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....
It is normally that the enterprises have partial demand information about the single-period products due to the short sales period and quickly demand changes. Under price-dependent demand, the demand uncertainty will be larger. In this paper, the maximum entropy formulism is employed to establish a model to find the most possible distribution. Then it discusses the independent inventory decision and...
The thesis introduces entropy and dissipative structure theory of thermodynamics into the evolved study of compensation administration system. According to the compensation administration system's dissipative characteristics, entropy model is constructed on the basis of evolving compensation administration system. Through the quantization in terms of entropy, the thesis investigates the evolution...
Network security has become a major concern in recent years. In this research, we present an entropy-based network traffic profiling scheme for detecting security attacks. The proposed scheme consists of two stages. The purpose of the first stage is to systematically construct the probability distribution of relative uncertainty for normal network traffic behavior. In the second stage, we use the...
We consider a secure lossless source coding problem with a rate-limited helper. In particular, Alice observes an i.i.d. source Xn and wishes to transmit this source loss-lessly to Bob at a rate Rx. A helper, say Helen, observes a correlated source Yn and transmits at a rate Ry to Bob. A passive eavesdropper can observe the coded output of Alice. The equivocation ?? is measured by the conditional entropy...
Information theoretical concepts can be used as most valuable tools for evaluating clinical chemical tests. They offer several advantages over the conventional test evaluation by Bayesian concepts. Although long known, information theory has failed to gain widespread acceptance among clinical chemists, probably due to the rather laborious computation of the necessary quantities. To resolve this technical...
This paper outlines several strands in the historical development of structural optimization techniques. The first is indirect via simple optimality conditions such as uniform density of stress or strain for achieving a technical objective like minimum weight, maximum stiffness or minimum strain energy. In the case of prestressed structures, zero net displacement of the concrete in flexure at service...
