This paper presents a fuzzy multiple criteria group decision-making (FMCGDM) problem with the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) based on the new concept of positive and negative ideal solution. Triangular fuzzy numbers (TFN) among decision-making process are used to evaluate the weighted different alternatives versus various. Additionally, in this paper we compared...
Decision tree, as a simple classification algorithm, is an effective tool for mining knowledge rules, and it has been successfully applied in many fields. Based on the analysis of the essential characteristics of decision tree algorithm, for the selection of the expanded attributes, we put forward leaf criterion; data utilization criterion and comprehensive effect criterion which can recognize the...
In this work we presented a forecaster software of profile of loads in power electric systems built with algorithms based on the paraconsistent annotated logic. The paraconsistent logic belongs to the family of no-classic logics and its main characteristic is the admission of the contradiction in their foundation. The forecaster of loads, which we named of "paraforecaster PAL2v", uses originated...
Bidding alliance partner selection is a key problem for bidding alliance formation, and it has the characteristics of multi-objective decision-making. In order to overcome the traditional partner evaluation's weakness, such as single goal oriented or a single process oriented, 0-1 integer programming model for selecting multi-partner in multi-projects was constructed to minimize the comprehensive...
The grey relational analysis is an important branch of grey system theory. It is the foundation of grey clustering, decision-making, and control. The aim of this paper is to further study the properties of algorithms for grey relational analysis. On the basis of analysis on the existing models for grey relational analysis and their properties, this paper first presents the novel definition of affinity...
Under a unexpected disaster, The fundamental purpose of emergency evacuation is to take a scientific and effective evacuation strategy to maximize the population of the evacuation of the affected in the shortest time, and in which, the construction of evacuation routes and the distribution of evacuation intersection flow is the key of the realization of this purpose. In this paper, aiming at the problem...
Network security situation awareness (NSSA) is a hotspot in the network security research field, based on the security situation values, decision makers can be aware of the actual security situation of their networks and then make rational decision to make their networks safer. In this paper, we build a multi-level quantization model for NSSA firstly; this model is comprised of three levels, namely,...
As an important part of requirement management, managing requirement change plays a key role in controlling project schedule and costs at early stage. Effective requirement impact analysis would give proper assessment on the effect of certain requirement changes on the whole system, and provide useful information for making trade-off decisions on future system design and implementation. In this paper...
Web service composition is a flexible way for resource sharing and application integration. However, how to guarantee quality of service composition remains a challenging problem. This paper proposes a heuristic approach to optimizing service selection for composition so that the userpsilas QoS expectation is satisfied. Optimization is enforced for constraints in both local and global level. For each...
Understanding group decision-making processes is crucial for design or operation of a complex system. Unfortunately, there are few experimental tools that might contribute to the development of a theory of group decision-making by committees of technical experts. This research aims to fills this gap by providing tools based on computational linguistics algorithms that can analyze transcripts of multi-stakeholder...
In a time of digitalization and informationization for mine enterprise, based on the complication of multiobjective ore blending planning and management, a question of fuzzy multi-objective ore blending is proposed. Then according to linguistic preference information and satisfying degree of decision maker, a fuzzy multi-objective optimization algorithm is designed. The algorithm effectively solves...
For many targets, multidimensional quantification, fuzziness of the complicated system decision characteristic information with not complete in the complex system of teaching, the logic model using fuzzy mathematics theories, constructing a kind of second class misty decision model and an algorithm is given that can carry out a teacher the teaching ability a comprehensive evaluation, solving calculate...
This paper describes a new algorithm for the evaluation of alternatives by a group of decision makers according to multiple criteria. The algorithm is motivated by the need to quickly evaluate a large number of ideas in the early stages of an innovation process, when little or no information about the ideas is available. The algorithm is based on a Markov chain model which is derived from pairwise...
In future wireless systems can ambient networks technology enable the users to utilize a multitude of networks. Frequent roaming between networks will be a key characteristic of mobile services and the terms "home" and "visited" networks will be common also at local and national level. In this paper we will investigate cooperation between operators and what benefits the end users...
A new method is presented to mine weight information from a triangular fuzzy number preference relation. Firstly, some new concepts about additive consistency are defined. Secondly, the triangular fuzzy number preference relation is transformed to some interval fuzzy preference relations by different reg-level sets. Four models are established to acquire different weight vectors. Thirdly, the final...
The purpose of image steganalysis is to find out if the hidden messages exist in images. After differencing DCT coefficients of natural-images and stego-images, their histograms present different laws. This paper regards this as the feature vector to determine if a hiding message is in the image. Through the analysis of former feature vector, the author extracts a new feature to estimate the amount...
Coil design has played an important role in design process of rectifier transformer with high-voltage, low-voltage and adjusting-voltage windings. This paper presents its optimal mathematical model, and analyzes its target functions, decision-making variables and constraints .In order to facilitate the optimization process, the constraints are disposed of with adding a penalty function or amending...
