This paper reviews the Sybil attack in social networks, which has the ability to compromise the whole distributed network. In the Sybil attack, the malicious user claims multiple identities to compromise the whole network. Sybil attacks can be used to change the overall ranking in voting applications, bad-mouth an opinion, access resources or to break the trust mechanism behind a P2P network. I...

Selection of the best compromise irrigation plan is examined in the multi objective context. The study deals with three con ̄icting objectives: net bene®ts, agricultural production and labour employment. Three-stage procedure is adopted combining multi objective optimisation, cluster analysis and multicriterion decision-making (MCDM) methods. Two MCDM methods, namely, PROMETHEE-2 and a newly dev...

The development of artificial intelligence and the recent COVID-19 pandemic as well emergence other diseases has led to dramatic changes in overall supply chain development. choice a suitable supplier will be key ensuring sustainable company normal operation chain. However, evaluation data selection contains both qualitative quantitative simultaneously. In addition, information provided by expe...

The application of Industry 4.0 (I4.0) in the field logistics leads to emergence and development concept 4.0. Many I4.0 technologies have been applied logistics. goal this research is analyze applicability nine key centers (LC). For purpose, an integrated MEREC (MEthod based on Removal Effects Criteria)—fuzzy MARCOS (Measurement Alternatives Ranking according COmpromise Solution) model was deve...

Background. There is a weakness that the win-loss ranking model in the MLB now is calculated based on the result of a win-loss game, so we assume that a ranking system considering the opponent’s team performance is necessary. Objectives. This study aims to suggest the PageRank algorithm to complement the problem with ranking calculated with winning ratio in calculating team ranking of US MLB. ...

In text categorization, different supervised term weighting methods have been applied to improve classification performance by weighting terms with respect to different categories, for example, Information Gain, χ statistic, and Odds Ratio. From the literature there are three term ranking methods to summarize term weights of different categories for multi-class text categorization. They are Sum...

The problem of aggregating individual rankings to create an overall consensus ranking representative of the group is of longstanding interest in group decision making. The problem arises in situations where a group of k Decision Makers (DMs) are asked to rank order n alternatives. The question is how to combine the DMs’ rankings into one consensus ranking. Several different approaches have been...

The rapid growth in information technology (IT) and the implementation of IT tools has aided hospitals delivering healthcare at an unprecedented pace. However, without proper knowledge understanding software tools, establishments may find it difficult to select best hospital management system solution for their business. In this paper, a problem based on multi-criteria decision-making (MCDM) is...

Climate change, the emission of greenhouse gases, and air pollution are some most important challenging environmental issues. One main sources such problems is field transportation, which leads to gases. An efficient way deal with carrying out sustainable transportation reduce amount in an way. The evaluation vehicles can be considered a multi-criteria decision-making (MCDM) method due existenc...
