Abstract: It is difficult to assess the design of satellite information application chain, but it is very important to do it. In this paper, we try to assess the information flow instead of the whole designed satellite information application chain. For information exchange can reflects the main characters of satellite information application chain. The assessment of the information flow is much easier, and also reflects the design quality of satellite information application chain.

Abstract: A simulation system on information flow is designed to emulate the data communication on the RS-485 bus, the 1553B bus and the Ethernet bus. This simulation system has a high requirement for the extendibility, and it must have an ability to regulate and reconfigure the information flow on the three buses. To deal with the above problems, the simulation system has to be designed as a reconfigurable extendible real-time multi-bus simulation system. In order to meet the real-time requirements for the simulation of the information flow and the universal property for the most systems, this simulation system must be carried out based on a real-time operating systems (VxWorks) and a common hardware platforms. Firstly, this simulation system will have a total emulation and a whole simulation for the information flow, the communication status, the monitor nodes and the control nodes on each of the three buses. Secondly, this simulation system defines an extendible protocol between the simulation sever and the simulation terminals, and strictly plan the information flow among the simulation terminals to achieve the design requirements of the actual system. And then the simulation system has to own a reconfigure software components and a complete database functions of recording and stacking the data.

Abstract: Lacking internal logistics process analysis and design in the logistics park planning has a certain influence on the park construction and post-development. Given this, this paper proposed general design principles of internal logistics processes of the logistics park and whereby internal logistics processes designed with the combination of ideas of IOT to the information flow, which can significantly enhance the overall service level of the logistics park.

Abstract: Project is the lifeblood of construction enterprise, weak management capabilities of project will cause low operation efficiency and resource waste. According to the management characteristics of construction enterprise, the business layer should be in the core of management architecture. It is necessary to strengthen project management by information circulation to eliminate the internal information islands. At the macro level, a closed circulatory management model for construction enterprise based on information platform is constructed. In order to get the effective management control of project at the micro level, the project management control model from information flow perspective is suggested.

Abstract: Integration of computer-aided design (CAD) and computer-aided manufacturing (CAM) have been extensively studied by the people both in academia and industry during the last few decades. Because of fluency of information flow achieved by taking the same data model, advantages brought from integration of CAD and CAM are obvious, such as cost savings and improved efficiency. However, another impediment about information flow still exists between CAM and Computerized Numerical Control (CNC). The data model used in the planning department is quite different to the G codes (ISO 6983) used on the shopfloor. This means that the translation of the data format is inescapable, moreover, any information added or modified by the operator on the shopfloor cannot be fed back to the planning department. a two-directional interface between CAM and CNC. Integration of CAM and CNC based on STEP-NC can be realized seamlessly.

Abstract: A four-stage methodological framework useful to analyze the performance of a product development process, with a focus on the information flow inefficiencies is presented. The formal and informal communication exchange between interacting tasks is captured through the Dependency Structure Matrix (DSM) representation, while the properties of the information flow structure are explored calculating metrics of Social Network Analysis (SNA). Information exchange inefficiency of process tasks is calculated performing Data Envelopment Analysis (DEA).

Abstract: Analyses the demand to information flow control technology in smart distribution grid, points out that IEC 61968 based information exchange bus has defects in information flow control, and proposes a framework that consists of flow direction control, information content control and flow runtime control. Based on principle of active and collaborative control, this paper proposes also detailed designs of flow direction arrangement, adapter identification, flow direction analysis, syntax validation, semantic validation and runtime control which consist of start-stop control, traffic control and priority control. The framework and its control functions provide a flexible, uniform and stable solution to information flow control in smart distribution grid.

Abstract: In order to solve the problem of the desynchronized between entity flow and information flow in space and time, the paper puts forward the intelligent shelf system based on IOT tech. Through the deployment design of the hardware structure and analyzing of intelligent shelf architecture systematically, it realizes entity flow and information flow synchronization in business process, which makes the warehouse management more efficient and visible.

Abstract: E-Kanban management is an effective tool to achieve lean and just-in-time(JIT) production. Based on the analysis of the traditional Kanban and the advantages of E-Kanban, types and function of E-Kanban in construction industry are proposed. The framework of E-Kanban management in steel structure engineering of an international expo center which covers decision layer, business layer and technical support layer is built in this paper. The E-Kanban management system and the models of E-Kanban in steel structure engineering are designed on basis of this framework. The system focuses on function and application of Transmit E-Kanban, produce E-Kanban, temporary E-Kanban and feedback E-Kanban. The research of this paper provides the theory and practice foundation for the application of E-Kanban in construction industry.

Abstract: Green Building and Information Model are the focus and developing tendency in the future. Therefore, the combination of the two will push and accelerate the progress of Chinese Green Construction forward. Thus this paper attempts to introduce the idea of GBIM, which takes information flowing technology as the nucleus, is the compound of data integration of BIM and integral management, is also the integration of information exchange and concordance for the tool software at different phases and in different professions with green construction process and tasks. At last, this information flow technology is applied to information flow model building in the green construction planning and designing.
