Strategy improvements to minimize the drawbacks of geothermal investments by using spherical fuzzy modelling

Abstract

This study aims to evaluate the significant risks in geothermal energy investments. For this purpose, a model is suggested by considering the Spherical fuzzy DEMATEL technique. With the help of the literature examination, eight important risks are identified for these projects. In the following step, their weights are calculated so that more significant risk issues can be understood.Another calculation is also performed by triangular fuzzy DEMATEL to check the consistency of the analysis results. The results of both Spherical and triangular fuzzy DEMATEL techniques are similar. The most essential risk issues are the same for both methods that demonstrate the validity of the findings.The results indicate that the risk of accidents because of incorrect designmaterial use has the greatest importance since it has the highest weight. Moreover, the risks of decreased water resources and pollution of them also play a significant role in this regard. Great attention should be paid to the quality of the material to be used in geothermal energy facilities. Otherwise, there is a risk of explosion and fire in the facility. These problems threaten the lives of many people. In this process, states also have very important duties. Some standards should be determined for the quality of the material used in these facilities. In addition, the compliance of the quality of these materials with the regulations should be checked with the routine inspections. This situation will minimize the risk of accidents due to using poor-quality materials.

Assessing the Electricity Production Capacities of Emerging Markets for the Sustainable Investments

“…According to Lebbihiat et al [34], despite these issues, there are some disadvantages in the process of obtaining electricity with geothermal energy. Yüksel et al [35] identified that in this process, if the source water obtained from the underground is not returned to this source, a water problem occurs in the region. This situation causes agricultural production in the region to be adversely affected.…”

“…Finally, ranking results of the emerging economies are indicated in Table 4. The distances to the best (𝐷 𝑖 + ) and worst alternatives (𝐷 𝑖 − ) for each criterion are computed by using Equations ( 34) and (35). Similarly, the relative closeness to the ideal solutions (𝑅𝐶 𝑖 ) is computed with Equation (36).…”

Applying the Spherical fuzzy DEMATEL Approach for Identification and Prioritization of the Drone App Issues

“…In traditional DEMATEL [48], experts' hesitation is ignored. This is the first time that the spherical fuzzy version of DEMATEL [49,50] has been described in the literature for tackling this issue [51]. As a demonstration of the method's applicability, a case study is provided in the following section.…”

Yeşil Hastanelerin Gelişimi İçin Stratejik Unsurların Belirlenmesi: Enerji Bazlı Faktörlere Yönelik DEMATEL Yöntemi ile Bir Analiz

“…Son kategori ise yeşil hastanelerde verimlilik artışı olmasıdır. Böylelikle personelin hasta olması veya devamsızlık yapması önlenerek hastanede sunulan hizmet kalitesi artar ve süreklilik sağlanır [18].…”
