    This paper takes the evaluation of overall economic benefit by an example and proposes a simple additive weighting method for time-series multiindices decision making. The method can automatically determine the weight coefficients among the multiindices and the years respectively and it also can obtain the objective evaluation results and conclusions.

    The land-use inforrnation system (LUIS) is a special geographical information system developed under the support of the geographical information system (GIS). It effectively combines the quantitative analysis with space analysis, mixes the feature of the land-use data and figure description, achieves the mutual transfer of the data and figure: and provides some effective methods for the quantitative research and space analysis. The targets, methods and procedures of the overall design of LUIS and its structure function and characteristic are presented in this paper. It provides the guide and references for developing the special GIS suitable for the demand of land-use management. View full abstract»

    In order to testify and examine the ability and correctness of an expert system for diagnosing the faults in the electrical power system of a certain kind of satellite, the authors have developed a simulated testbed according to the operational principle of the electrical power system. This paper takes the solar battery array as an instance introduce the designing principle of its hardware circuits, and presents the methods to design the interface and the software program of the single-chip microprocessor system. The software scheme of the upper computer is introduced at the end of this paper. It has been proved that this simulated system could effectively achieve the complete functions coupled with the simple design by using of various mature techniques in the fields of electronic circuits, single-chip microprocessor and numerical emulation.

    At first, the radar target scattering centers model and MUSIC algorithm are analyzed in this paper. How to efficiently set the parameters of the MUSIC algorithms is given by a great deal of simulated radar data in experiments. After that, according to measured data from two kinds of plane targets on fully polarized and high range resolution radar system, the author mainly investigated particular utilization of MUSIC algorithm in radar imaging. Ana two-dimensional radar images are generated for two targets measured in compact range. In the end. a conclusion is drew about the relation of radar target scattering properties and imaging results. View full abstract»

    This paper presents a hierarchical dynamic routing protocol (HDRP) based on the discrete dynamic programming principle. The proposed protocol can adapt to the dynamic and large computer networks (DLCN) with clustering topology. The procedures for realizing routing update and decision are presented in this paper. The proof of correctness and complexity analysis of the protocol are also made. The performance measures of the HDRP including throughput and average message delay are evaluated by using of simulation. The study shows that the HDRP provides a new available approach to the routing decision for DLCN or high speed networks with clustering topology. View full abstract»

  • An adaptive identification and control scheme using radial basis function networks

    In this paper adapt ive identification and control of non linear dynamical systems are investigated using radial basis function networ ks (RBF). Firstly, a novel approach to train the RBF is introduced. which employs an adaptive fuzzy' generalized learning vector quantization (AFGLVQ) technique and recursive least squares aigorit hm with variable forgetting factor (VRLS). The AFGLVQ adjusts the centers of the RBF while VRLS updates the couneccion weights of the network. The identification algor ithrn has the properties of rapid convergence and pF.-rsistent adaptability that make it suitable for real-tune control. Secondly, on the basis of the one-step ahead REF predictor. the control law is optimized iteratively through a numerical stable Davidon's least squares-based (SDLS) minimization approach. Four nonlinear examples are simulated to demonstrate the effectiveness of the identification and control algorithms. View full abstract»

    A successful simulation still requires the user to have good simulation knowledge and well developed modeling skills despite a large number of simulation software products available to users. This paper presents the design principles and implementation of a layered modeling system known as General-Purpose user-defined Modeling System (GPMS) which provides the user with multiple accesses to build a simulation model at three different levels of knowledge and skills. It does this by purpose-designed GPMS simulation language, which is briefly described in this paper. View full abstract»

    On the basis of sensitivity analysis, an algorithm presented in this paper does a multi-dimensional heuristic search for the optimal solution of complex systems in the feasible intervals of components reliability. Compared with some existing methods: the algorithm both has heuristic speciality that it is modest and easy to implement, and obtains the optimal solution as exact methods do. View full abstract»
