A new hybrid preference framework of the Graph Model for Conflict Resolution (GMCR) is proposed to facilitate modeling and analysis of conflicts involving two decision makers (DMs) with fuzzy levels of preference. The new preference structure, a hybrid of models of three-level strength of preference and fuzzy preference, provides a more flexible technique to express DMs' relative preferences among...
The organizational environment is defined by a complex and dynamic interaction of elements that act together to achieve goals. Organizational modeling helps stakeholders to better understand this complexity and analyze details in order to help the identification of changes that are necessary to keep the organization aligned with its strategic goals. However, it is still hard to map the many organizational...
Reputation-based methods have been widely proposed and practised to foster online trust relationships. Previous works introduced the concept of reputation utility that bridges reputation and trust to reveal the reciprocal transformation mechanism between them. In this paper, an improved model, concerning the popularity of online entities, is constructed. Based on the model, further exploration on...
Over the last decades there has been a growing interest in modeling human performance and analyzing human activity and human operator behavior to improve system design. A variety of tools and approaches which are based on task analysis methods and tools have been proposed. As technology advances and tasks become more demanding, human work changes increasing the need to create new methodologies and...
In this study, we conduct agent-based simulation experiments of network formation focusing on a mathematical model proposed by Berninghaus et al. (2007) such that a periphery sponsored star network is the strict Nash equilibrium. Hayashida et al. (2011) conducted the simulation experiment using NN(Neural Network) and GA(Genetic Algorithm) model to analyze behavior of human subject in the experiment...
In this paper we describe the tool we have developed to visualise experimental data on top of the multi-agent simulation platform Presage2 and how we have used it with our Social Capital Framework. The visualisation demonstrates how social capital can be used to self-organise solutions to collective actions problems.
This article presents a tool developed to follow up and to evaluate the student learning using Fuzzy model. This tool enable the coordination of Classroom mediated by technology (CMT) courses at University of State of Amazonas to elect the best teaching practices that allow the increasing of student's performance. The course coordinators will have a tool to support decision-making, assisting professors...
In this paper, through by using the AHP (Analytic Hierarchy Process) method's basic theory analysis in online-teaching platform, analyzing ability of students' self-learning, and establishing the evaluation index system, according to expert criteria derived the value of influence factors. With it calculated every level index's weight by using the square root method, and implements the weight by given...
The purpose of this paper is to explore a scientific method to assess excellent students. By analyzing the factors affecting excellent students, this paper proposes a new method—feature AHP, based on the established AHP model. The results of this method are in agreement with our evaluation principle for excellent students in most schools. As a conclusion, this method has the advantage of giving a...
The complexity and uncertainty of prediction on power supply and demand are analyzed in this paper, and studies the meta-synthesis method of man-computer integration from qualitative analysis to quantitative analysis. The meta-synthetic seminar hall system for power supply and demand research is designed and implemented. The system integrates power economy information, knowledge and experience of...
Consensus formation models are useful for obtaining harmonious consensus in a group when all group members pursue their individual preferences. In the process of consensus formation, each agent accepts macro-information and adapts its preference to the overall group preference. Flexible Interpretive Structural Modeling (FISM) is a method for developing structural models of complex systems. In this...
In e-commerce environments, problems of credit risks are more serious than that of the traditional commerce due to interactions between unfamiliar peers. The application of credit evaluation system for e-commerce plays a important role in mitigating credit risks. This paper proposes an improved AHP-based multi-dimension credit evaluation model based on an analysis of the drawbacks of the current model,...
Self-adaptive systems aim at autonomously achieving their objectives in a dynamic environment, adapting their behavior to different circumstances. We claim that appropriate software engineering methodologies are needed to define and to model the information necessary for a system to perform autonomous diagnosis and decision making at runtime.In this short paper we focus on conceptual modeling for...
New definitions and methodology are proposed in this paper to predict the most likely outcomes of multilateral negotiations. The negotiation problems modeled and analyzed here are distinctive because the set of possible agreements is discrete and specified in advance. Each decision maker has two concerns: first, achieving an alternative that is as preferable as possible; second, building support among...
This paper presents LEA a Web application for summarization exercise development. Appropriate for learners on different summarization ability levels as well as for various learning domains. The summarization environment provides edition facilities and aid tools to support learning. It assists during the summarization task and performs automatic assessment. The automatic summary grading process is...
In this paper we propose the concept of an instantiative fuzzy set which, in our opinion, constitutes a meaningful addition to the notion of a non-stationary fuzzy set. We begin with a formal definition of an instantiative fuzzy set, and follow specifying basic classes of instantiative fuzzy set operators: the union, the intersection and the complement. Furthermore, we provide formal definitions of...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
Information privacy typically concerns the confidentiality of personal identifiable information (PII) and protected health information (PHI) such as electronic medical records. Thus, the information access control mechanism for e-health services must be embedded with privacy-enhancing technologies. Role-based access control (RBAC) model has been widely investigated and applied to various applications...
