This article mainly discuss the influence factors of the Beijing new airport freight Volume, choice the highest correlation regional economic indexes, check the previous data, verify the feasibility of the model, and the forecast the Beijing new airport freight volume in the future.
With the research on the emergency disposal, we build a new contingency scheme model based on the Petri net. The model can meet the needs of the emergency disposal of large ceremony. With this model, we can realize the automatic scheduling of the contingency scheme, control according to the feedback and help the commander to make the decision. It will make all people and departments work in harmony...
To ensure realization of design quality objectives in manufacturing processes, quality information produced in manufacturing processes should be considered by designers. Integrating manufacturing quality information with design tools is an effective way to utilize such information. Firstly, the demands for manufacturing quality information supporting design are analyzed briefly in this paper. Then,...
An efficient way of searching the CAD models for reusing the design knowledge is proposed in this paper. Three searching interfaces are provided for the consideration of different requirements in the procedure of model design. The text-based searching interface is generally used in conceptual design to find the CAD models based on descriptive information, e.g. functional requirements or application...
With the development of virtual reality technology, simulation of plant growth is a hotspot in virtual reality area. In order to reflect the characteristic features of a particular kind of tree and the influence of environment during the process of simulating tree, this paper proposed an virtual tree model based ondynamic forest growing simulation system environment influence (VTMEI). In addition,...
