Integrated FUZZY-AHP-TOPSIS Model for Offshore Wind Farm Site Evaluation Selection: Ninh Thuan Province case

In the aftermath of the COVID-19 pandemic, the paramount task lies in revitalizing and propelling the economy, political landscape, and education sector while embracing the global shift toward adopting clean and renewable energy sources. The pressing issue of climate change, with its detrimental consequences on the environment and human well-being, has propelled a vigorous transition towards sustainable renewable energy sources, such as offshore wind power. This study focuses on selecting criteria to optimize the location of offshore wind farms in Ninh Thuan province, representing a comprehensive and specialized effort within the Vietnamese research context.The integrated method of Multi-Criteria Decision Making (MCDM), specifically the fusion of Fuzzy-AHP-TOPSIS, is employed to evaluate and select ideal sites for offshore wind farms. Utilizing the hierarchical FUZZY-AHP analysis method, the weightings of four evaluation criteria are determined, including technical, economic, social, and environmental. Subsequently, the TOPSIS object ranking model is applied to yield optimal results based on the initial ranking order of the criteria.By developing this combined method, the study offers stringent methodological support for site selection to achieve benefits in coastal zone management. Furthermore, it makes significant contributions to the field of wind energy, aiding decision-making processes in selecting and optimizing offshore wind farms, particularly in Ninh Thuan. The assessment criteria and this methodology could be extended to other coastal municipalities to advance Integrated Coastal Management (ICM) towards sustainability objectives.
