainable way. The aim of this paper is to apply the TOPSIS algorithm on the basis of selected urban indicators, in order to evaluate the progress of a single city towards the concept of sustainable development observed over a longer period of time. A capital city of Poland, Warsaw, faces several challenges associated with development policy evaluation, thus confirming the need for this research. We meticulously selected 48 indicators from the economic, social and environmental areas as an input for TOPSIS algorithm, which allowed us to calculate a new proposed aggregated index for evaluating urban policy on the example of Warsaw. Research has shown usefulness of applied TOPSIS algorithm in assessing the long-run development of an urban area towards the concept of a sustainable city. The results of our analysis indicated that over a period of ten years, during 2008-2017, the urban policy decision-making has been balancing the socio-economic and environmental aspects and the city of Warsaw has been developed in a sustainable manner.
