## 2 Literature Review
The analysis of decisions is a powerful approach to resolve problems involving various players, factors, and goals. MCDM issues typically consist of the following five elements: objective, selection designer's choices, options, criteria, and results [33]. The Preference Ranking Organization Method for enrichment Evaluation (PROMETHEE) and the Elimination and Choice Expressing the REality (ELECTRE) are outstanding models that are widely utilized in energy planning. They are favored because they give a wide understanding of the published information and a practical perspective that raises all questions and suspicions. On the demand side, these strategies are the best ones to use when choosing where to put energy [34; 35; 36]. [PERSON] et al. 's report examines the profitability of the six transport routes between Korea and Europe [37]. Quantitative elements (total delivery time, travel distance and total transport cost) and qualitative components (transport system, safety, and knowledge) were chosen and weighted for the analytical standards. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach was then used on the criteria to rank the routes according to their effectiveness. [PERSON] et al. discovered port intangible resources that may assist in the supply of high-quality port services and to offer a fuzzy TOPSIS method for solving the port selection issue with an emphasis on intangible resources [38]. Fuzzy TOPSIS is suitable for assisting with the decision-making process for unclear and uncertain issues, such as port selection in relation to intangible assets. In recent years, the TODIM method has been widely applied in decision making in many fields [39; 40]. An expanded TODIM technique based on bidirectional projection is presented to handle the cooperative urgent decision-making issue in the setting of uncertain triangular fuzzy sets [41]. The unique method is utilized in a research study and compared to other classical techniques. When using a projection approach to calculate choice outcomes, two projection values will inevitably be identical. The combination of the expanded TODIM approach with the bidirectional projection method may provide more logical and accurate judgment outcomes. This is an indirect technique to illustrate the uniqueness and efficacy of the suggested approach and is another benefit of collective decision-making. On the other hand, the trend to apply psycho-behavioral theories to modify MADM methods is growing [42; 43; 44]. To represent these real-world decisions including emotions rather than optimum judgments (such as value maximization), traditional theories of decision behavior have been developed. [PERSON] et al. proposed a perceived utility value-based group consistency index (which takes into account the total continuity) and a group lack of consistency indicator (which reflects the total discrepancy) for pairwise standings of options based on regret theory and a scientific hypothesis multifaceted personal taste order specified by the decision makers for an air-fighter selection method [45]. [PERSON] et al. proposed a Regret theory-based stochastic user equilibrium model of route selection by incorporating a regret aversion parameter to represent the regret level of passengers. The numerical findings collected from three example networks indicate that the regret aversion attitude does influence the route selection behavior of passengersand that the proposed model can more accurately describe the route selection behavior than current models [46]. Moreover, healthcare digitalization was processed in European Union (EU) member states. The MCDM technique can be used to assess the implementation of countries. In 2020, an evaluation for the two eHealth domains was stated. The objective is to assess the eHealth deployment in the EU Member States by synthesizing current composite indicators into an evaluation model based on multiple-criteria decision-making approaches [47].
