A Fuzzy Decision Making Model for Assessing Quality of Life: A Case of a Coastal Wetlands Community

摘要

This study highlights a fuzzy decision making method for assessing Quality Of Life (QOL) of a wetlands community. The assessment of QOL is a complex problem since many uncertain criteria are available and many sub-criteria are involved in the decision-making process. To deal with this challenge, the fuzzy Analytic Network Process (fuzzy ANP) is applied to proposed total weights of ten sub-criteria of QOL for a coastal community of Setiu Wetlands Terengganu. A major advantage of the fuzzy ANP is that it incorporates interdependent relationships between criteria and sub-criteria. Five experts that familiar with the QOL of coastal community were invited to provide linguistic evaluation based on the sub-criteria. Three experts suggest that the total QOL of the community is >0.5 out of one. The results also unveiled that the sub-criteria, namely politic, health care, public safety, and power and water provision are the main contributors to the QOL. The main contribution of this paper is the introduction of a fuzzy multi-criteria decision approach for assessing QOL specifically for the wetlands community.
