Comparative Assessment of Several Multi-Criteria Decision Analysis Tools for Management of Contaminated Sediments

摘要: Over the past several decades, environmental decision-making strategies have evolved into increasingly more sophisticated, information-intensive, and complexapproaches including expert judgment, cost-benefit analysis, toxicological risk assessment, comparative a number of methods forincorporating public stakeholder values. This evolution has led to an improved array aids, development Multi-CriteriaDecision Analysis (MCDA) tools that offer scientifically sound decision analytical framework. The existence different MCDA availability corresponding software contribute possibility practical implementation these methods. However, even though great deal work been done in justifying theoretical foundation methods, real-life applications are rare. critical attitudes schools toward alternative approaches may obstacle application MCDA. Additionally, no method is theoretically appropriate for group processes, all necessarily use significant simplifications assumptions rank policy alternatives. Nevertheless, this paper illustrates three two case studies involving management contaminated sediments. These based on real sediment problems experienced by US Army Corps Engineers other stakeholders New York/New Jersey Harbor Cocheco Superfund Site Hampshire. Our analysis shows points similar solutions, matter which tool applied. were constructively used determine strengths weaknesses each when solving problem.
