Abstract: This paper deals with the effective design and implementation aspects of distributed business information systems. After a short introduction to the state of the art, it proposes a study on a payment protocol design, which is based on the composition method.

Abstract: In the manufacturing industry of the Coal-Electricity integration, due to the high-level of coal price, thermal power enterprises are in severe situations currently. This paper analyzes the relationship between the coal manufacturing industry and power manufacturing industry in China, and points out that coal-electricity integration is one important way to develop China's power industry. It also makes a comprehensive analysis and evaluation on the advantages and disadvantages of coal-electricity integration manufacturing industry. Thermal power enterprises should estimate the coming risk in the process of coal-electricity integration, and spare their efforts to improve the adaptability, thereby enhances the comprehensive ability to resist risks.

Abstract: Class-based stereo warehouse storage policy distributes products among a number of classes and for each class it reserves a region within the storage area. In this paper, a genetic algorithm method of using the intersectant operation of chromosome repair and mutation operation of two-way movement detection is developed to solve an integer programming model for storage assignment. Computational experience on randomly generated data sets and an industrial case shows that improved genetic algorithm gives superior results than the genetic algorithm without improving for storage location assignment with ordering restriction.

Abstract: The expression of virtual geographic environment is based on the surface modeling, such as three-dimensional terrain modeling and rendering most of which are based on the polygon grid and 2D textured. In the expression of extreme terrain, such as caves, cliffs, canyons it seems powerless. However, the voxel-based terrain modeling has been more useful than polygon modeling expression in the field of real-time terrain deformation, extreme terrain simulation and geographic process expression. Furthermore, virtual geographic environment based on the traditional surface model is difficult to realistically simulate the real world which is volumetric. This paper analyzes the trends of the geographical environment representation, and discusses the typical voxel-based applications in natural phenomena simulation, terrain modeling and spatial process analysis. It provides the references for the integrative representation of the unified voxel and surface model, and for the construction of virtual geographic environment unified platform.

Abstract: In this paper a solution of soft real time scheduling in manufacturing systems is presented. The basic requirements of scheduling as a real time system are discussed. The proposed rescheduling method uses predictive-reactive strategy and multi thread searching approach with rule-based heuristics, meta-heuristics and random modules.

Abstract: The necessity of PDF417 barcode technology in application of aviation spare parts management is described. And through the careful requirement analysis and discussion the feasibility of automatic identification system for aviation spare parts management information barcode is also discussed. In addition, the development and design ideas of the production system and application system on PDF417 barcode are introduced. It can be included from the research that, the technology can effectively overcome the drawbacks such as error easiness, low efficiency that the manual input bring on in supply and management for aviation spare parts, and can realize the automatic identification, input and monitoring for aviation spare parts information.

Abstract: This paper deals with mechanisms designed to security of computer networks and their use in practice. In the first part of the work we reflect on the necessity of the operation of these mechanisms. The second part follows with theoretical description of the technology used according to various criteria. The final part of the work deals with the design of the security system and an example configuration of active network element.

Abstract: In view of the disadvantages of traditional enterprise security management and the advantages of animation system such as vivid imagined and well-accepted，the author in this article studies enterprise security management model based on the system，including the following five aspects：Representation of the safe production scene in enterprise；Simulation of the accident process；Simulation of the emergency rescue；Education and training programs of safety knowledge and the simulation of product safe performance. Animation technology will bring a new thought to enterprise security management. It will not only help enterprises to solve many security problems，but also take great significant changes in safety production and safety education.

Abstract: Enterprise service is transforming from traditional physical computing nodes to virtual machines which provides better isolation and more effective use of computing ability of the hardware. However, the widely deployment of virtual machines also increase the pressure of storage significantly with the fact that each must has at list one multi-gigabytes image file to store. To address the high pressure of storage from virtual machine images, we developed a user level inline deduplication file system with Content Addressable Storage (CAS). We use the open-source framework FUSE to encapsulate the deduplication process so as to achieve portability and flexibility. Compared to an ordinary file system without deduplication, we show that our file system can save at least 30% of space of single VM image and even more of multiple VM images while achieving considerable run time performance.

Abstract: This article proposes the major issues of our country’s current green building development, that is lacking the social basis, weak policy implementation, the dependence on high technology, complex system structure, shifting of the responsibility of resources crisis, or being unworthy of the name; high economic cost, lacking of market acceptance; ignoring the people-oriented, the lack of characteristic content. Only properly having solved these issues, can we eliminate obstacles to the development of green building.
