Trust Measurement Model for Industrial Control Ethernet Network

Abstract: The application of fieldbus has been limited due to the high cost of hardware and the difficulty in interfacing with multivendor products. In order to solve these problems, the computer network technology, especially Ethernet, is being adopted by the industrial automation field. The key technical obstacle for Ethernet for industrial applications is that its nondeterministic behavior makes it inadequate for real-time applications, where the frames containing real-time information, such as control command and alarm signal, have to be delivered within a certain time limit. Recently, the development of switched Ethernet shows a very promising prospect for industrial applications due to the elimination of uncertainties in the network operation that leads to the dramatically improved performance. We propose a trust evaluation model for industrial control ethernet network . Our study shows the importance and necessity of applying theoretical analyses to understand the complex characteristics of trusted industrial control ethernet networks.

Hopf Bifurcation of a Delayed Ecoepidemic Model with Ratio-Dependent Transmission Rate

Abstract: A delayed ecoepidemic model with ratio-dependent transmission rate has been proposed in this paper. Effects of the time delay due to the gestation of the predator are the main focus of our work. Sufficient conditions for local stability and existence of a Hopf bifurcation of the model are derived by regarding the time delay as the bifurcation parameter. Furthermore, properties of the Hopf bifurcation are investigated by using the normal form theory and the center manifold theorem. Finally, numerical simulations are carried out in order to validate our obtained theoretical results.

A Study on the Evaluation of the Competitiveness of Producer Services by Region in China

Abstract: Through the exploration on the theory of competitiveness,this paper tries to seek a model to evaluate the competitiveness of producer services.It selects various regions in China as the basic unit for the appraisal from macroscopic angle,and further classifies the indicators in producer services from different angles and draws out appraisal indicator system combining the practice of producer services home and broad,based on which the paper explores the efficient evaluation model for producer services in different regions by using Super Efficiency DEA model

A New ISBM-DEA Model on Environmental Efficiency Measurement and Its Numerical Examples

Abstract: Production process of desirable outputs often produces by-products,which have harmful effects on the environmentHowever,traditional DEA models cannot measure efficiency evaluation of these undesirable outputsThis paper proposes an improved DEA-SBM model,named ISBM-DEA,and constructs an illustration to compare it with slacks-based measured DEA modelThe results show that computing conclusions of the new model are highly related to the efficiency assessment of DEA-SBM model,and that it focuses on the effects of undesirable outputs on production efficiency than the latter,which suggests this new model has more extensive value of application

Permanence and Hopf bifurcation of a delayed eco-epidemic model with Leslie–Gower Holling type III functional response

Abstract: This paper is concerned with a delayed eco-epidemic model with a Leslie–Gower Holling type III functional response. The main results are given in terms of permanence and Hopf bifurcation. First of ...
