The analytic hierarchy process (AHP) approach for assessment of urban renewal proposals

The problem of urban decay in Hong Kong is getting worse recently; therefore, the importance of urban renewal in improving the physical environment conditions and the living standards of the citizens is widely recognized in the territory. However, it is not an easy task for the Hong Kong Government to prepare welcome urban renewal proposals because the citizens, professionals and other concerned parties have their own expectations which are difficult to be addressed all at the same time. Although it is impossible to satisfy all stakeholders concerning urban renewal, it is preferable to have proposals conforming to the interests of the majority and beneficial to the present and future generations. This paper adopts the analytic hierarchy process (AHP) to work out the most sustainable design proposal for an area undergoing urban renewal. AHP is a robust multi-criteria decision making (MCDM) method for solving social, governmental and corporate decision problems. Since there is a lack of published papers demonstrating a systematic and effective way for urban renewal proposal assessment, this paper attempts to fill this gap with the help of AHP.
