An integrated approach for evaluation of best Oil spill cleaning methods by analytical hierarchy process and multi-objective optimization by ratio analysis

Abstract

Oil spills are considered as form of pollution that happen in marine eco system which releases liquid petroleum hydrocarbon into sea water. Oil floats in water as separate particles. Because oil spills are highly toxic, they can damage the biotic and abiotic components of the environment in which they occur. In the last few years, there have been many large and small spills in the ocean. Therefore, it is necessary to develop some effective ways to clean up oil spills. There are many cleaning options according to the type and amount of spilled liquid, environment, and weather conditions. More importantly, cleaning should be faster, more efficient, and more effective when restoring the site to its original state. There are many options, contradictions, and decisions to choose the right cleaning method. The purpose of this article is to develop an integrated model for selecting oil spill cleaning methods, including the Analytic Hierarchy Process (AHP) and Multi Objective Ratio Analysis Optimization (MOORA).  When using AHP to compute criteria weights, the MOORA technique is used for evaluation and selection of the best cleaning method. The proposed model seems to be the best one to evaluate and select choices.
