Fuzzy MADM approach for selecting the best wetlands environment plan

This paper presents a fuzzy multi-attribute analysis approach for selecting the best plan alternatives in wetlands environment. The Fuzzy Analytic Hierarchy Process (FAHP) method is used to determine the preference weightings of criteria for decision makers. A questionnaire was used to find out from three related groups comprising 15 experts, including five from the university of expert scholars (include Water Resources Engineering and Conservation, Landscape and Recreation, Urban Planning, Environment Engineering, Architectural Engineering), five from the government departments, and five from industry. The subjectivity and vagueness is dealt with the criteria and alternatives for selection process by using fuzzy numbers with linguistic terms. Incorporated the decision makers´ attitude towards preference, overall performance value of each alternative can be obtained based on the concept of Fuzzy Multiple Attribute Decision Making (FMADM). A case study consisting of five alternatives, solicited from a wetland environment plan works in Taiwan, is illustrated to demonstrate the effectiveness and usefulness of the proposed approach.
