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...
In this paper, we use grey control system's thought and economic control theory to define seven kinds of grey control operators and their calculations. We prove that these seven kinds of operators have good characteristics. Furhermore we conlude them into two basic operators: proportional operator k and grey differential operator D. According to the topologiacal relations of research universities...
Supply chain coordination for short-life-cycle products with price-dependent demand is a focus in present operation management and management science fields. This paper considers a supply chain coordination problem for a single-cycle and two-selling-stage short-life-cycle product. Firstly, the inventory model of whole system is depicted with a stochastic dynamics programming. Then, a combined contract...
There exists uncertain in almost problems of our practices and the uncertain hold back decision-maker cannot accurately define indices values when they evaluate the system. For this problem, present decision-maker often defines an interval number to denote this index value, but none has studied the interval number decision model in grey target decision. In this paper, the distance of the interval...
Based on the complexity and uncertainty of regional urban spatial structure assessment, the paper has set up goals of regional urban spatial structure optimization and constructed index system for assessment. Applying Gray group decision-making theory to assess urban spatial structure optimization system, we have assessed different towns' spatial structures resulting in the effective information for...
The model of GM(1,1) is one of the most important sections in the gray system theories. The abilities of reaction, which the original sequence data are simulated by the GM(1,1), are always noticed by many scholars. However, it is stopped in evaluation of prediction errors in one or two examples that the problem is researched in the present. In this paper, the abilities of GM(1,1) simulation for non-vibration...
For long time, the rationalization of distribution scientific and technological elements has been important issues of the regional coordination development. 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, environmental bearing capacity, system constraints extent and the amount...
All types of information about the comprehensive evaluation on nonprofit organization's (NPO) performance is often fuzzy and grey, so simple fuzzy evaluation or grey evaluation methods could not evaluate the real performance of NPOs objectively and accurately. This paper applies grey fuzzy comprehensive evaluation on the performance of NPO, and makes an experimental analysis on a private vocational...
It is very important to predict Chinese logistics scale in 10 years for drawing up the macroscopic economic policy and promoting economic development. With the grey system model GM( 1, 1), predicting Chinese logistics scale in 10 years can reflect the development scale of logistics in the future and can offer decision base on planning a national logistics industry and making logistics policy according...
The most fatal flaw of the classical Cournot oligopoly model as well as the related oligopoly output-making competition model is the supposition on the purpose of game players, which holds that the only game goal is to make the present profit maximum. Based on this supposition, most game model structures are optimal structures. In this article, some new suppositions of duopoly game are established,...
A rough analysis method based on extension of rough sets is proposed for handling multi-attribute decision making problems with preference and incomplete information. Firstly, the concept of generalized extended dominance relation is presented; secondly, the rough approximations of knowledge are obtained by generalized extended dominance relation and decision rules of classification are acquired;...
Aiming at the shortcomings of studying on Science & Technology productivity that only limited to qualitative analysis in academia for a long time, the author, by applying the control theory, constructs a productivity control system for country and region, which involves various production factors as the input and the contribution made by science & technology to GDP (science & technology...
Rationality of index weight designing is one of the most important factors which relate to whether the result for one of multi-object evaluation problem is correct or not. However, weights got from the major objective weight methods at present are all excessively highlighted separating capacity of the index, but neglect the importance and contribution for the evaluated object. Because of these above,...
For a long time, how to put optimal allocation of counterpart fund into new technology import according to its regional external effects, has received great attention from the manager and the experts on government management. On the base of Endogenous Growth Theory, a production function model of endogenous counterpart fund for technology import is built on this paper. Moreover, taking maximum production...
Aimed at the traditional grey incidence model has multiple infection from the horizontal and vertical coordinate of the curve, the author bring forward the periodic relationship model and have the conclusion that the model is only in reference to the period of the wave, but is independent of its swing, and can show the positive-negative relevance, at last the author validate its practicability with...
