The reservoir immigrant is a great quantity of, organized and non-voluntary population migration caused by the construction of reservoir in the development of water resources use process. The appraisal of reservoir immigrant is aimed at the effect of the reservoir immigrant, which involves the aspects of the society, the economy, the resources, the ecology, the environment and so on. This appraisal...
From the angle of the traditional energy assessment, the fuzzy probability theory is applied to appraise the green energy. Firstly, the influential factors of the green energy assessment for energy project are analyzed according to China's national conditions. The factors of energy project are divided into four parts, such as absolute cost, ecological harmony, energy security and sustainability. The...
This article used the multi-level fuzzy quality synthetic evaluation principles to evaluate a Beijing enterprise's culture construction. Screening a representative building of enterprise culture a total of 21 indicators of four main types of fuzzy statistics and then use the set-valued iterative method gives the weight for each indicator, using multi-level fuzzy comprehensive evaluation of the technologies...
Due to the features of unconventional emergency itself, “Scenario-Response” is regarded as a more effective emergency management mode to unconventional emergency. The whole process of disposal assessment is an important basis for relief decision. This paper describes the scenario-based assessment of whole unconventional emergencies disposal process (pre-disposal, the medium-term disposal, post-disposal),...
Measuring the performance of a given classifier is not a straightforward or easy task. Depending on the application, the overall classification rate may not be sufficient if one, or more, of the classes fail in prediction. This problem is also reflected in the feature selection process, especially when a wrapper method is used. Cohen's kappa coefficient is a statistical measure of inter-rater agreement...
At present, recycling of the household appliances has become a global common problem of resources reuse, and it is necessary to establish a system of household appliance reverse logistics. This paper selects three major aspects: economic benefits, management level and social benefits, then uses Analytic Hierarchy Process (AHP), 360-degree feedback method and fuzzy comprehensive evaluation method to...
This paper investigates forecasting accuracy of fuzzy extended group decisions for adjustment of statistical benchmark results. Delphi is a widely-used method for implementing accurate group consensus decisions. However, the concept of consensus is subject to expert characteristics, and sometimes it is ensured by a facilitator judgment. Fuzzy set approach is adapted for Delphi, named fuzzy-Delphi...
At present many enterprises are doing various technological innovation ability appraisal, they all intend to take advantage of this to propel the enterprises' technological innovation, but we must make sure the appraisal method is scientific, feasible and standard, also the degree of efficiency and authenticity about the appraisal result should be well. In this paper, the application of multi-level...
In this paper, we propose a new diagnostic checking tool for fuzzy rule-based modelling of time series. Through the study of the residuals in the Lagrange multiplier testing framework we devise a hypothesis test which allows us to determine if there is some left autocorrelation in the error series. This is an important step towards a statistically sound modelling strategy for fuzzy rule-based models.
As the development of technology, the enterprises of our country have came into the stage of all-round risk management. But there are still many problems in the initial stage of risk management about thermal power plant projects. This paper brings forward the concept of initial risk evaluation about constructive projects in thermal power plant, puts forward and builds the evaluation index system for...
Green credit policy as a new standard for bank loan has been known by more and more people. It is not only a new method to avoid bank's risks, but also a new measure to promote energy-saving, emission reduction and sustainable development. More qualitative analysis of green credit has been done. Yet, through the method of analytic hierarchy process (AHP) to ensure the weights of each index and setting...
Summary form only given. There is an extensive literature on decision-making under uncertainty. Unfortunately, up to day there are no valid decision principles. The widely used principle of maximization of expected utility has serious shortcomings. The first approach in classical theory of choice was formulated axiomatically in the expected utility theory of von Neumann and Morgenstern and is the...
Coal bed methane (CBM) potential evaluation is important for choosing the prospective target area for CBM exploration and production. Many unwise evaluations may have induced the high failure ratio of CBM exploration and development in China. Developing a comprehensive model for CBM potential evaluation is also complicated by the diverse geologic and engineering factors. In this paper, a fuzzy analytic...
In the course of constructing service government, service concept should be formed and service quality should be improved. On the basis of customer satisfaction theory, this paper researches on enterprises' satisfaction to the economy and trade board in Yiliang County by developing a questionnaire. At the first, this paper reviews literature about customer satisfaction. Secondly, it designs index...
We discuss the historical perspective of concepts of fuzziness and randomness, with emphasis on fuzzy random variables. We will describe the analysis of the interpretation, modeling, and impact of fuzzy random variables. Examples will be given of scenarios modeled by fuzzy random variables. Also, main approaches using fuzzy random variables will be discussed. The theoretical concept of expected value...
This paper presents an approach by considering fuzzy parameters in simulation model to obtain fuzzy throughputs in manufacturing systems. The basic subject of simulation is the probabilistic approach to describing real world uncertainty. However, in many cases we do not have information that would be precise enough to build the corresponding probabilistic model or there are some human factors that...
The evaluation for competitiveness of product is a prerequisite for product decisions, so it has an important practical significance to evaluate the competitiveness of product. This paper applies Analytic Hierarchy Process to establish the evaluation index system for competitiveness of network product, and constructs a mathematical model to evaluate the competitiveness by multi-level fuzzy evaluation...
Aiming at disadvantages of fuzzy comprehensive evaluation (CE) in weight determination, according to rough set theorem and analytic hierarchy process, a weight determination method of complete data driving is presented, and improved fuzzy CE model is obtained. At first, evaluation index system is formed according to analytic hierarchy process. Then index system is reduced effectively by the use of...
Poverty, a permanent problem in the society, is listed top-class global problem of social development by the United Nations. Grading the needy situation of impoverished families helps the government establish better policies, distribute resources more reasonably, and therefore provide aid more effectively. However, the traditional single-factor mode is not adequate, for poverty grade evaluation involves...
Hierarchy model of real estate investment risk is established. Through using triangular fuzzy numbers and analytic hierarchy process, we have evaluated the risk of real estate, and identified the risk factors for the overall impact on real estate investment project.
