A DEMATEL method with single valued neutrosophic set (SVNS) in identifying the key contribution factors of Setiu Wetland’s coastal erosion

This study intends to employ the decision-making trial and evaluation laboratory (DEMATEL) method to identify the influential factors contributed towards coastal erosion. This investigation specifically studies the coastal erosion in Setiu Wetlands coastal areas which located in Terengganu, Malaysia. The single valued neutrosophic set (SVNS) is used into the DEMATEL instead of crisp numbers. Twelve factors of coastal erosion with three dimensions were identified from literature review and consultation with group of experts. By considering the interrelationships among factors, DEMATEL is applied to acquire the importance and cause-effect relationships among the influential factors of coastal erosion. Obtained result reveals that coastal development gives a significant influence in contributing coastal erosion. The result from this study offers an insight for stakeholders to understand cause-effect relationships among coastal erosion factors in which can provide a precautious short or long term strategies.
