Consensus reaching process can be seen as a collaborative process in which a panel of decision makers or experts reach an agreement on developing and supporting an alternative representing their best interests. In this process some decision maker(s) may be asked to modify his/her preference(s) or opinion(s) until the final agreement within the whole can be achieved. In this paper, we propose a consensus...
With the appearance of Web 2.0 technologies, the way Internet is conceived has dramatically changed. Internet users have begun to perform a more active role in providing and sharing the information available on the Web. Thanks to mobile technologies, users can access the Internet from their smartphones at any time, independently of their location. Moreover, users gather in communities where they can...
The main aim of this paper is to identify the main causes for the delays in the Portuguese construction industry and its impact, with the purpose of increasing knowledge on the causes and impacts of delays in construction projects. The Relative Importance Index was adopted to classify the importance of the 47 causes and six impacts identified causes of delays. Results show the main causes of delay...
With the rapid growth of hierarchical data in public opinion analysis, users are in urgent need of information visualization techniques to present the data in an intuitive way in order to reveal the characteristics of the data, understand the rules behind the data, and then assist them in decision-making process. This research makes improvement in the display insufficiency of leaf nodes in the radial...
Previously we have introduced an inference-based framework for decentralized decision-making, where inferencing over the ambiguities of the self and the others is used to issue decisions. In this setting, we previously introduced the notion of N-inference V-diagnosability to characterize the existence of a disjunctive decentralized diagnosis scheme so that any fault can be detected within bounded...
Integrated test technology is the research emphasis of improving test and support capability of complex weaponry equipment. In order to solve the Analysis Hierarchical Process (AHP) method research of decision-making information system in the integrated test technology, and then to simplify the decision-making information system structure and improve the efficiency of decision-making, the paper introduces...
Grey number is the basis of grey system theory, we only know its range, and not the exact value, this number is also known as an interval grey number. Under the distribution information of interval grey numbers are already known, we use the Monte Carlo method to simulate the kernels, as well as the probability of comparing two interval grey numbers. Finally, it was applied to grey decision-making.
In this paper, first, we point out that fuzzy integers are not special cases of fuzzy numbers. Then, we define the concept of fuzzy integers, develop the methods for establishing rankings and total orderings on sets of fuzzy integers, and discuss the interrelationships between rankings and total orderings.
Based on the vector similarity theory, a new method of multi-plan optimization is proposed in this paper. The paper discusses the optimization steps of the method in detail. Finally, an example show that the effectiveness and practicality of this method by the comparison of decision results among the vector similarity method, the TOPSIS method, the angle measure sorting method and the project method.
One of the main objectives of ecology is to analyze, maintain, and enhance the bio-diversity of different ecosystems. To be able to do that, we need to gauge bio-diversity. Several semi-heuristic diversity indices have been shown to be in good accordance with the intuitive notion of bio-diversity. In this paper, we provide a theoretical justification for these empirically successful techniques. Specifically,...
This paper proposes to measure of the consensus degree of a purpose in a group decision making on a business. A group demonstrates big capability if a purpose of the group is agreed from the members. If we have the measure of the consensus degree of a purpose in a group decision making, then it contributes to activation and increase in efficiency of organizations greatly. The bosses and leaders can...
Many approaches have been proposed to quest appropriate methods in ranking fuzzy numbers. Due to the flexibility of fuzzy numbers, most of these methods are not able to calculate all kinds of ranking fuzzy numbers and some of them give inconsistent and counter intuitive results. As a result, the final ranking sometimes fails to discriminate fuzzy numbers effectively. This paper aims to propose a new...
In MCDM problems some criteria (attributes) having different importance are used to determine a best alternative from many. Thus, different weight methods exist in literature to evaluate the importance of each criteria. In this work TOPSIS, multi-criteria decision making (MCDM) method is applied using crisp data set with different techniques of weight proposed in literature. Therefore, intuitionistic...
The construction of urban bridge engineering can not only improve the traffic situation of our country, but also can produce considerable economic and social benefits. It has the characteristics of large investment, long construction period, etc. Therefore, the accuracy of the investment estimation of the urban bridge engineering has a direct impact on its construction. In order to ensure the successful...
In this paper, we take a full consideration to the location impact factors of emergency logistics center, which is technology, economy, environment and society and so on, based on sorting of the research results on the emergency logistics center location. Then, we build the hybrid multiple attribute index system of emergency logistics center location selection, and put forward the calculation method...
To solve the supplier selection problem for the large equipment enterprise with incomplete information, DEMATEL is adopted to construct the connect relationship among the evaluation index sets of each candidate supplier firstly, so we can know the mutual influence among index sets. And ANP is used to calculate the weight for each index set. Considering the incomplete information fully in the globalization...
The goal of this study is to investigate the relationship between food consumption intention and different kinds of perceived authenticity empirically. Moreover, we studied the special roles of experiential and informational familiarity play in the relationship. The result of this study indicated that different kinds of familiarity will take effect on different paths. It' important for the practitioners...
Designers of self-adaptive systems often formulate adaptive design decisions, making unrealistic or myopic assumptions about the system's requirements and environment. The decisions taken during this formulation are crucial for satisfying requirements. In environments which are characterized by uncertainty and dynamism, deviation from these assumptions is the norm and may trigger "surprises"...
A paper is concerned with a static decision (control) plant described by a relation with two kinds of unknown parameters: uncertain parameters described by certainty distributions and random parameters described by probability distributions. Different versions of the decision making in an open-loop control system are formulated and considered. A simple example illustrates the presented approach.
In a dynamic system, how to perform learning and make decisions are becoming more and more important for users. Although there are some works in social learning-related literature regarding how to construct belief for an uncertain system state, few studies have been conducted on incorporating social learning with decision making. Moreover, users may have multiple concurrent options on different objects/resources...
