Existing clustering algorithms need to specify the number of clusters and to select initial points using human input, which lead to inferior clustering and optimisation outputs. Here, an improved grey decision-making model based on the thought of affinity propagation algorithm and grey correlation analysis is proposed to solve these problems. According to the panel data class and the inter-class candidate...
For the multi-index decision problem with uncertain information, this paper introduces the definition of interval distance of three-parameter interval grey number, proposes the relative degree of grey incidence based on interval distance of three-parameter interval grey number, constructs the grey incidence decision-making model with three-parameter interval grey number, measures the relative degree...
This paper uses the data envelopment analysis method (DEA) to compare the efficiency of state-owned commercial banks, joint-stock commercial banks and urban commercial banks with 16 listed commercial banks in 2016, and points out the problems of commercial banks in China, and then put forward some suggestions.
Aiming at the problem of expert weighting in group decision making, an expert weighting method based on D-S evidence theory is studied. Three ways such as the distance, grey correlation and the combination of these two methods are used to measure the deviation degree of the experts' opinions on the scheme, construct mass function based on this, and uses the D-S synthesis rule to carry on the information...
Neurons forms interconnected networks to process information. In brain such networks are implemented for the purpose of computation or decision making. Neuron cultures on Multi Electrode Array gives advantage to study the network topology of network of neurons as it facilitates recording from population of neurons. Spike train recorded from the dish is used for analysis of the information content...
This paper aims to study the correlation between Atanassov's intuitionistic fuzzy sets (A-IFSs) obtained as image of strong intuitionistic fuzzy negations. We consider the action of strong fuzzy negations in order to verify the conditions under which the correlation coefficient related to such A-IFSs and their corresponding conjugate constructions are obtained. We attempt to present algebraic expressions...
In MCDM problems some criteria (attributes) having different importance are used to determine a best alternative from many. Thus, different weight methods exist in literature to evaluate the importance of each criteria. In this work TOPSIS, multi-criteria decision making (MCDM) method is applied using crisp data set with different techniques of weight proposed in literature. Therefore, intuitionistic...
During the groups of decision making progress, according to the preference requirement that decision-makers emphasized and the vagueness of the evaluation information, this article describes how to use a method based on two-tuple linguistic to rank the weightiness of the competitive intelligence evaluation indexes and convert qualitative assessment to quantitative evaluation. Using this method, the...
As some problems existed in the college teaching quality evaluation, a research method is proposed. At first, a set of index system suitable for college teaching quality evaluation is constructed. Then, the method of triangle intuitionistic fuzzy numbers of multiple attribute group decision-making, improved TOSIS method and gray correlation theory are introduced to college teaching quality evaluation...
There are many methods in statistical analysis, but the basic approach is quantitative analysis. Statistical analysis requires a combination of quantitative and qualitative analysis. Qualitative analysis is fundamental, and a quantitative analysis, which is the core of statistical analysis, is based on the precision of the qualitative analysis. The process of statistical analysis includes qualitative...
Improving the utilization of resources and service qualities, and reducing the system energy consumption are two important goals of dynamic virtual machine management in cloud computing. Nevertheless, the reduction of energy consumption is inconsistent with the improvement of resource utilization. In order to get the balance, a new multi-objective decision-making method of virtual machine placement...
Based on the upper echelons theory, the research analyzes the effect of demographic traits of entrepreneurs on financing constraints of SMEs with the hierarchical linear models, which samples 530 Chinese listed SMEs from the year 2010. According to the results, it is found that different demographic traits of entrepreneurs have different effects on the financing constraints of SMEs. Specifically,...
The essence of different modes of operation of the project lies in the difference of the outsourcing modes between owner and contractor. A better solution model is established based on the two typical characteristics of complex project outsourcing decision-making process-autocorrelation of the evaluation index and the flexibility of the owner's demand targets. To avoid improper expression and calculation...
The interface design of software used on Home Appliances targeted at satisfying passenger's physiology and psychological needs when operating the machine to the maximum extent is a complicated synthetic topic which embracing ergonomics, visual communication design, user experience design, behavior psychology, cultural studies of the consumer, optics and Chromatics and so on. So, it is very difficult...
In the oil price soaring, low pow's tap the latent become the focus of attention. According to the low pow mining data, and by employing grey correlation analysis and the maximum entropy technology method to pumping well swabbing parameters as the main data source, and to select a set of suitable for oil well mining production parameters, realize the optimization of oil well production plan for oil...
Selecting the most suitable Multiple Attribute Decision Making (MADM) method for a given MADM problem is a challenge for the decision maker. When there are several suitable MADM methods available for the problem, the challenge is even greater. We present a novel MADM method selection approach based on the Spearman's rank correlation. The approach will help the decision maker in selecting the most...
Attempts to test the impact of different boardroom characteristics relative to Triple-Bottom Line (TBL) performance in Malaysia has been limited. This study will offer such insights using a relatively new dataset from the Asian Sustainability Rating Index 2009. Using correlation tools, the study found no relationship between board characteristics and TBL performance, thus, this suggests that alternative...
The factors of high-new-tech enterprise R&D project investment risk were relevant and had Multi-stage, this paper used the method of experts consultation to find the evaluation indexes out, constructed evaluation indexes system of high-new-tech enterprise R&D project Multi-stage investment risk based on Life cycle of enterprises, evaluated the high-new-tech enterprise R&D projects with...
According to the diversity of software development risk, the complication of evaluation indexes and the comprehensive evaluation hardly with the present evaluation method, the software development risk was divided into three grade indexes. 13 risk evaluation indexes were constructed based on the different stage of real situation in the course of software development. Based on the grey decision-making...
Assessment of credit risk plays a dominated role in business decision making. Based on gray system and applied statistics, the improved GRA is developed to evaluate credit risk. Firstly, each level index's weight can be calculated by integrating AHP with variation coefficient in order to lessen deviation of sole method. Secondly, the principle and procedure of modified GRA based on TOPSIS is expressed...
