In material mechanics, when a beam of internal uniform structure bends under the horizontal extrusion, the distribution of stress in the beam differs obviously, there is a surface of no strain, which is called the neutral plane,neither extended nor shortened, however, the upper of which extends because of tension, while the lower of which shortens because of compression[5].

Haeckel pointed out that “Ecology is the science of the relationship of organisms with each other and with their environments.”
The comparatively influential concept of Ecosystem was supported by Eugene·Audemn, who regarded the Ecosystem as all the ecological community together with it environment, functioning as a unit where certain nutrition fabric and material cycle were formed inside by energy flow[1].

In the model, any completion of a task are dependent on the completion of all a task, and tasks can be unlimited levels of decomposition down, so to meet the various needs. 2) Process model: The purpose of the process model is to analyze and design business processes from a functional perspective. 3) Resource configuration: Resources configuration used to represent such business processes involved of various resources in the implementation process, such as equipment resources, tools, resources, material resources. 4) Organization model: The organizational model is the model used to define the human form of organization, which describes the people, departments as well as the relationship between people and departments involved in the project.
Shown in Fig. 6: Fig. 6 Retrospective of the organization of information Conclusion Workflow-based aircraft product data traceability technology solved the transmission of information between the design department and manufacturing department must rely on the status of the paper material, effectively improved the speed of the aircraft to the development of information transmission, to ensure the consistency and dynamic of information, reduced costs, shorten the life of the aircraft development cycle, but also can be traced the aircraft development lifecycle data.
