Applications of Multi Criteria Decision Techniques and Nature based algorithm to identify the Coastal Vulnerability Index based on Performance, Uncertainty and Reliability of Coastal Surrounding Systems

Abstract The Coastal management systems are mainly constitute different subcomponents. The performance of the Coastal surrounding system depends on the performance of these subcomponents. But as pet the previous related studies no attempt was made in identification of the optimal ratio of subcomponent contributions to ensure maximum productivity. Again, there is a lack of scientific endeavors in relation to the determination of the priority of the components in ensuing the coastal vulnerability in coastal management system. The present study will try to identify the priority and optimal ration of contribution required from the components of a Coastal Vulnerability of Coastal Surrounding system. In this regard the advantages of Multi Criteria Decision Making and nature-based algorithms were used and once identified the outcome was validated by a physical model. According to the results of Potential Hydraulic Energy from Wave (PE) and Distance of sea from Coast of a coastal management system most effective for total output. The benefit of adopting this procedure is it approximate the solution not only based on technical aspect but also considering the economic aspect. The results were validated in physical model and concluded that the results has yielded feasible value and the procedure can maximize the performance and minimize the cost requirement to produce a design ensuing maximum productivity. This study also depicts the capacity of Failure Mode Effect Analysis based Multi Criteria Decision Making techniques for the first time which may increase the objectivity and analyticity of an investigation.
