Based on the application of active networks in congestion control, this paper introduces the traditional congestion control policy and analyses their principles and feasibilities. Active networks congestion control policy introduces the active detection and the passive notification mechanism, the random early detect (RED) queue management and the load balance technology based on the traditional congestion...
Due to the rapid development of information technologies mobile payment is crucial for, but not limited to UC scenarios. This paper introduce four kinds of main mobile payment model and comparative analysis the models. It also describes the existing deficiencies of the models and gives the corresponding countermeasures.
The neural network risk analysis model for the project with fragmentary information is proposed by this paper. With plenty of adjustable parameters, the neural network risk analysis model is more flexible and shows more advantage in evaluating fragmentary information. Simulated by neurons, risk items are transferred within neural network and finally the evaluation result is obtained.
NC-OFDM is OFDM-based spectrum pooling technique and also a transmission mode of cognitive radio. The paper models and analyzes NC-OFDM stochastic process, then designs stochastic comb-pilot pattern and analyzes its characteristics in detail. At the end of the paper simulation results prove the feasibilities of the stochastic comb-pilot strategies in NC-OFDM system.
In IEEE 802.16e system, mobile station (MS) is usually powered by battery. To save the limited power, IEEE 802.16e standard specifies sleep mode operation for power management. There are two significant performance metrics in sleep mode operation, one is energy consumption, the other is waiting delay. Our research is to shorten energy consumption and waiting delay. In this paper, a hybrid algorithm...
This paper considers a optimal dividend problem for a company whose asset follows a Markov-modulated risk model. In the two-state Markov-switching setting, explicit formulas for the expected discounted dividends and the expected time of ruin are derived when the dividend strategy follows a constant barrier dividend strategy.
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...
This paper analyzes the distinctions and connections among industrial cluster, industrial agglomeration and enterprise cluster, and indicates that they are three stages in the process of industrial cluster formation and evolution. Then the thesis offers a three-stage model and an empirical analysis of industrial cluster in Dalian accordingly.
The synergetic innovation of manufacturing enterprise is based on the competition and collaboration. The behavior process model of synergetic innovation is set up and three important parts are discussed: strategy, organization, and mechanism. Two kinds of co-existence models of synergetic innovation model are analyzed. The co-existence model of equal strength explains that the core enterprise plays...
In order to promote knowledge sharing and knowledge reuse of scientific research achievements, this paper proposes a knowledge network model which acts as a direct access to the knowledge existed in the achievements. As knowledge network can be treated with a kind of complex networks, this paper then optimizes the primitive knowledge network model by analyzing its network characteristics. Figures...
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...
TMT (Top Management Team, TMT) refers to the relatively small team of top executives with overall responsibility for the organization The group effectiveness of TMT is becoming more and more important while facing the complicated and fast changeable management environment. This paper gave analysis and summarization of the researches on TMT, and then presented a multi-agent model to study the relationship...
It is important issue for the study of method of the project risk assessment. The quantitative method is used to resolve construction project risk assessment in this paper. Firstly, the study of project risk management and risk assessment is made a review. Secondly, the project risk management systematic framework is constructed, which include five purchases: risk identification, risk assessment,...
To solve the problem that the forecast accuracy is too weak when adopting former monitoring models to deal with dam monitoring data, a new deformation monitoring model has been put forward based on hierarchical diagonal neural network that can approximate any nonlinear function. The model takes water pressure, temperature and age factors as the input and dam deformation as the output. And then the...
Based on matrix analysis method, this paper analyzes the strengths and weaknesses within and without Hebei Province, the opportunities and threats of Hebei Province in the coordinated development of region. It puts forward eight feasible strategic projects. And the paper adopted quantitative methods, selected some strategic projects fitting in with the development of Hebei Province. In this process,...
Industrial international competitiveness is a hot research issue of the current economic field. Many scholars at home and abroad make a great deal of research on it, but a broad overview of its theory and analysis model is not common. This paper firstly analyzed the different explanation on the industrial international competitiveness by the absolute cost advantage theory, the relative competitive...
Human resource flexible management can be adapted to the trend of agiler and more flexible manufacturing. However, there are differences for various manufacturing enterprises to implement flexible management. The paper designs an evaluation indicator system and analytical model according to four flexible aspects (i.e., functional flexibility, work flexibility, compensation flexibility, and structural...
Bayesian method is a significant methodology in decision-making process, according to the new situation and characteristic of the current research and development, the drawbacks of conventional statistic evaluation method can be avoided while Bayesian analysis is applied in the decision-making process. Moreover, as the information collected from the simulation experiment is utilized amply, and the...
The analysis model of industrial international competitiveness is a basic theory and analytical framework to guide the research on the industrial international competitiveness. This paper discussed the relationship and difference between industrial international competitiveness, product competitiveness, enterprise competitiveness, and national competitiveness. Moreover, this paper brought forward...
Rare event management is one important research direction in management science currently. Emergency material transport process is one important issue when rare event happens. How to model the emergency material transport process, to evaluate the performance measures of the process are one of the most important issues in real- world. We use generalized stochastic petri net (GSPN) to model the emergency...
