With the coming of network economy, it brings a new chance for enterprises to form virtual R&D team. By utilizing the advance network and information management system, virtual R&D team can be setup without the geography limitation. Intellectual property sharing is one of important aspects in virtual R&D team, but the loss of intellectual property will also be a threat to the existence...
The K-NN query algorithm is a widely used algorithm in the spatial database, effectively carrying on K-NN query algorithm has become the focus problem of the spatial database, the traditional query algorithm will adopt the measurement distance and pruning strategy to improve the query performance by using the tree index, it needs to carry on a large amount of distance calculation to exclude the unnecessary...
Reference to the related research and the arrow theory model, the index system of the competitiveness of the special equipment manufacturing industry is built. Based on the technique for order preference by similarity to ideal solution and the entropy weight method, the model of the competitiveness of the special equipment manufacturing industry is built. The competitiveness of the special equipment...
Illustrated with Qiantang estuary , Hangzhou Bay, the relationship between structure of coastal geomorphology and dissipation of tidal energy were analyzed and the landscape ecological mechanism of watershed flood was studied based on the theory of the landscape ecology and quantitative assessment method of landscape characteristic index. By Correlation analysis and multiple linear regression analysis...
Pig industry plays a very important role in adjusting agricultural structure, promoting the optimization of the agricultural resources allocation, improving the people's livelihood and increasing farmers' income. But in recent years, price of pig fluctuates violently. As a result, participants within the pig industry have frequently found themselves facing increased variable and more price risk. Sharp...

With the advance of China's energy-saving strategy, building energy conservation is progressing gradually. Does it help or is it effective? In response to this question, we need to establish a set of evaluation index system with scientificity and practicability.
As a means of continuous improvement for the existing process, 6σ is more and more popular to enterprises. The purpose and the main implementing methods in all phases of DMAIC model of 6σ are introduced. The difference between the process capability index and the process performance index is analyzed. The significance of the application of process capability analysis in measurement phase is discussed...
Gray evaluation, a method which combines semi-qualitative with semi-quantitative, is very effective to the index of the core competitiveness which can not be measured. According to the theory of core-competitiveness and the characteristics of coal enterprises, this paper constructs an evaluation index system of core-competitiveness of coal enterprises, and makes a model of multilevel gray evaluation...
Based on the analysis of the importance of project termination decision and the review of related research, this paper constructs an R&D project termination decision model based on Kohonen neural network consisting of the principles of a system of evaluation indexes, the quantification of eigenvalues of the evaluating indexes, the basic principle of Kohonen and the establishment and application...
Financial competitiveness is the embodiment of the company competitiveness. It is important for investors or company itself to evaluate the financial competitiveness. In this paper, a financial competitiveness evaluation model based on the method of analytic hierarchy process (AHP) was built which includes 15 indicators in four areas of solvency, operational capacity, profitability and development...
Coordinated development of resources, environment, economy and society in Henan province during the years of 1990-2007 as an example is made by empirical research. Conclusions such as physical capital investment and energy are important input factors, the utilization of number of employed persons is low, and inputs of resources and the environment made inadequate contribution to the social system...
By use of power system analysis software the operation to voltage collapse was simulated. Variance of voltage amplitude , phase angle, active power ,reactive powerwere figure out in each node. Simulation data were used to simulate PMU practice measure data . According to P and Q decoupling relationship of power flow equation , in jacobian matrix were solved. As voltage stability indexes were used...
This text applies relevant theory of the quality cost to the management of quality cost of the channel and then based on relative theories of fuzzy decision improving AHP in order to appraise every index of the system of the Channel quality cost and solves the problem of the empowerment.
In order to solve problems of confused evaluation and weak guidance in small and medium manufacturing enterprises, a maturity evaluation model concerning the information capability of business process is proposed, which is based on the completion of core indicators at all levels of information technology. Firstly, based on the existing enterprise information model and related theories, a target evaluation...
In order to cope with climate change and global warming, cities and many international organizations actively promote the construction of low-carbon city, which needs evaluation mechanism to support related policies. Based on the theory of fuzzy rough set, this paper constructs the evaluation model and index system of urban low-carbon economy comprehensive evaluation from five aspects include economy,...
Basing on the analysis of the current performance evaluation index system , this paper put forward that performance evaluation index system should be made to EVA as the center rather than to net income for the center because only the EVA is the measure of corporate value and wealth creation metrics . performance evaluation index system of the company of EVA-based includes corporate objectives and...
This article used the multi-level fuzzy quality synthetic evaluation principles to evaluate a Beijing enterprise's culture construction. Screening a representative building of enterprise culture a total of 21 indicators of four main types of fuzzy statistics and then use the set-valued iterative method gives the weight for each indicator, using multi-level fuzzy comprehensive evaluation of the technologies...
The paper establishes the evaluation index system of resource allocation in S&T. The method of DEA is adopted here to evaluate not only the technical efficiency of fiscal input in S&T in different regions and economic growth but the co-efficiency of the technique and the scale on the basis of the data in 2006 of the fiscal input in S&T in 31 regions and the economic growth.
This is an empirical analysis of the regional differences of the influencing factors of technological innovation based on panel data of China's 30 provinces. It highlights not only R&D investment, but also government support, financial support, technology spillover effects of FDI, transition of regional economy, human capital and other factors. The empirical results show that, R&D investment...
