Abstract: Water resources reasonable disposition is a measure to solve water shortage problem, cannot still meet the requirement of practice for the knowledge of complex water resources system and the method of describing and other theoretical research. The Yellow River has faced the dry-up of the Yellow River. A Synthetic Decision Support System (SDSS) for water resources dispatch and allocation, based on a new route and method to water resources dispatch and allocation derision-making was developed in order to gain a better understanding of the water resources dispatch and allocation. The paper completes the design of the main structure and functions of the system, and introduces the key techniques of implementing the system, through the analysis of application subject and information integration manner of the system, topological relationship between the water conservancy project entities in various river basins is established using the thought of graphic-topology and tree-topology. Adopting the data warehouse technique, the integration method of facing the decision subject, separation method of the user interface and application program, the method of water resources dispatch and allocation service model based on topological relationship, is established. The model is integrated with the scenario experiences and knowledge about the water resources dispatch and allocation accumulated by the experts and developers. The system has been put into application successfully, and satisfied effects are obtained, therefore it is worthy to be improved and popularized and has the great directive significance and applied value in optimum operation regulation and uniform management of water resources.

Abstract: Currently, many universities have set up their own system for providing employment information service, problems that following the independently operating and maintaining modes are: on the one hand, employers have to register a number of university employment information system to obtain information on a number of graduates; on the other hand, graduates also need to browse a number of university employment information site to get more information on business recruitment, which severely reduces the transparency and efficiency of information data queries. To solve the above problems, this paper propose the university employment information integration model on the basis of distributed storage and computing technology, which realizes the integration of multiple heterogeneous employment information database.

Abstract: The production of rolling steel is a complicated process which includes management of production operations and production process. The former includes costs accounting, procurement plan of raw materials and auxiliary materials and quality control. The latter includes devices, technology and production rhythm of iron making, steel making, casting and rolling. Nowadays, the departments of these two have adopted the computer managing system to improve the efficiency of management. But the concept of collective design of CIMS is not considered thus the computer control system and operations management computer system are isolated. Furthermore, resources are not shared and information is not integrated among the systems thus enterprise competitiveness decreases. This paper designs the rolling steel computer aided manufacturing system based on internet and introduces the three levels system structure of CIMS technology strategy as well as the key technology. This study is of great significance not only in the integration of rolling steel production systems and the sharing information, but also in upgrading the steel enterprises, reducing costs and increasing enterprise competitiveness.

Abstract: Workshop is gathered place and exchange centre of product manufacturing process information (PMPI), which is divided by enterprise heterogeneous systems. This led to the integration and sharing difficulty of PMPI and constrains the information system application in workshop, like MES. To solve this problem an information integration method based on semantic BOM was proposed. Firstly, a global ontology model USBOM of PMPI was constructed which given the unified semantic description of PMPI. Based on USBOM a PMPI integration framework was proposed. Finally, a workshop product manufacturing monitoring system was used as an example to verify the feasibility of this approach.

Abstract: Changes in the development of computing technology and calculation model of a profound impact on the development of human society, the popularity of networks and portable devices today and in the future, desktop computing mode has not been able to adapt to the changes in the development of the computer man-machine relationship changes and user computer method. Pervasive computing is in this context is proposed. The new model emphasizes the computer into people's daily life and working environment, to form a "at any time, everywhere and invisible" computing environment. In such a computing environment, user can calculate the services and information resources through the handheld, wearable devices used or other conventional, unconventional computing devices without obstacles. The innovation from the desktop computing to ubiquitous computing can be seen, human-computer interaction is an important index for pervasive computing.
