Risk and Uncertainty Analysis for Sustainable Urban Water Systems : CRC Press : 9781138000964 : 1138000965 : 01 May 2013 : A combination of future change pressures - including unprecedented growth in population, urbanization, socio-economic, and climate change - are imposing new stresses on the earth's resources and society's ability to maintain or improve infrastructure systems and environmental quality. While planning for sustainability, we need to make decisions considering those future change pressures, which are often uncertain and generate various risks in systems. These decisions determine the long-term sustainability of a system. The main outcomes of this research are a novel framework for risk and uncertainty analysis, a hybrid approach of uncertainty analysis, and fuzzy set theory based multi-criteria analysis method for decision-making. The developed framework can be applied in any other system without much modification. The algorithms for a hybrid approach to uncertainly
