In view of the shortcomings of bore and section data-based modeling,, a new kind of data structure is proposed in this paper to describe three-dimensional geological body structure based on borehole data. Based on OpenGL library, the 3D geological modeling and visualization of complex geologic body were achieved in Visual C ++ 6.0. Experimental data test shows that the data-structure not only can...
This paper does an empirical research on school production efficiency of educational resource in chinese compulsory education, using the DEA model, Tobit model and other statistical methods. Results show that: (1) The school production efficiency of educational resource in the middle-eastern area of China is not satisfactory. Therefore, it is a feasible way to improve school production efficiency;...
Carefully designing service products is the foundation to improve the functional quality and the technical quality of service. Through the analysis of the generalized service product model, the paper finds the underlying dynamic process of service production, analyzing and constructing service production and marketing model based on the service production model of generalized service products from...
We explore capability during the process of firms'information technology adoption and implementation from organization learning perspective. According to the dimensions of absorptive capacity proposed by Zahra and George, we identify the main elements of firms' IT potential absorptive capacity, use structural equation modeling to take empirical test. The research indicates that five factors including...
Hi-tech enterprise is one representative business group in hi-tech field in China. Hi-tech enterprises have higher growth than other enterprises. However, under complicated and uncertain circumstances, their growth is influenced by many factors in every respect and the influences differ from one another. Based on the statistical data in 2010 CHINA TORCH STATISTICAL YEARBOOK, this paper uses multiple...
At first, we analyze the advantages about employing multilevel model in communication research. When it samples from different levels and units, the resultant data will appear stratification. Hierarchical data structure is common in communication studies. Audiences exist within hierarchies tend to be more similar to each other than people randomly sampled from the entire population. Therefore, multilevel...
This article analyzes efficiency in Chinese stock market based on the robust regression model considering serial correlation for the sample of daily return. We find that the Shanghai market has reached weak form efficiency, while Shenzhen market has not yet. We also analyze the impact of Price Limit Mechanism on market efficiency. The result indicates that the Price Limit Mechanism has reduced market...
Sale effort competition and capacity optimization in electronic markets happens familiarly in two manufacturers. Being a channel leader the first manufacturer's role becomes complicated which still owns a weakest traditional retailer at the same time. Focusing on channel sales effort effect, the paper finds out their optimal decisions, and conditions in which supply chain coordinates. The key study...
This paper adopt data of China's A-share listed companies, empirical test the relationship among company's profit, the degree of earnings management and earnings response coefficients(ERC). Research found: First, company's profitability can significantly raise stock return, which means ERC is significant positive. Second, the degree of earnings management can significantly influence the relationship...
Based on the P2P nodes with bounded rationality, the paper used replicate dynamics model of the nodes' strategies to simulate nodes' learning and strategic adjustment process in 3×3 evolutionary game. Paper analyzes the model's evolutionary stability and proved its validity by case studies and simulations.
With the overall development of China's commercial network planning, the scientific design of the planning will determine the healthy development of our urban business in the future. Based on the research of the requirements of the commercial network planning and by using the outstanding data analysis of GIS and its visualization presentation and its assessement of desion-making model, this essay...
As a kind of reasoning technique of artificial intelligence, case-based reasoning (CBR) has been successfully applied in many engineering field. Similar case retrieval is a key technology in CBR system. In order to improve the case retrieval efficiency, a case reasoning model based on gray relation and synthesize weight was proposed, applying the gray relational analysis in case reasoning and combining...
Enterprises have become increasingly dependent on online social network to carry out beneficial e-business model and achieve better performance. This paper aims to explain and demonstrate how an online social network environment where enterprise cooperative behaviors and interaction structures coevolve influence enterprise business model. By constructing components model of enterprise business model...
The theoretical calculation model for price-earning ratio (PE) is deduced through transforming the dividend discount model so as to find out the main factors affecting price-earning ratio in theory. Stocks of Shanghai Stock Exchange (SSE) 180 index are selected as the sample, and empirical study on the main factors affecting price-earning ratio is carried out based on the panel data during the 2005–2008...
According to the characteristics of group creative activities, group creative process was divided into five phase: initial preparation, individual conceiving and creating, group integration and creating, innovation program evaluation, program implementation. On this basis, combined with SECI Spiral model of knowledge creation, Conversion mechanism of four categories of knowledge including Individual...
Increasing professional human capital and making full use of the foreign capital is China's important action about industrial structure adjustment and upgrade. This paper, based on the unstructured vector auto-regression model, analyzed the professional human capital and use foreign capital impact on upgrading the industrial structure in China. The results suggest that increased professional human...
This paper firstly analysis the feature of the LED production process, and demonstrates that the system simulation technology is an effective method for the LED production process; Second, based on the system simulation theory, the general strategy and procedures for the simulation techniques are analyzed in the production process. Finally, on the basis of analysis of production process, using the...
Nowadays, enterprises survive in a competitive environment. Logistics is looked as “the third profit source” which has big potential in reducing the cost of operations. Especially inventory and transportation occupy a considerable proportion in logistics cost. So reduce the cost becomes the key to reduce it. However, China's enterprises consider how to reduce transport cost or inventory cost only,...
Along with the environment worsening, more and more enterprises intend to recycle and remanufacture the products. On the foundation of market segmentation, we used two periods longitudinal difference model to analyze the manufacturer's optimal price engineering management in the monopolistic market. Finally, the paper proposed some management suggestions for the manufacturer.
Weights is used to measure the relative importance of multiple attributes or objectives, which influences the evaluation or decision result to a great degree. Thus weight sensitivity analysis is an important work in decision-making. An analysis method based on comparison of inclined angles of vectors has been proposed in order to solve the sensitivity of a multiattribute evaluation with isotonicity...
