Abstract
This paper presents an effective Fuzzy Multi-Criteria Decision Analysis (FMCDA) approach for contaminated site management. The development was based on: selecting eight criteria for remedial alternative evaluation and determining the weight of criteria importance under uncertainty; addressing various uncertainty issues in remedial alternative assessment process using a fuzzy-set approach based on the questionnaire survey results; evaluating and ranking remedial alternatives by establishing a fuzzy evaluation matrix of remediation alternatives through comprehensively considering different stakeholder opinions and uncertainties within a general decision analysis framework. A case study on the remedial alternative selection for a contaminated site in western Canada is conducted to illustrate the efficiency and applicability of the developed approach.
