Abstract: This paper discussed production order picking schedule problem in AGV-based FMS. A general formulation of production order picking schedule mode is suggestion with objective of minimizing the order picking time and the number of AGVs. Based on the analysis that the relationship between our problem and the standard VRP, we design a genetic algorithm (GA) to solve the mode. Computational experiment is conducted and excellent computational results comparison with other method indicates that the genetic algorithm proposed in this paper is suitable for production order picking problem.

Abstract: The use of grid manufacturing system, has become the trend of modern manufacturing technology. With reference to the idea of component design for workshop production business, a workflow and multi-agent based Grid of Reconfigurable of Manufacturing Execution System (GRMES) is presented. The configurable workshop production business can be handled, and the MES application system can correspondingly adjust with its change. The KQML is expanded to compensate for its description ability in the Workflow management system. XML is applied to support the data flow in GRMES, format the dispatched tasks and KQML, which can securely and concisely transfer different data among the workflow engines, agents and application on the GRMES. GRMES improves the problems such as adaptability and reconstructivity, which exist in the traditional MES.

Abstract: The fracture splitting (FS) method is a bran-new processing technique in the automobile engine connecting rod manufacturing industry, FS is one of three pivotal working procedures, and press speed is one of the key influence factors of FS process. In order to realize parameters of press speed and pull cylinder working pressure, dynamic simulation of hydraulic system has been carried out. Simulation results indicated that press speed of pull cylinder was about 130mm/s, which was between 120mm/s and 150mm/s that was not only good for controlling FS quality, but also not leading irrational design of hydraulic system. The working pressure of pull cylinder was between 10MPa and 14MPa, which was suitable for FS processing. The hydraulic system of FS machine can satisfy the basic requirements of connecting rods FS process. This paper has provided reliable theoretic basis for the design of FS machine for connecting rods.

Abstract: With the transformation of the understandings from technology-oriented information management mode to competition-oriented information management mode, SIS emerges as the times require. SIS is the outcome of the integration of modern information technology and business management concept according to the demands of competition and development. This paper has discussed the creation, background, structure, function and planning of SIS.

Abstract: The Model Driver Framework was designed to facilitate analyses of complex systems. It completely divorces the model execution process from the model itself. By doing so it frees the modeler to develop a library of standard modeling processes such as design of experiments, optimizers, parameter studies, and sensitivity studies which can then be applied to any of their available models. The framework accomplishes this by means of a well defined API and object structure. Both the API and object structure are presented here with enough detail to implement the framework in any object-oriented language or modeling tool.

Abstract: It is introduced the new linkage-cam combination mechanism that has been designed and analyzed performance in the paper. Based on it and gear one teeth theory, the new type linkage-cam reducer has been successfully developed and have done structural design, model trial and industry testing ,the result is shown that the linkage-cam reducer have big drive ratio, enough high load capacity, high efficiency and so on, which provide a new type reducer for domestic reducer. Based on the operating principle and structure of linkage-cam reducers, series parameters are worked out and finally determined 9 types and 10 drive ratios. The specify type linkage-cam reducers are created 3D model，which makes series design slight simply, moreover providing fundamental basis for their application and popularization.

Abstract: The method of enterprise information integration of electrical power base on the Service-Oriented Architecture (SOA) is introduced. Through the application example of an electric enterprise information integration based on the Service-Oriented Architecture, the analysis design and implement of information integration is discussed.

Abstract: Clustering analysis is an important research area of Data Mining; it is a mathematical method to classification in terms of certain demand and rules. In this paper, the authors have applied fuzzy theory to the clustering analysis, and introduce data mining technology to the electrolytic control, and Carry on the excavation analysis of a variety of data produced by the control system, and then analyze the clustering result. Thus it achieves Electrolyzer’s condition diagnosis and production decision-making functions, and then achieves standardization of electrolyzer operation.

Abstract: In this paper, we present a representative theory for finite fields called the Lagrange Representation recently initialized by Bajard et al. Our contribution is of introducing a new method for computing the leading coefficient of an arbitrary field polynomial, and establishing a field modular multiplication algorithm. Some concrete examples are given in order to emphasize illustration of the method.

Abstract: The question to choose a grain supplement emergency path is uncertain. By using uncertain methods, integration of experts can be done. Base on the uncertain theory, we build the model of choosing a path with minimum risk in the process of grain emergency transportation and the algorithm. Firstly, estimate every path in the net to get the unascertained numbers of experts. Then, the unascertained number of experts with the uncertain operate rule is computed. Thirdly, the expectation and reliability of its unascertained number can be gotten. At last, get the minimum risk path by operate the expectation and the experiential value. This model has certain rationality and validity by data test.
