To identify the performances of an aeration equipment, it is necessary to determine some parameters which helps to classify it from the hydraulic-technical-economic point of view. Current methods compare mechanical equipment to hydrodynamic parameters. The most important parameters are the oxygenation capacity, CO [kgO2/h], the economic coefficient, E [kgO2/kWh] and the specific power index, δ [W/m...
Existing research on layout of the marine industry is still at a scattered exploration stage, and results calculated with a relatively mature grey correlation method indicate that China is divided into three major industrial correlation regions with Shandong, Shanghai and Hainan as the core respectively while marine departments are still lack of correlation among them. According to calculation results...
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...
Timber Purchasing Managers' Index (PMI) has been perceived as the barometer of timber industry evolution. The weight scheme is at the core of constructing the index. In this study, an in-depth analysis on the weight scheme of Timber PMI is conducted. The empirical results reveal that the current weight does not affect the leading function of Timber PMI, but it is not the optimal weighting method....
Sustainable development requires the transformation of societies into knowledge societies. ICTs are increasingly becoming repositories of knowledge and information, which has implications for the field of knowledge management. In this paper, we attempt to conduct a preliminary analysis to identify the factors that influence the sustainability of knowledge societies. A Knowledge Societies Index (KSI)...
Scientific and accurate cultivated quality grade results are an important guarantee for applications. However, the phenomenon of abnormal cultivated land quality is always occurred due to the error of investigation or computation, so exploring effective method to inspect abnormal data of the grade results is an important problem to be solved. Cultivated land quality grade results of Wuhan Hannan district...
Beichen district of Tianjin, located in the important node of Beijing-Tianjin golden corridor and high-tech industry area of Jingjintang region, has strong industrial foundations, while it is still faced with the problems that traditional industries account for high proportion of the industrial structure, inefficient use of industrial land, lack of enterprise innovation ability and shortage of resources,...
As the important factors affecting the economic growth, system innovation and technological innovation have been widely attended. But there is little quantitative research on them. According to the theory of grey correlation analysis, this paper calculates the contribution degree to the economic growth through 10 indexes which can measure the system and technological innovation from 2005 to 2014....
Evaluation of construction or renovation projects is necessary for the developing of distribution network. A comprehensive evaluation can contribute to find problems in the process of projects and promote scientific level of decision making for future construction or renovation. In this paper, we propose a post evaluation for distribution network. Firstly, we put forward an integrated index system...
This paper selects the time series dates in 1995–2013 about total output value of the high technology industry and the sum of the import and export trade in Jiangxi province. By ADF test, Johansen test and Granger causality test, we studied the relationship between the high-tech industry and the import and export trade. Studies have show that in Jiangxi province the high technology industry has a...
Training effect evaluation is an essential step of enterprise training management. The article, by introducing the evaluation index system, attempts to evaluate enterprise training effect with grey correlation analysis method. By empirical analysis of an enterprise, it analyzes the staff training effect with the evaluation result, and further assesses the enterprise training effect. Accordingly, the...
Selects the invention patent applications as measures of China's innovation capability, utilize the characteristic index of patent influence factors. Based on type B grey correlation between two of which to calculate and determine the Lag and index weight of influence of different characteristics of the indicators on China's innovation capability. On this basis, calculate the regional innovation capability...
With the accelerated process of economic globalization, inter-regional linkages are becoming closer, exchanges become more frequent, spill over effects of public services are increasing day by day. In this paper, the author analyzes the level of public services in the provinces spatial correlation by using the theory of spatial economics. The results indicate that the level of the supply of public...
Under the new historical condition, strengthening the communication and popularization of science and technology is both the requirement to implement the national development strategy and need for social development as well as the basis and key point for the development of popularization of science itself. Relevant data of five characteristic indexes, talents, funds, place, communication and activity...
This paper evaluated the innovation capacities of Shandong Province and Guangdong Province quantitatively using the regional innovation capacity evaluation system. Then the author compared different innovation degree associated with local economic growth using gray correlation theory. Finally this paper presented several suggestions of improving innovation capacity.
This paper will establish a reasonable evaluation index system and research method as a solution of main problems. First of all, according to the specific problems on solar house design, evaluation index system is constructed, Then, the idea of integrating the AHP method and the intuitionistic fuzzy entropy method is proposed to determine the weight coefficient of each index; Finally, using the grey...
As an important source of logistics demand, the manufacturing industry played a role as demand promoter for the logistics industry. At the same time the level and extent of the development of the logistics industry directly related to the efficiency and effectiveness of the manufacturing enterprise. It is the key to improve the core competitiveness of enterprises. Based on the data of Dongguan logistics...
Using 1-min transaction data, this study investigates the relationship between volume and volatility in CSI 300 futures market in China. Unit root test indicates that return series are stationary. LB-Q and ARCH-LM statistics confirm volatility clustering and time-vary volatility. ARMA (2, 2)-EGARCH (1, 1) model find evidence of GARCH effect, and positive shocks have a greater impact on volatility...
With the reform of economic system in our country, the internal and external environment of listed companies has great changes. The performance management pattern is also changing. Listed companies play an important role on our country's economy, so their performance management modes are significant. This paper, through analyzing the performance evaluation modes, constructs the performance evaluation...
