The ongoing industrialization and modernization period has increased the demand for energy in Viet Nam. This has led to over-exploitation and exhausts fossil fuel sources. Nowadays, Viet Nam&rsquo ; s energy mix is primarily based on thermal and hydro power. The Vietnamese government is trying to increase the proportion of renewable energy. The plan will raise the total solar power capacity from nearly 0 to 12,000 MW, equivalent to about 12 nuclear reactors, by 2030. Therefore, the construction of solar power plants is needed in Viet Nam. In this study, the authors present a multi-criteria decision making (MCDM) model by combining three methodologies, including fuzzy analytical hierarchy process (FAHP), data envelopment analysis (DEA), and the technique for order of preference by similarity to ideal solution (TOPSIS) to find the best location for building a solar power plant based on both quantitative and qualitative criteria. Initially, the potential locations from 46 sites in Viet Nam were selected by several DEA models. Then, AHP with fuzzy logic is employed to determine the weight of the factors. The TOPSIS approach is then applied to rank the locations in the final step. The results show that Binh Thuan is the optimal location to build a solar power plant because it has the highest ranking score in the final phase of this study. The contribution of this study is the proposal of a MCDM model for solar plant location selection in Viet Nam under fuzzy environment conditions. This paper also is part of the evolution of a new approach that is flexible and practical for decision makers. Furthermore, this research provides useful guidelines for solar power plant location selection in many countries as well as a guideline for location selection of other industries.

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

The period of industrialization and modernization has increased energy demands around the world. As with other countries, the Taiwanese government is trying to increase the proportion of renewable energy, especially solar energy resources. Thus, there are many solar power plants built in Taiwan. One of the most important components of a solar power plant is the solar panel. The solar panel supplier selection process is a complex and multi-faceted decision that can reduce the cost of purchasing equipment and supply this equipment on time. In this research, we propose fuzzy MCDM approach that includes fuzzy analytical hierarchy process model (FAHP) and data envelopment analysis (DEA) for evaluation and selection of solar panel supplier for a photovoltaic system design in Taiwan. The main objective of this work is to design a fuzzy MCDM approach for solar panel supplier selection based on qualitative and quantitative factors. In the first step of this research, FAHP is applied to define the priority of suppliers. The AHP combined with fuzzy logic (FAHP) can be used to rank suppliers ; however, the disadvantages of the FAHP model is that input data, expressed in linguistic terms, depends on experience of experts and the number of suppliers is practically limited, because of the number of pairwise comparison matrices. Thus, we applied several DEA models for ranking potential suppliers in the final stages. As the result, decision making unit 1 (DMU 1) is the optimal solar panel supplier for photovoltaic system design in Taiwan. The contribution of this research is a new fuzzy MCDM for supplier selection under fuzzy environment conditions. This paper also lies in the evolution of a new approach that is flexible and practical to the decision maker. It provides a useful guideline for solar panel supplier selection in many countries as well as a guideline for supplier selection in other industries.

The voting process conducted service today is still done manually so that it becomes a decision to utilize the electronic voting (e-voting) processing services. E-voting greatly reduce human control and direct their influence on this process. Provide an opportunity to resolve some of the problems that have long election but also provide a series of new concerns. Problems faced by end users in the selection is there are so many choices of software processing electronic voting services based on Information Communication Technology (ICT). Decision-making, essentially a form of election of the various alternatives of action or multi-criteria decision making (MCDM) that can be selected. In this research, decision support system (DSS) is used to select the type of service software processing electronic voting. The method used is the Multi-Criteria Decision Making (MCDM) and Analytical Hierarchy Process (AHP) using "Expert Choice 2000TM" software computer. And aims to make decisions that can help make certain parties to take the best decision in choosing the type of software processing services electronic voting. From the data processing is concluded that the first sequence is Online voting, ExpressVote second, Simply voting third, and Ballot Online fourth.

AbstractMost medium‐and long‐term decision making in industry and government can be viewed as dynamic multi‐criteria decision making (MCDM), in which the decision makers are free to alter the emphasis placed on each objective in the light of developing circumstances. In this paper the problem of time‐dependent weights in MCDM is discussed and an analysis of empirical data associated with dynamic decision making is presented.

The theory of Multi-Criteria Decision Making (MCDM) was introduced in the second half of the twentieth century and aids the decision maker to resolve problems when interacting criteria are involved and need to be evaluated. In this paper, we apply MCDM on the problem of the best drug for rheumatoid arthritis disease. Then, we solve the MCDM problem via -Sugeno measure and the Choquet integral to provide realistic values in the process of selecting the most appropriate drug. The approach confirms the proper interpretation of multi-criteria decision making in the drug ranking for rheumatoid arthritis.

ABSTRACTIn aircraft concept selection, uncertainties, resulting from economic noise variables such as fuel price, load factor, so on always exist in the decision making process. These uncertainties are often addressed using Taguchi loss functions for robustness analysis. The study presented in this paper is to utilize multi‐criteria decision making (MCDM) methods to solve an aircraft concept selection problem for a hypothetical airline when considering the robustness of the decision. Three MCDM methods were used to conduct the concept selection, including ELimination and Choice Expressing REality, simple additive weighting and technique for order preference by similarity to ideal solution. In this study, robustness is introduced as an additional decision criterion in the aircraft selection process. The impact with and without robustness consideration is compared in order to demonstrate how the proposed method makes trade‐offs between nominal performance and address uncertainty in the decision‐making process. In addition, sensitivity analysis is performed to investigate the influence of the decision criteria, especially robustness, on the final ranking of alternatives. The implementation of three MCDM methods on the aircraft selection problem also demonstrates the potential application of MCDM methods in the assessment of air transportation systems, while balancing economical, ecological, and technical constraints.
