A fuzzy multi-criteria decision analysis approach for the management of petroleum-contaminated sites

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.
