Countries described as ‘fragile states’ need timely sustained assistance to help rebuild basic infrastructure and institutions. However, with available funds becoming limited and number of ‘fragile states’ increasing, competition for such assistances have also become intense. To select countries for the fragile states support facility, a number of unquantifiable criteria are used by the African and...
Interval-valued intuitionistic fuzzy preference relation is a useful tool to express decision maker's interval-valued intuitionistic fuzzy preference information over criteria in the process of multi-criteria decision making. How to derive the priority weights from an interval-valued intuitionistic fuzzy preference relation is an interesting and important issue in decision making with interval-valued...
On account of the financial risk, with which is be faced in the process of the university education funding channels. It expounds the background and reason of the financial risks in colleges and universities, analyzes its components, proposes the principle of evaluation system, sets evaluation system, and explores the feasibility of carrying through fuzzy synthesis evaluation, establishes the mathematical...
Reasonable choice of logistics center location, has important significance, for optimizing the regional industrial layout, and promoting the development of modern logistics industry. For the problems such as the logistics center location by many influence factors, the decision-making and evaluation of location program are complex, this paper use the rough sets method to study. first, analyze the influence...
Demand forecast of emergency material is the precondition and foundation of planning emergency material storage strategy. Because of the emergency logistics have the characteristic as follows: sudden, uncertainty, non-conventional, the weak economy, complexity and so on, On the basis of defining the fuzzy condition and fuzzy transfer probability, the paper divides the emergency material demand into...
For the past decade various kinds of employer evaluation activities have been on the rise, but almost all of them are short of the guidance of scientific and effective employer brand competitiveness evaluation system. Therefore, this essay attempts to develop the employer brand evaluation system by taking consideration of two dimensions: social recognition and employee satisfaction, firstly utilizing...
Predicting oil price movements is very important for investors. Fuzzy time series which combine people's subjective attitude and objective history values can help people to solve forecasting problems. It has been applied to many areas such as stock index, university enrollments, exchange rates and tourism forecasting. This paper brings fuzzy time series into short term crude oil price forecasting...
With the economic globalization and the market competition intensifies, market require the production system increasing by the product. On the basis of clear customer needs and business requirements, it's essential for a production company, which wants to gain a competitive edge and to ensure the effectiveness and sustainability of production systems competitive, to formulate a correct strategy for...
Because the risk factors cannot be accurately measured it is very difficult to evaluate the risk of supply chain. By introducing hesitancy degree into the risk evaluation process, an intuitionistic fuzzy model is developed to describe the problem. With this model, an algorithm is proposed to evaluate the risk of supply chain. Example shows that the proposed method is superior to the existing ones...
This paper uses fuzzy average statistics analyze the questionnaire of participant situation for university students in the capital market. We find that fuzzy sample mean, fuzzy sample mode and fuzzy sample median could describe the fuzzy investing behavior of the university students and its average trends. The investing decision of the college students is not related with their gender and bone place,...
Information security is very important to a system. For strengthening the security of a system, we should control the risk in a low level which may need proper evaluation method. In this paper, an integrative method of multi-level fuzzy-gray evaluation was proposed to solve the problem that it is difficult to evaluate the information security risk with quantitative assessment. At last, an example...
The convergence theory is a basic theory of fuzzy mathematics and have very important applications in economics, management science, information technology and computer science. In this paper we introduce the notions of fuzzy PS-upper limit, fuzzy PS-lower limit and the fuzzy PS-convergent nets of fuzzy sets. We also study the properties of fuzzy PS-upper limit, fuzzy PS-lower limit and the fuzzy...
Nowdays, the bidding competition is more and more fierce, and the bid evaluation is influenced by many factors, but there are so many subjective factors in the traditional methods that they can not make quantitative analysis objective. So this paper try's to use the Fuzzy AHP in bid evaluation, and establishes the index system of the bid evaluation, then the weight of index has been set up by the...
This paper lets the Fuzzy mathematical methods combined with the AHP, establishment multi-level fuzzy comprehensive evaluation method based on AHP, at the same time combined with the characteristics of knowledge management evaluation index system, the Application of Fuzzy Synthesis Evaluation Method t in knowledge management, to make studies more feasible and practical.
China's credit environment context of ambiguity, it is difficult to quantify the characteristics of a fuzzy language assessment Based on the scale and gives the corresponding expression of triangular fuzzy numbers, while the export generalized ordered weighted averaging (GIOWA) operator to the assembly, and calculates the evaluation results. Based on the credit environment, the social credit environment,...
The topic of tuition fees has recently sparked heated discussions in various media. Based on China's national conditions, this article collected elevant data, such as national student average funding, training costs, household disposable income and did the quantitative analysis for tuition standards of several types of schools, then built a Multi-level fuzzy evaluation model, which regarded the tuition...
Efficient Store Management is one important strategy of Category Management, how to get the character of the store and how to classify the stores is the aims of this study. Using the Association to find the goods selling knowledge, building the similarity matrix, and applying the Fuzzy Cluster to classify the stores, so the special promotion to different type of store. The Precision Marketing is realized...
With the development of the market economy and the richness of the accounting content, audit plays an increasing important role in exposing the economic data errors and fraud and safe guarding market order. But owing to the objective existence of operating risk and limitation of audit technique, audit risk is inevitable to some extent. In this paper, fuzzy comprehensive evaluation model and the combination...
This paper studies how to calculate the difference between two intuitionistic fuzzy sets (IFSs). A new property of distance measure on IFSs is proposed at first. Some new distance measures on IFSs are proposed secondly. These new properties and new distances measure can be used in pattern recognition, and the new distances measure is more flexible as the decision-maker can set different weights according...
Employment competition is becoming increasingly fierce nowadays, so it is essential that the individual human capital relative value of college graduates be evaluated which provides some reference for the divergent selection between graduates and enterprises. This paper designs the corresponding evaluation index system on the basis of theoretical analysis, and then the fuzzy comprehensive is applied...
