The evaluating index and assessment methods are very important aspects for the research of industrial international competitiveness. Therefore, this paper firstly summarized the types of evaluating index of industrial international competitiveness, including the achievement indicators and the reason indicators. Secondly, this paper expounded the advantages and disadvantages of the different assessment...
The vehicle distribution problem has been a NP problem for a long time; it can not reach a most optimized state. Because of the multi-factors that should be considered about the vehicle distribution problem such as the loading capacity, sources , the cargo categories and so on. So it can not to describe it with one or a set of math expressions. This article based on the Genetic Algorithm takes each...
Dimensionality reduction technology of high dimension data, projection pursuit classification (PPC) Model, was used to evaluate flood disaster. In the case of flood disaster loss without evaluating criterion or with inapplicable criterion, real-coded accelerating genetic algorithm (RAGA) was utilized to optimize the projection direction of PPC model, and then transform multi-dimension data to low...
At present, RFID is used in some practical fields such as supply chain management, stock management, and so on. However, for the cost reason, the RFID tags are not suitable for individual items, especially for lower-priced goods. In this paper, firstly, the features of logistical unit in the distribution are characterized, and its information is abstracted into a "tree" data structure. Secondly...
On the basis of the essential connotation of university financial risk and the basic principles of setting up an index system, the evaluation index system of the management performance on financial risk in university has been established. It evaluates the management effect with the method of. It provides a scientific, practical and quantitative method for the systematic analysis and comprehensive...
This paper introduced several abstract algorithms and analysed the existed problem, which the keyword's position was not enough considered in Lucene software package. Then this paper developed the dynamic abstract algorithm in Lucene software package. The new algorithm referred to the keyword's position in the content. The new abstract is exact. By testing, the developed algorithm is more effective.
In this paper, the authors investigate the phenomenon of mobility based on a random exchange model. Economic mobility is a supplemental index in evaluating and comparing inequalities with respect to wealth or income distribution. The dynamic characteristics of mobility can be fully exhibited by an agent-based model in which agents exchange money with each other, and the ranks of individuals always...
One of the most important benefits of ANN (artificial neural networks) is the free of the restrictions of the classic statistical techniques. Some literatures points to several limitations in multiple regressions that are overcome by ANN. This paper demonstrates the usefulness of ANN in customer satisfaction analysis and compares ANN and regression, based on data from a China company customer satisfaction...
Comparing with the IEEE 802.11 DCF mechanism, IEEE 802.11e Enhanced Distributed Coordination Function (EDCF) mechanism has been improved in many aspects for the increasing of the Quality of Service (QoS) in wireless networks. But there are still a few problems to be settled down in IEEE 802.11e EDCF backoff mechanism in which the transmission fairness should be improved further more. In this paper,...
An image retrieval based on texture primitive is proposed in this paper. The texture primitive is firstly constructed according to the principle of the block truncation code (BTC). Meantime, based on the analysis of the statistical distribution of the texture primitive, the spatial distribution map of each feature is presented to describe the image texture information. Experimental results show that...
This paper makes the empirical study on parallel imports in pharmaceuticals and social welfare. It shows that the regime of international exhaustion of IPRs and parallel imports of medicines can facilitate the optimal utilization of global resources and benefit more people in the world. Parallel imports can drive competition and make consumers obtain the pharmaceuticals at lower prices. It can bring...
In this paper, we investigate the statistical properties of fluctuations of Chinese stock index. According to the theory of artificial neural network, a stochastic time effective function is introduced in the forecasting model of the index in the present paper, which gives an improved neural network - the stochastic time effective neural network model. In this model, a promising data mining technique...
This study investigates investor relations related items on websites of listed companies in Shanghai Stock Exchange, Shenzhen Stock Exchange and Hong Kong Exchange. To compare the IR efforts situation of companies in these three markets, a website based investor relations index WBIRX is put forward. Then, by comparison, the study shows that, despite some fast progress, both in formats and contents,...
The research of groundwater vulnerability is the basic work to protect the groundwater. For sustainable utilizing groundwater resource, evaluating groundwater vulnerability is necessary .Useful reference to protecting, exploiting and utilizing groundwater resource are provided rationally. Three methods are applied to evaluating the groundwater vulnerability in Sanjiang Plain. They are the entropy...
This paper employs the DEA method to measure energy use efficiency in Chinese provinces from the perspective of energy-saving and emission-reduction. Concretely, an index that reflects energy-saving and emission-reduction is introduced to analyze a cross-section of data that cover 30 provinces in China. This index is more instructive in showing a measure of energy usage in different provinces, compared...
Bid evaluation is an important but complex problem in multi-attribute auction. Management science techniques might be helpful tools for this kind of decision making problems. This paper focuses on the bid evaluation problem in multi-attribute e-auction for procurement. The proposed model uses an outranking-based multi-attribute decision technique, ELECTRE-III, to evaluate the buyer's preferences....
Knowledge sharing, which is one of the most important factors of knowledge management, plays more and more crucial role in the process of the enterprise development. The topic of how to encourage the employee to deeply share their knowledge is the direction of knowledge management field. Base on the theories on knowledge management and knowledge sharing, by using the AHP method, a model of measuring...
Constructing and managing an information system (IS) is a highly complex and difficult system project. It is a problem which is needed to be solved that how to measure the value which is brought to the enterprise by IS and how to make IS bring more value to enterprise. The research's emphases is the IS in enterprise. It will focus on the measurement of value the IS brings to the enterprise even to...
The writer puts forward the concept of the carrying capacity of ecotourism system; analyses its feature and effect, and the content and the present situation on its study; constructs the framework of carrying capacity of ecotourism system and then studies the systematic effect and relevant indexes system. Thus it provides the theory and method for sustainable development of ecotourism.
Four knowledge production modes in China were divided in view of production management and their operation modes were pointed out; then, a fuzzy AHP decision-making approach was applied considering the complexity and uncertainty of knowledge production. In this approach, the evaluation index system and hierarchy model were established based on the analysis of influencing factors on knowledge production...
