Abstract

Operation of over shared resources (water, gas, oil, and mineral reserves) has been one the most significant challenges of states. "Fair" and "efficient" national resources reallocation among stakeholders and states is a complex conflict problem that faces this fundamental question: which criteria and mechanisms should be taken into account for this reallocation? In this paper, we propose a risk-based Multi Attribute Decision Making (MADM) methodology to select the most appropriate mechanism for reallocation of the reserves of the Caspian Sea with respect to several quantitative and qualitative criteria. Caspian Sea is a sea with five claimants that border it, Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. The ordered weighted averaging (OWA) method is used to evaluate the effects of risk attitude of the decision makers on the final outcome in resources reallocation. Results indicate that risk-based MADM methods are well suited tools to resolve conflicts in natural resources reallocation problems. [ABSTRACT FROM AUTHOR]

Abstract

This study proposes a promising allocation mechanism of the Caspian Sea natural resources, which are presently shared among five countries. To date, these nations have been unable to reach an allocation agreement. We apply a methodology to propose the most appropriate solution under different risk attitudes of the states. This research is different from other studies regarding the Caspian Sea negotiations in that it employs risk-based fuzzy multi attribute decision making methods for simulating the risk attitudes or optimism/pessimism degrees of the decision makers. The ordered weighted averaging (OWA) approach, which considers the optimism/pessimism degree quantitatively, is used to take into account the effects of different risk attitudes of the negotiators on the final outcome. We demonstrate how one could obtain a range of alternatives under different multi attribute and risk attitudes. The induced OWA (IOWA) method is also used to determine the relative power of these states bordering the Caspian Sea by considering several attributes, including different risk attitudes of agents. Results indicate that taking into account the risk attitude (prone, neutral, averse) of the states can affect the overall ranking of the proposed solutions. The findings from this study may facilitate negotiation regarding the most preferred allocation mechanism for the Caspian Sea. [ABSTRACT FROM AUTHOR]
