This paper illustrates the feasibility and superiority of the efficiency measurement of logistics enterprises by DEA model. Under the case of CRS and VRS input oriented DEA models, we conduct an analysis on the efficiency measurement of 16 logistics public companies basing on the cross-sectional data of 2008 solved by the multi-stage DEA method. By use of DEAP Version 2.1 we can calculate CRS and...
In this paper, a dynamic pricing model for e-commerce based on data mining is proposed after the comprehensive analysis of data mining technology applications and e-commerce dynamic pricing strategies. The authors introduce this model into the pricing mechanisms of TaoBao, and discuss the application of the model in C2C and B2C modes, which has great reference value for e-commerce enterprise operation.
Radon is the only one gas which produced in the process of mining uranium. It's very harmful to the human body. In this paper, the feed-forward neural network (BP ANN) structural features, data analysis, the learning process and so on are analyzed. We set up radon of Fuzhou Jin-An Uranium Industry Limited Company study and training for the state samples and samples of the forecast, and then establish...
Coal mine safety management is one of the most important basic job, and related with almost all coal production systems. It analyzed characteristics of coal mine data which not only show data volume large, information sources excessively, but also is dynamic, random and fuzzy. It stressed that application of data mining technology to coal mine safety is an important way to improve mine safety work...
Project risk element transmission theory puts forward a new idea of research on project risk management. This paper combined with state transfer diagram, analysed enterprise multi-project management, made concrete exposition on the thought of project chain with different risk element kinds. A tetrahedral structure model of enterprise project chain risk element transmission and controlling mechanism...
On the basis of the deep search and analysis of the relative literature of virtual R&D team, the article summaries a total of 11 key factors which influence the virtual R&D team performance. And the article uses "input - process - output" model (IPO: input-process-output)to build a performance influencing factors model of virtual R&D team, and brings up theoretical assumptions...
Business process's performance determine the whole enterprise's economic profit, researching work on business process's optimization is very useful and meaningful. This thesis point out that manager must take the dynamic environment and multiple objectives into account while optimizing the enterprise's business process. Based on the theory of multiple objective optimizations, AHP, and simulation technology,...
In the research of relationship between enterprise profit and financing choice, the existing literatures mainly focus on the regression analysis using leverage ratio as the proxy of capital structure. This paper asserts that the dual effect of debt-equity financing has been incorporated into leverage ratio; therefore, regression analysis merely on leverage ratio fails to uncover the financing choice...
Study on scientific research capability of national defense university is conducted with a view of analyzing effect elements, in which an evaluation index system and evaluation model of scientific research capability of national defense university is constructed. Scientific research capability of national defense university consists of four aspects, i.e., scientific research input, transformation...
A delayed reaction-diffusion model is established to describe the hepatitis B virus (HBV) infection and control, where the diffusion is confined to a finite domain. According to the practical meaning of the model, the equilibrium solutions of the system are derived and analyzed. Different situations of time delay and diffusion are validated by computer simulations.
This paper established distance education model of knowledge transmitting, which aimed at the spread characteristics of distance education network in general colleges and universities, based on the theory of complex networks. The model simulated and analyzed if it existed that individual who learned by distance education network excluded increasing of knowledge level. In the proposed model, the Cobb-Douglas...
This paper analyzes the stage of maturity that neurofuzzy systems (and soft computing in general) have recently reached and tackles the several reasons why they have not yet reached a widespread acceptance in industrial and agronomic applications, despite the good performance they can offer with a reduced design effort.
Information foraging has gained broad attentions within the cognitive science, computer science and library and information science community in recent years, and its critical ideas have affected these communities a lot. However, few researchers get the basic view of information foraging theory which will blocks this theory's future development. The paper gives a framework for information foraging...
The integrative approach of systems biology promises a better understanding of complex phenotypes such as cardiovascular disease, diabetes or chronic obstructive pulmonary disease (COPD). It aims to interconnect current knowledge with experimental data, in-silico analysis and simulation. To this end the existing knowledge must be semantically integrated in a single environment and dynamically organised...
In this paper, we propose a new diagnostic checking tool for fuzzy rule-based modelling of time series. Through the study of the residuals in the Lagrange multiplier testing framework we devise a hypothesis test which allows us to determine if there is some left autocorrelation in the error series. This is an important step towards a statistically sound modelling strategy for fuzzy rule-based models.
The evaluation for current situation of ecological compensation is significant to strengthen the system of ecological compensation. In the study, the method based on the combination of analytic hierarchy process (AHP) and fuzzy theory is proposed to evaluate ecological compensation. Firstly, evaluation indexes for ecological compensation are described, and the evaluation model of ecological compensation...
Artificial searching swarm algorithm (ASSA) is a new optimization algorithm. This paper presents two type behaviors rules of searching swarm, and discusses the performance of the algorithm based on the different rules. By analyzing the simulation results, an improved ASSA with mutative searching step is proposed. The function simulation tests prove that the improved algorithm implements better performance...
This paper combines the research achievements of scholars at home and abroad to reach a formula of explicit expression knowledge value of employee. Then, using complete information static game model, from the view of cost factors, the knowledge store of employees and motivation factors to do game analysis of the preconditions of knowledge transfer (KT). The various measures to improve the knowledge...
Artificial searching swarm algorithm (ASSA) is a novel optimization algorithm. This paper presents the comparison results on the performance of the ASSA for solving constrained optimization problems. The penalty function method and non-parameter penalty method are applied to a set of constrained problem. The simulation results show that ASSA is an efficient algorithm for constrained optimization problems.
As a new modeling thought, the accurate analytical redundancy model of power plant critical parameters was established by data mining method, which obtained effective information from the large number of real-time operation data. The basic modeling mode, including data preprocessing, mining model, verification model and the strategy from data to analytical redundancy model, was proposed in the paper...
