FRACAS Based Failure Information Management for High-Speed Train

Failure, because of the important role in the product life cycle for improving product design and manufacturing, is becoming important data information and being taken seriously. High-speed trains are complex electromechanical integration systems, and its failure occurred in operation may directly relate to people's life and property safety. FRACAS is a reliability engineering method, which allows the product fault information to follow Discovering, Report, Analysis,Correct andConfirm closed-loop management process, provides data and information to support effectively for improving the reliability of the train. This paper analyzed the fault information management needs of high-speed trains, combines high-speed trains product structure tree and fault model base to generate a high-speed train fault information database, by customizing and developing Relex FRACAS software. Then high-speed trains (CRH3) closed-loop management system is established. High-speed train FRACAS can easily build enterprise information platform for product reliability. Through the establishment of a unified failures database and solutions knowledge base, standardized information transferring and sharing are achieved. The train products faults can be timely reported and corrected. The accumulated data of troubleshooting in the whole process can be used in the failure statistical analysis and reliability prediction, which can effectively avoid major failures and repeated failures.

A Design of IT Enterprise Information Platform in Cloud Environment

This paper seeks to combine the advantages of cloud computing to design an IT enterprise alliance information platform based on cloud computing. In this study, we adopt B/S framework of tree cloud database to store IT enterprise alliance information for this platform, which is used for activity data collection and its subsequent analysis. Further, starting with the demand analysis of IT enterprise alliance information, we investigate the function of the information platform, including information release function, knowledge sharing function and online communication function and so on. At last, we propose and devise an effective IT enterprise alliance information platform utilizing the cloud resource to complete handling business problems between alliance enterprises effectively.

The Enterprise Information System Application Platform Architecture and Key Technologies of the Complete Sets of Electrical Appliances Enterprise

This article analyzes the characteristics of complete sets of electrical appliances enterprise production and the current situation and the demand situation of enterprise information application, points out that the complete sets of electrical appliances enterprise information platform should be based on product data management, including CAX/CAPP/PDM/ERP integrated application platform. In this platform architecture, information integration of product data management is responsible for the management of design and process, generate BOM design and process of BOM, form the basis for ERP data, and ERP is responsible for the order of the original information input, logistics and cash flow. Using the corresponding interface design, PDM and ERP will keep database exchange of information. In the J2EE platform, establish the enterprise PDM and ERP system prototype. In system implementation, the phases of the modular structure, construct the enterprise information platform of the system. As to demonstrate the application, in a relatively short period of time, complete the implementation of a complete set of electric enterprise information system, and achieved remarkable results.

The General J2EE-Based Enterprise Information Platform

A Enterprise Application Integration system named Enterprise Information Platform is designed and implemented in a J2EE environment to ensure data share across any operating system and network. Based on message mechanism, JMS is used to transfer message and XML is chosen to organize the format of communication data which can provide services and application programming interfaces to integrate heterogeneous data. This system has been successfully used in some enterprise, and its generality, openness, multiplexing and extensiveness has also been proved in practice.
