Multi-criteria Assessment of Sustainability for Energy Systems Under Uncertainty: Grey-Based Approach

Energy supply and related systems have gained increasing importance in recent years. Energy supply is not only related to the energy sources but also related to production, distribution, storage, sustainability, etc. As the concept of sustainability, it also includes the other important components of energy systems. Because sustainability is valid for everything and one of the most important topics in today’s world. Therefore, sustainability of energy systems should be considered in a holistic manner. Thus, the sustainability of energy systems can be evaluated more accurately and broadly. In this study, a grey-based multi-criteria approach is proposed to assess the sustainability of energy systems under uncertainty. The proposed approach contains two main methods; the grey analytic hierarchy process and the grey MOORA method. In the first part, grey analytic hierarchy process is used to combine the subjective evaluations of the experts and generate the grey decision matrix. Then, in the second part, grey MOORA method is applied to the grey decision matrix for the assessment of sustainability for energy systems under uncertainty. An example is also given for displaying the applicability of the presented approach. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
