This paper studies in a two level supply chain composed of one manufacturer and multiple retailers, how participants cooperate to enhance the chain's value. Assuming the manufacturer produces to orders with only one equipment and retailers face fixed market demands, the paper first analyzes the chaos in the EOQ policy, then proposes a new coordinate model, as is called 'the ideal ordering model' to...
In this paper, an effective scheme is proposed for coding n-node Boolean networks. The scheme can uniquely designate a distinguished integer in the range from 0 to (2n×2n -1) for any a given Boolean network. At the same time, a linearized matrix is obtained for any a given Boolean network. The linearized matrix depends only on the information hidden in the logical table of the given network. By analyzing...
Adaptive control technique is adopted to synchronize two identical non-autonomous systems with unknown parameters in finite time. A virtual unknown parameter is introduced in order to avoid the unknown parameters from appearing in the controllers and parameters update laws. The Duffing equation and a gyrostat system are chosen as the numerical examples to show the validity of the present method.
In this paper, it is to apply genetic programming to explore some new chaotic systems. Based on a tree representation, each function in the state dynamical equation of a chaotic system can be well defined. Thus, through the optimization process governed by genetic programming, it is demonstrated that some new potential forms can be determined, for which chaotic systems are obtained by having tuning...
The paper has made the analysis for the unbalanced international trade at the later stage of the global financial crisis. Through the analysis of the reason for the unbalanced international trade, the paper has argued that the broken symmetric conditions have resulted in the international trade unbalance. Based on it, the paper has made the chaos analysis of the unbalanced international trade at the...
According to chaotic characteristics, a method for studying on chaos by using Poincare sections is proposed. The method can study on sensitivity to parameters and initial conditions for chaotic system. A lot of experiments based on Chua's chaotic circuit have been done. The simulation results demonstrate the effectiveness of this method.
Based on the N-S and Maxwell equation, a mathematical model describing the arc behavior in SF6 circuit breaker (CB) has been deduced. The effect of Lorentz force, turbulent and physical parameters on the characteristic of arc plasma was considered in the model. Using the finite volume method, the distributions of controlling parameters for arc in SF6 circuit breaker, such as viscosity, electric conductivity,...
In this paper, an impulsive reaction-diffusion system is studied. Sufficient conditions are obtained for the global existence of solution for the impulsive system. By considering the equiattractivity property of the impulsive error system, the impulsive synchronization of the reaction-diffusion system is investigated, and the sufficient conditions leading to the equiattractivity property are obtained,...
By using the method of planar dynamical systems, the dynamical behavior of the corresponding traveling wave system to a nonlinear diffusion-convection equation is discussed, and the exact explicit parametric representations of all the traveling wave solutions are obtained.
Chaotic Ant Swarm is a recently new and promising algorithm of Optimization Problem based on the chaotic theory and foraging food processing of ants. This paper proposes a Multi-Objective Optimization version of CAS, named MOCAS, by changing the colony behavior organization. The proposed algorithm also introduced a re-distribution operation that ensures the uniform distribution of final result. We...
This paper proposes a novel spatial domain color digital watermarking scheme based on chaotic maps, and the host image is color RGB image. Using Lorenz map and the Arnold cat map encrypt the watermark signal and the embedding position of the host image each other. The color space of the color host image is first converted from RGB to YCbCr. In order to resist JPEG compression, all three watermark...
Taking an electric spindle equipped with AMB as the research object, this paper have established the non-linear dynamic model of five degrees of freedom for the rotor-AMB system, and carried on the numerical solution using the principle of multi-scale method and combined with the numerical analysis method. Besides, from the nonlinear viewpoint, the dynamic characteristics of rotor-AMB system have...
Cycling chaos, in which orbits of certain coupled iterated maps make periodic excursions between chaotic sets, is proposed as a new encryption approach that combines chaotic behavior with periodic switching of keys. We implement the encryption and decryption of cycling chaos system which is composed by three one-dimensional coupled cells. The internal dynamics of each cell is determined by the Cubic...
