Multi-objective optimal operation of urban water supply systems

摘要: The world’s water resources are rapidly deteriorating due to the combined effects of global warming, climate change, population growth and fast development, posing new challenges managers. Conflicting objectives expectations various stakeholders have led increasing interests in consideration resolution multiple social, economic, environmental supply sustainability management systems, especially during extended dry periods. This study attempted develop assess potential a generic decision support framework assist evaluating alternative operating rules for multi-purpose, multireservoir urban systems. multi-objective outranking approach which facilitated incorporation stakeholder preferences making process is main focus area this research. elements illustrated on case Melbourne system, demonstrating its capabilities under single or group decision-making situations. Eight performance measures (PMs) were identified four evaluate system related sixteen pre-selected rules.
