As the Internet services spread all over the world, many kinds and a large number of security threats are increasing. Therefore, intrusion detection systems, which can effectively detect intrusion accesses, have attracted attention. This paper describes a novel fuzzy class-association-rule mining method based on genetic network programming (GNP) for detecting network intrusions. GNP is an evolutionary...
With the help of fast and cheap information technology GPS navigators for car navigation are becoming very common. But unlike vehicle users, pedestrians form a more heterogeneous group having different levels of physical abilities with varieties of conditions, personal preferences and needs. The lack of data to support pedestrian navigation also imposes a harder challenge to design generalized navigation...
In data mining approach, the quantitative attributes should be appropriately dealt with as well as the Boolean attributes. This paper presents a fast algorithm for extracting fuzzy association rules from database. The objective of the algorithm is to improve the computational time of mining for the actual application. In this paper, we propose a basic algorithm based on the Apriori algorithm for rule...
Evolutionary algorithms are an important branch of soft computing, being able to provide approximate solutions to problems in a reasonable amount of time. The underlying principle can be realized in an almost unlimited number of ways. This paper presents four main variants of evolutionary algorithms, and a method of running them in a topology consisting of multiple populations. The resources given...
Japan is facing two problems of aging population and declining birth rate, which lead to a scenario that the elderly are at home alone and no one takes care of them most of time. Therefore, there is need of developing the elderly care supporting systems. This paper presents a system for supporting the elderly at home in medicine management, medicine taking monitoring, and medicine taking assistance...
The goal of this paper is to provide calculation formulas for the possibilistic correlation coefficient and ratio for two marginal possibility distributions of triangular form when their joint possibility distribution is defined by the product t-norm. We will also introduce an alternative definition for the possibilistic correlation coefficient and ratio when their joint possibility distribution is...
Radio Frequency Identification (RFID) is used in different applications. RFID technologies are getting considerable attention not only from academic research but also from the applications for enterprise. One of the most important applications of RFID research is the indoor position location. Many researchers have used varied technologies to perform the action of indoor position location tracking...
Lots of risks existed in the process of Emergency Logistics especially when natural disasters happened. Evaluation research on Emergency Logistics Risks (ELR) is the basis of effective early warning and responding to risks, so it's of great theoretical and practical significance to establish an early warning index system for ELR. Firstly, some foundation research about ELR was carried out, including...
At container terminals, containers are transported from the marshalling yard to the quay and vice versa by Container Trucks (CTs). This study discusses how to dispatch CTs by utilizing information about pickup and delivery locations and time in future delivery tasks based on dynamic dispatching strategy in which multiple tasks are matched with multiple CTs. In this paper, Multi-agent system (MAS)...
For features of planning and design's evaluation, and on basis of the principles of establishing evaluation index system, this paper established the comprehensive evaluation index system of residential planning and design program; In the use of analytical hierarchy process to determine weights of evaluation indexes, and based on the character of fuzzy comprehensive evaluation method that using dimensionless...
This article creates a green supply chain performance evaluation index system from the six aspects of financial indicators, information indicators, customer service indicators, the development and innovation indicators, business process indicators and environmental protection indicators. Then we describe the method of overall performance evaluation of green supply chain in detail from the index weight...
Based on full investigation and further research of DSM, this paper established comprehensive evaluation index system, adopting fuzzy mathematics and Grey Theory. It established evaluation matrix of ray fuzzy in grey statistics, defining the weight of evaluation index according to grey correlation analysis. Evaluating the effect of DSM according to maximum membership degree principle, furthermore,...
Taking talents policy of Shanghai government for example and basing on analysis of research of policy affectees, we setup index structure of three dimensions. These three dimensions are talent increase, talent centralization and talent efficiency. We measured talents policy of Shanghai from year 2001 to 2006 with Fuzzy Optimization Methodology Model. The effect of talent policy, trend characteristic...
This paper analyzed the principles of TOPSIS, used the fuzzy set to pretreat the uncertainty factors in evaluation work. Then obtain the relative closeness according to the distance between each schemes and positive ideal solutions as well as negative ideal solutions. After that, we made comprehensive evaluation. At the end of this paper, a practical example is given to illustrate the effectiveness...
In this paper, the multi-period fuzzy multi-attribute decision making is discussed, where the attribute values are considered as triangular fuzzy variables. A new approach to determine the weights of all periods is proposed. The weighted distance operator and the dynamic weighted distance operator are proposed. A distance method for multi-period fuzzy multi-attribute decision making is presented....
Motivated by EQ-algebras of V. Novák we introduce a new structure, called equality algebras. It has two connectives, a meet operation and an equivalence. As opposed to previous attempts in the literature, transitivity of the equivalence is formulated in a novel way, without reference to any conjunction. This lays down a new foundation for investigating fuzzy equivalence relations (fuzzy similarities)...
Logistics programming in natural involves dispatching commodities to distribution centres in disaster areas as soon as possible so that relief operations are accelerated. In this study, three planning models are to be integrated into a natural disaster logistics decision support system. The system readily decomposed into three problems the first one being fuzzy clustering disaster grades by historical...
Aiming at threshold uncertainty caused by fuzziness of image for image segmentation, an adaptive thresholding method for gray-level image segmentation using type-II fuzzy sets is proposed . Fuzzy index is got using type-II fuzzy sets technique, that can overcome effectively the uncertainty, histogram peaks value of an image can be find out automatically based on maximum Mahalanobis distance and minimum...
The objective evaluation of the factors influencing the performance of the innovation talents is the key to the effective investment into the innovation. Up to now, some methods as survey, experiment, case study, etc. have been used to study the performance of talents. However, most of them are qualitative approaches. So, to raise the objectivity of the study, the paper applies Fuzzy Analytic Hierarchical...
