Adoption of fuzzy analytical hierarchy process for assessment of urban regeneration and renewal development proposals

Abstract

Urban regeneration and renewal opens up new horizons of development by contributing to the upgrading of our surrounding communities. Regenerating urban regions has been recognised as a complex process, since it includes comprehensive principles consisting of different physical, social and technical elements. Moreover, the data provided in regeneration development projects involves uncertain and ambiguous concepts, which are often represented in qualitative measurements with the problematic nature of scales. Therefore, traditional evaluation techniques have proved unsuitable when dealing with these types of project, since they have failed to deliver precision and accuracy in assessment results. The objective of this research is to develop an assessment model using fuzzy logic to assess urban regeneration and renewal development proposals. Fuzzy is the mathematical models of verbal expression in the area of specialisation. This study illustrates a way to convert non-intuitive and precise concepts to measurable and accurate results from which to develop a model. This would allow the evaluation of urban development results to be enumerated, quantified and computerised. Urban planners could then obtain immediate feedback on the relative quality of urban development decisions. Results showed the efficiency of the developed model and the possibility of using this to reach an ideal alternative to the indicator of urban development. It proves its efficiency and proficiency in dealing with the inaccuracy of converting urban design qualitative values to numerically quantified values. In the same way, this model could be used in the evaluation of urban proposals in both academia and practice, such as architectural competitions and graduation projects.
