In the project development process, the various subsystems, the whole system and subsystems, subsystems and the external environment are the existence of a complex between the transmission and exchange of information, its transmission and exchange of research and development progress and costs

7、 are very large the impact on overall system integration and control are concerned, cooperative control interface is their main management issues through effective coordination of interface control, R & D activities to promote inter-organization synchronization is to ensure that an important mea

8、ns to achieve the development goals one. A large R & D projects interface elements R & D projects constitute a large multi-dimensional network interface within the system interface is the communication between heterogeneous organization and delivery, the relationship between organizational i

9、nteraction region. R & D interface can be divided into three forms. 1.1 Process Interface Also known as process interface, usually refers to R & D projects from the demonstration project start to completion of various stages throughout the development cycle with the interface between. Guobin

10、 Deng interface of research and development process is divided into R & D / R & D interface, research and development interface and design, manufacturing engineering interface interface with the time course of a larger relationship. As the project progressed, technology, and products gradual

11、ly from abstract to concrete. Different R & D projects, the process is different, large research projects, often using phase - gate system development, that is the end of each stage, the next before the start of a stage, the need for periodic review, to test the initial results are pre-configure

12、d to meet the needs of the next stage of development conditions are in place to make the decision to continue or give up. In this way the continuous development activities artificially broken down into discrete stages. 1.2 Task interface Task interface is due to be developed by the technical charact

Conducting research and development, the task of showing elements of the serial, parallel, independent of other relatio

14、ns (see Figure 2) and because R & D tasks relevant to the needs of customers, and built on continuous innovation and development, based on the task itself has a number of technical innovation, and thus, R & D process developed by the external environment and internal state of the double impa

15、ct, resulting in task interface in the initial stages of ambiguity and uncertainty. 1.3 Organization Interface R & D projects of various organizations carrier is due to the pursuit of different interests, resulting in co-operation, task and resource allocation in R & D, information transfer

16、and sharing, benefit sharing and other aspects of the interaction between. On the scale of R & D projects different, the composition of the interface relationship of form and function for large-scale development projects, both independent research and development entities, including governments,

17、 intermediary organizations, which in the role of research in different form the complex network organization system, were formed interaction interface shown in Figure 3. Large R & D cooperation projects with the interface of fixity, that R & D projects and participants have been identified

18、that objective, the interdependent relationship between the organization is stable and easy to change while the process and different stages of development, information, technology status, and changing interactions lead to changes in the interface, so the interface R & D project itself is divers

19、e, R & D interaction is a transfer of information between subsystems and interactive process, the evolution of two-way repeated; is the system interaction between each other to synchronize the process. different organizations continued to receive and release information in making system-level ma

20、nagers in technology continue to shape the course of evolution to find a synchronous state of equilibrium, to find the interface between the role of each organizational pattern matching . 2 R & D projects co-chaotic model systems interface Share the free download R & D projects of a complex

21、network system interface control is mainly reflected in: the system administrator through the analysis of the factors that affect the development sub-system development, the various elements of the system to find an optimal way so that all subsystems through collaboration to improve the speed and ef

22、ficiency of R & D According to R & D projects ambiguity and uncertainty characteristics of the core as a non-linear theory of chaos theory to solve large-scale collaborative R & D project control system interface issues and effective tool in a chaotic system to determine the emergence of

23、 the seemingly random movement, is the unity of order and disorder, uncertainty and randomness of unity. aperiodic chaotic system is a dynamic process, and showed a sensitive dependence on initial, revealing the phenomenon might be behind the seemingly random Hidden simple rule, in order to find a l

24、arge class of complex problems generally follow the common laws. R & D organization system with relative independence of each subsystem and their specific functions and operation of the target. For large R & D projects, R & D activities necessary conditions, such as capital, technology,

25、personnel, facilities, policy, and market spread different subsystems for different subsystems have the system of differences within the larger organization. Hence, if the R & D organization into a complex network system abstraction, abstraction of the subsystem into a complex network of nodes,

26、each node then has a different structure, its dynamic behavior are also some differences, such organizations in the delivery information will be a time lag here we choose the node structure of the domestic scholars differ in methods of complex network synchronization and establish collaborative R &a

27、mp; D model of the system interface . Chaos Theory Chaos synchronization and control is through the use of a chaotic system chaotic signals to drive and control another chaotic signal, the final state to converge the two systems, assuming R & D system with m subsystems, each subsystem can be abs

28、tracted into a node, according to chaos theory, research and development project is a chaotic system, each subsystem can also be seen as a chaotic internal structure of different subsystems, so the equation of state of each node is a different structure of the chaotic system, then do not consider Th

32、rative interface has two types of chaos control method. The first is through the appropriate means of control and ways to effectively suppress chaotic behavior, the Lyapunov index decreased thereby eliminating chaos. R & D system brought chaos to large fluctuations, make research and development

33、 results and serious departure from the pre-set target so that the whole R & D system into chaos, the progress of research and development, quality and costs are adversely affected, which should effectively suppress or eliminate chaos. a high level of information overlapping R & D activities to enhance the frequency of interaction, nam
