In this paper, the distribution of the ratio of extreme eigenvalues of a complex Wishart matrix is studied in order to calculate the exact decision threshold as a function of the desired probability of false alarm for the maximum-minimum eigenvalue (MME) detector. In contrast to the asymptotic analysis reported in the literature, we consider a finite number of cooperative receivers and a finite number...
This paper adopts research methods of relative carrying capacity of resources, it regards Liaoning province as a research area and the whole country as a reference. The relative carrying capacity of nature resources, the relative carrying capacity of economic resources and synthetic carrying capacity of resources of Liaoning province from 1999 to 2008 have been calculated. This thesis draws from existing...
In allusion to the scale problem in AHP, this essay demonstrates the importance of the selection of scale system and the necessity to evaluate scale. Through experiment, the essay points out a meaningful conclusion, that is, in reciprocal scale, index scale is more reasonable than any other scales. Although the method in this essay has some error, it makes some difference to the accuracy of the analysis...
The investment in Intelligent Residential Communities (IRC) has become one of the current highlights in the construction industry in China. The most important task that faces real estate developers and owners during investment decision-making is how to select a design option that would optimize the value of IRCs within a limited budget. In order to tackle this task, using Value Engineering (VE), this...
A large number of non performing assets in financial institutions is an important reason for causation and deterioration of financial crisis. Asset securitization is considered the effective way to deal with NPA. The key issue of restricting securitization is the selection of NPA. Firstly this paper introduced definition and market players of asset securitization. Secondly, it put forward the principles...
It is very important to determinate the objective system priority that affects the realization of project general objective. In this research Analytic Hierarchy Process is introduced into analyzing the relationship of three objectives from the questionnaire data collected by the experts. Priority of three objectives is identified, which is the quality as first, time and cost next. The result of this...
The paper firstly introduces the basic ideas of Analytical Hierarchy Process (AHP) and fuzzy sets. Since project risk assessment is too complex to be understood quantitatively only, conventional AHP did not truly reflect human cognitive especially those “fuzzy” properties. Therefore “fuzzy Analytic Hierarchical Process (fuzzy AHP)” methodology is designed for the project risk assessment. Based on...
Security of identity authentication in mobile-commerce system is a very important task, and its safety assessment is especially complicated. The Analytic Hierarchy Process (AHP) is an effective tool on transformation of question from half-qualitative and half-quantitative to quantitative. In this paper, applies AHP method to the safety assessment, establishes an index system according to the international...
To vehicle development problem, setting development targets is mainly based on the benchmark test data of competitors. Usually, the target setting is subjective and ambiguous. To reform the method, fuzzy decision-making matrices were established based on Analytic Hierarchy Process (AHP), hence, the comfort targets were set quantitatively. Then, the improved radar chart was used to make comprehensive...
Recently, the performance evaluations of raid manufacturing systems (RMSs) has become more and more crucial, because it is the foundation for investment and implementation of RMSs. However, due to various complex and vague factors involved in RMSs, it is hard to evaluate exactly. To measure a RMS roundly and objectively, a multi-level fuzzy comprehensive evaluation approach based on analytic hierarchy...
The index system of emergency risk evaluation on city bidding for large-scale sports events constructed by Delphi method, combining analytic hierarchy process method with subjective scoring method based on entropy weight to evaluate it. Adopting numerical to validate matrix, the effects of it provide decision-making method for decision makers, reduce decision-making risks.
During the process of building influence diagrams for real-world decision analysis, the most challenging task is probability elicitation from domain experts. Many human experts are used to describing probabilities by verbal or other inexactness expressions. It is hard for them to directly provide numerical probabilities. In this paper, we deal with this issue by using the Group Analytic Hierarchy...
Based on the fuzzy probability theory of the third kind of fuzzy events, a new multi-objective optimization model of fuzzy probability is developed. And the application procedure of the fuzzy probability model is illuminated in detail. In order to assess index weighted value scientifically, the analytic hierarchy process (AHP) is introduced into the fuzzy weighted values to avoid the uncertainties...
Decision-making systems intend to copy human reasoning which often consists in eliminating highly non probable situations (e.g. diseases, suspects) rather than selecting the most reliable ones. In this paper, we present the concept of class-rejective rules for pattern recognition. Contrary to usual reject option schemes where classes are selected when they may correspond to the true class of the input...
Under the Value-at-Risk (VaR) criterion, this paper studies on the value of information and solution for two-stage fuzzy random optimization problems. First, the value of perfect information (VPI) in VaR criterion is discussed by studying the difference of the wait-and-see (WS) solution and the here-and-now (HN) solution to the two-stage fuzzy random programming with VaR criterion. Then, the value...
This paper presents a decision support tool for the effectiveness of a Quality Management System (QMS) in a company. To develop this tool, a new approach PAHP based on the combination of the Pareto Optimality Concept (POC) and the Analytical Hierarchy Process (AHP). This approach is used to model and optimize the multi-objective function of real company which presents a major problem for controlling...
Adapting resource management, for vague environments, in wireless communication proved to be a measure point of research recently. In this paper we present a system that is capable of adapting some important resources (type of modulation, code rate and number of subcarriers) for blurred channel conditions. The system in this work is mainly designed for WiMAX, which proved to be one of the prominent...
In business or in daily life, people are always faced with various chances and challenges. How to discover an emerging chance from some possible chances for decision making is still a problem for human beings to solve. This paper presents an effective method to deal with this kind of problem. Based on domain experts' experiences, the possible factors influencing chances are obtained. And then the...
This paper proposes a cognitive model of shipping investment expertise by Analytic Hierarchy Process (AHP) approach and judgmental process survey. Assessment of shipping assets is a complicated task includes both financial and technical aspects and requires high degree of expertise particularly for technical evaluation. As a supporting tool, a fuzzy extended AHP structured is designed by collecting...
With the rapid development of the Third-Party Logistics (3PL) in China, it is very important to evaluate 3PL service providers based on an effective and implementable model. In this paper, we propose an Analytic Hierarchy Process (AHP)-based decision support model for evaluating 3PL service providers on a logistics platform. The platform offers comprehensive services for both 3PL service providers...
