Abstract: With the research and development of software product line and component-based software engineering methodology, it has become key technology how to build component assembly environment and realize heterogeneous component assembly. Thus, a new industrialized product line based integrated software engineering environment (PL-ISEE) model is firstly proposed, and the heterogeneity problems of developed components are analyzed and discussed. For removing components heterogeneity and realizing heterogeneous components assembly, the wrapper wrapping component is studied further. These researches and ideas will play significant role in promoting the formations of component-based software engineering methodology and future industrialized software production technology.

Abstract: t is very important to select critical operations in software reliability testing and software safety testing. In this paper, a framework for selecting critical operations based on Analytic Hierarchy Process (AHP) is proposed. The hierarchies of goals, criteria and alternative programs are introduced separately. A preliminary application is practiced to show the methods application process and demonstrate the feasibility of this method, which can be taken as a reference for critical operations identification in engineering application.

Abstract: 3DR-tree is an index method using the traditional R-tree to index moving objects. Its defect is that a cube generates when an object remains still for a period of time. For those objects that remain still for a long period of time, many strip cubes will generate. MBR will be overlong or overlarge, thus increasing a great deal of overlap and reducing index performance greatly. This paper is to improve the 3DR-tree model to enhance index performance. On the basis of 3DR-tree, this paper will put forward improving historical data index performance of 3DR-tree through node splitting. 3DR-tree is provided with the online data index function by means of tree splitting.

Abstract: Students support service as the characteristics and advantages plays a large role increasingly in distance and open education, while the educators from the distance and open education are practicing their work deeply. As a new mode of education, the Open University has to further make the connotation and function of students support service clear and fixed. In order to benefit the construction of students support service system at the Open University, an analysis is made on its structure of students support service from the perspective of system science to reveal the target, reveal formation of driving force for the dropout rate, the structure and model characteristics of the system at such a university in this paper.

Abstract: Traditionally, enterprises have approached IT modernization and back office process enhancement in silos, by introducing multiple vendors with different technologies, platforms and operating systems, which limits process integrity and leads to disseminated responsibilities. In contrast, the Cloud revolution has made it much easier for enterprises to approach business transformation in a holistic manner, leading to a quantum leap in their business and IT practices and performance. In other words, Cloud-based workflow (which is shorted for cloud workflow) technology is now regarded as a pretty good solution: Cloud workflow helps organizations in process harmonization, optimal organization design and change management offering benefits beyond cost reduction, it enables a complex application instance to be abstractly defined, flexibly configured and auto-operated. This paper introduces shortly the technology of both cloud computing and workflow and then presents the concepts and features of cloud workflow. Meanwhile, the following part discusses the application scenario and the application cases of cloud workflow. Lastly a possible trend of workflow in the future is proposed.

Abstract: This article analyzes the new changes of e-commerces means and business model based on the development of mobile internet. Furthermore, Combined with the influence of the technological progress, such as wireless broadband network, mobile intelligent terminal and cloud computing, this paper puts forward an open system architecture of electronic commerce and its six module systems, and expounds the system design and deployment method in mobile internet environment.

Abstract: Pulse Coupled Neutral Network (PCNN) is a new artificial neural network with biological mechanism, and has been widely applied in many areas such as image processing and so on, but its dynamic characteristics have not been analyzed effectively. In this paper, the dynamic characteristics about pulse period, refractory period and capture period in a simplified PCNN are discussed by mathematical analysis. Simulation results verify the correctness of the analysis conclusions.

Abstract: An SOA-based information integration platform in Chinese tobacco industry enterprise was constituted with SAP XI. SAP XI as the ESB transforms the formats of all data coming from source systems to realize the seamless integration among different systems. The service bus of SAP XI links different systems in enterprises and factories and realizes the seamless integration among multiple business systems of different levels. The application of information integration platform ensures the flexible and controllable information communication among application systems in enterprise at architectural level and solves the problems of information island, data quality and flow integration.

Abstract: With the development of component technology, component granularity plays a very import role on the complexity of component composition. How to assemble the component of big granularity How to make the component in the same domain integrated Application framework brings the new era of software-reused technology. But how to construct application framework to make it higher reuse According to the current research of application framework, the paper gives a hierarchy model; The model divides application framework into several layers. Different application framework in different layer has different solutions and the higher the application framework stands in, the lower the probability of change is.

Abstract: As an important commercial application, E-commerce is widely used with the development of Internet technology. However credit disks block the progress of E-commerce in the non-standard market environment, Analyzing credit management modes such as eBay and Taobao, this paper proposed a new credit calculation formula and construct a credit evaluation framework, in order to improve trading success rate, to avoid commercial fraud, and to contribut information construction of China.
