This study aims to identify the influencing factors of the effectiveness in energy investment. For this purpose, 8 different countries with continental shelf in the Eastern Mediterranean region (EMR) are considered. Firstly, 9 different criteria are defined based on the literature review. The significance levels of these factors are determined by considering hesitant interval-valued intuitionistic fuzzy (IVIF) DEMATEL based on 2-tuple linguistic values (2TLV). Therefore, the motivation of this study is to figure out the weights of the criteria for the energy investment projects. Also, the main contributions to the literature are to propose a set of criteria for defining the indicators of the efficiency and to construct a novel decision-making model based on IVIF technique in these projects. The main justifications of this hybrid method can be given as the importance of the distribution, political stability, and technological capacity for the effectiveness in energy investment. Furthermore, hesitant TOPSIS method is used to evaluate these 8 countries regarding the effectiveness in energy investments. It is concluded that Israel and Turkey are the most successful countries in this framework. It is recommended that these countries should have an effective pipeline to transfer the reserves to other countries. Also, these countries in this region should pay attention to political stability. Moreover, countries with energy reserves in the EMR should make the necessary investments to improve their technological infrastructure. Hence, seismic exploration and drilling vessels should be obtained by these countries so that the energy reserves can be located and obtained effectively.

基于IVIF逻辑的混合决策模型对东地中海地区大陆架国家能源投资的多维展望

本研究旨在确定能源投资有效性的影响因素。为此，考虑了东地中海地区 (EMR) 的 8 个拥有大陆架的不同国家。首先，根据文献综述定义了9个不同的标准。这些因素的显着性水平是通过考虑基于二元语言值 (2TLV) 的犹豫区间值直觉模糊 (IVIF) DEMATEL 来确定的。因此，本研究的目的是确定能源投资项目标准的权重。此外，对文献的主要贡献是提出了一套定义效率指标的标准，并在这些项目中构建了基于 IVIF 技术的新型决策模型。这种混合方法的主要理由是分配、政治稳定和技术能力对于能源投资有效性的重要性。此外，还采用犹豫TOPSIS法对这8个国家的能源投资有效性进行了评估。结论是，以色列和土耳其是该框架中最成功的国家。建议这些国家建立有效的渠道将储备转移到其他国家。此外，本地区国家应注重政治稳定。此外，EMR中拥有能源储备的国家应进行必要的投资，以改善其技术基础设施。因此，这些国家应该拥有地震勘探和钻井船，以便有效地定位和获取能源储备。
