The essence of traditional incidence model is incidence analysis based on the certain real, which can not handle incidence analysis among uncertain number sequences. This article gives a calculation model of grey absolute incidence degree between uncertainty sequence data based on interval grey number expression. The model can analyze the incidence degree of two interval grey sequences groups which...
This paper uses game theory, analyses the relevant enterprises and the government's different motives and the behavior of game in the process of the ecological industrial chain forming, then conceives the incomplete information dynamic grey game model and identifies the optimal strategic combination between the government and enterprises. Based on the analysis of the game, get the government and the...
By using the analyzing method of Grey Relational Entropy, this paper makes specific analysis of the elements which affected. Combined with the status of Shanxi investment environment, we can find the primary and secondary order of the specific elements. And it is easy for seeking the channels and countermeasures to enhance Shanxi FDI Absorption Capacity effectively by conducting in-depth analysis.
This article reviews the existing algorithm models of the grey incidence and finds that no method has the properties of normality and isotonicity synchronously, and then analyzes the corresponding reasons. Finally, it gives several study results.
Model of grey linear program is one of good methods on the process of finding the solution of grey matrix game. Studying interchangeabilities of grey mixed optimal strategy, we certify necessary and sufficient condition that there is grey mixed optimal strategy in the grey matrix game, which the grey game value between player 1 and 2 is equality in the grey saddle point. Based on these, we prove that...
Grey numbers can be represented as their kernels and associated degrees of greyness. Therefore, the operation between kernels of grey numbers has significance in the application of grey numbers. This paper investigates the operations of grey numbers using their kernels and degrees of greyness and provides conditions for the application of real number operations to their kernels.
A critical issue in case-based reasoning (CBR) is to retrieve a usefully similar case to the problem. There are three approaches to case retrieving: nearest-neighbor, inductive, and knowledge-guide. This article utilizes a hybrid approach using grey incidence theory to case-based retrieval process in an attempt to increase the overall classification accuracy. We propose a new approach based on the...
A gray input-output model based on the standard interval grey number, the condition of convergence of M steps grey matrix and the solution method were given, then produced the corresponding mathematics proof in this paper. The model and solution method obtained a good result in the solution process of the gray input-output model. Finally, the validity and feasibility of this model was confirmed when...
As Jiangsu province ranks in rapid economic development area in China, its electricity consumption gets an increasingly grow in recent years. It is meaningful and significant to forecast its electricity consumption tendency. GM(1,1) and GM(0,N) are applied to look insight into the tendency in the paper. The models have good accuracy. Through the models, we find that the electricity consumption of...
The GM(1,1) model assume the sequence is analogous to exponential law. Great error appears when it is used to simulate many nonlinear sequences. The paper proves that the growth rates of the simulated value of the GM(1,1) model and the discrete GM(1,1) model are both fixed value. If the growth rates of the primary sequence are equate, the fitted value deriving from the discrete GM(1,1) model the same...
According to the data of Chinese OFDI industry structure and its domestic industrial output structure during 2003 and 2006, the absolute degree of grey incidence, the relative degree of grey incidence and the synthetic degree of grey incidence are calculated, so as to analyze the influence of OFDI on domestic industrial structure adjustment. It is shown that there is a close relationship between the...
It is a typical economic rule that productivity of science and technology is allocated on different levels by the effect of technology elements, and the flow of scientific and technological is one of hot problems in academic circles. Based on the perfect mechanism, the paper establishes a linear programming model of effect of technology elements flow, under the restrict conditions of resources available,...
The extenics is one of the theoretic foundation for the artificial intelligence and the dependent function is one of the most important works. It describes the degree of the objectpsilas qualitative and quantitative changes, so its value should be satisfied with the general regularity. On the other hand, because the extension excellent analysis is very fit for the social and economic systems, it makes...
Grey judgment matrix is constructed based on the judgments of decision-makers by the thoughts and methods of grey system. The satisfying consistency of the grey judgment matrix is defined. Then a bunch of judgment matrix with consistency and its whitenization weight function are researched to solve the last weight of the grey judgment matrix. At last, an example is given to show the thoughts and the...
Grey incidence model determines the closeness degree from the closeness and similarity of statistical sequencepsilas geometrical form. Traditional grey incidence model calculates statistical sequencepsilas correlation degree from the perspectives of its acreage, slope, changing velocity, etc. These incidence models have dual influences exerted by horizontal and vertical coordinates. Subsequently,...
When the forecast model is to be established, the problem is often confronted that the more the sample data is, the worse the precision is. Based on the geometric sequence, the paper probes the influence on the error of the simulation value exerted by different sample numbers. The paper studies the relation between the growth rates of the primary sequence, development coefficient and the growth rates...
On the basis of (GAHP), this paper has improved the method of how to judge related factors which are important in multi-objective planning, and we came to a solution about the difficulty of judging accurately the importance of relative factors which are caused by the unbalanced distribution of information.
It is of great sense to correctly appraise the developing level of science and technology park. In order to make the appraisal scientifically, we need an index system and an evaluation model. In this paper, an index system for evaluation of the science and technology park of provincial level has been presented with grey system theory and Delphi Method. A new evaluation model based on trigonal whitenization...
Considered elements of input node and weight vector are interval grey numbers in Self-organizing Feature Map (SOM), normalized these interval grey numbers, defined the interval grey number Euclidean distance, and proposed Grey SOM (GSOM) model which can solve uncertain problems efficiently. In the end, we studied intelligent clustering of commercial bank off-site regulation empirically using this...
Undoubtedly scientific and technological talents play a vital role in social economic development, and the human resource's flow question also becomes the focal point to which the society pays attention day by day. This article uses evolution gambling theory to analyze the primary factor that influences scientists and technicians flow, and the evolution gambling model mainly expresses some entity...
