“…This method can not only be used to solve visualization alternatives selection problem, but it can also be used to deal with select problem of many similar issues. In the practice application, people can not only adopt the most desirable alternative, but also combine several desirable alternative.In future research, the decision model presented in this paper will be extended according to the frequency of the application in different scenarios and group decision [3,8].…”

Abstract. Multiple attribute decision making (MADM) is an efficient way to solve complex systems, and has wide application. This research develops MCDM model based on uncertain theory, used for selecting a suitable visualization alternative for tourism. First, in order to achieve desirable decision making, a new concept is proposed, which is called the best and the worst reference uncertain linguistic variable as a datum uncertain linguistic variable. At the same time, a new method for ranking uncertain linguistic variable is also presented. Second, based on the preference order relation of attributes given by the experts, a new score function is introduced to get the weight vector of attributes. Finally, the evaluation system of tourism big data visualization alternatives is constructed and the order of those alternatives is acquired by the decision method.

Weight aggregation is the key process to solve a multiple-attribute group decision-making (MAGDM) problem. This paper is trying to propose a possible approach to objectivize subjective information and to aggregate information from attribute values themselves and decision-makers' judgment. An MAGDM problem without information about decision-makers' and attributes' weight is considered. In order to define decision-makers' subjective preference, their utility function is introduced. The attributes value matrix is converted into a subjective attributes value matrix based on their subjective judgment on attribute values. By utilizing the entropy weighting technique, decision-maker's subjective weight on attributes and objective weight on attributes are determined individually based on the subjective attributes value matrix and attributes value matrix. Based on the principle of minimum cross-entropy, all decision-makers' subjective weights are integrated into a single weight vector that is closest to all decision-makers' judgment without any extra information added. Then, by applying the principle of minimum cross-entropy again, a weight aggregation method is proposed to combine the subjective and objective weight of attributes. Finally, an MAGDM example of project choosing is presented to illustrate the procedure of the proposed method.

“…According to 30,31 and; 32 it is important to develop consensus models that take into account the weights of the experts (their importance) when adding their preferences but also advising how to change their preferences. The search for consensus as expressed by 33 presents challenges and open questions to be addressed in the following areas: (1) counseling, (2) models of consensus based on trust (3) visualization and verbalization of the process, (4) the importance of the experts, (5) dynamic contexts of decision, and (6) persuasion.…”

The environmental decision problems often are divisive, even in a technical realm, decision makers with strong personalities influence outcomes. The purpose of this study is to define and quantify the factors that affect the conservation objectives of a national natural park located in Colombia, South America adding the judgments of six decision makers with different knowledge (every decision maker is also a stakeholder representative). This paper uses a hybrid multiple criteria group decision making model (MCDM), combining the social network analysis (SNA), analytic hierarchy process (AHP) and similarity measures to solve the consensus and anchoring problem among environmental decision makers. The SNA technique is used to build an influential network relation map among decision makers and to obtain their weights for applying a weighted analytic hierarchy process. Then, the final decision matrices for every decision maker are compared between them in order to identify the consensus level of the problem.Keywords: Group decision-making; stakeholder analysis; consensus; MCDM; AHP; SNA 1991 Mathematics Subject Classification: 22E46, 53C35, 57S20 IntroductionShared responsibility for the protection of nature demands common solutions to existing problems. Environmental management decisions have been the cause of many debates and deep disagreements underlying the multifaceted nature of most environmental problems. Environmental management takes place at many levels (local communities, city, state) and involves a large number of stakeholders (such as landowners, entrepreneurs, urban planners, farmers...) with conflicting interests 1 . The complexity of environmental problems requires transparent and flexible decision-making processes that integrate different areas of knowledge and values 2 . Therefore, we can affirm that environmental planning is a multi-criteria and multi-stakeholder problem by nature 3 4 . . From all of them, the AHP method proposed by 10 has been chosen because it provides an easy-to-understand framework for decision-making or evaluation problems and also it presents its strengths when working in scenarios with scarce information. AHP * For the title, try not to use more than three lines. Typeset the title in 10 pt Times Roman, bold and uppercase. 1 has also the flexibility to combine quantitative and qualitative factors, to handle different groups of actors, to combine the opinions expressed by many experts, and can help in stakeholder analysis.The purpose of stakeholder analysis is to understand their behavior, expectations, relationships and influences or resources they can bring to the decision-making process 11 . 12 suggest that the increasing use of stakeholder analysis in natural resources management reflects the recognition that stakeholders can and should influence environmental decisionmaking processes. This approach is being promoted by the EU (Directive 2003/35/EC2), and by the U.S. the Environmental Protection Agency which promote citizen participation in environmental decision-m...
