United Nations formulated Sustainable Development Goals (SDG) in 2015, which are the collection of a set of objectives to provide a world to people with peace and prosperity now and in the future. 17 goals are identified as achievable targets in 2030 and they contain elimination of poverty, hunger, inequalities and improvement of health, education, environment, security and economic conditions around the world. One of SDGs is defined as clean water and sanitation and known as SDG6. Clean water and sanitation is essential for health and well-being of people and evaluation of countries considering several indicators of SDG6 simultaneously should be done. Especially in MENA countries, clean water and sanitation is a popular topic and the main aim of this study is to develop a multi-criteria evaluation model for these countries in views of SDG6 indicators. To do so, a hybrid approach based on Interval Valued Intuitionistic Fuzzy Analytic Hierarchy Process (IVIF-AHP) and Technique of Order Preference by Similarity to Ideal Solution (TOPSIS) methods is proposed. IVIF-AHP is used to determine indicator weight values and TOPSIS is used to obtain the ranking of countries. Evaluation of MENA nations is conducted to show the viability of the suggested approach. The results of the study could be useful for sustainable management of water and sanitation systems in these countries.
