Based on the environment of four-legged robot soccer competition,this paper presents a new complete distributed multi-agent planning approach,including communication control,path planning and dynamic role assignment.

The mechanism of dynamic role assignment is often required to be supported in many systems developed by using the technology of multi-agent system.

Based on world models of RoboCup legged- robot group soccer competition,this paper mainly discusses about dynamic role assignment and coordination of multi- agent system by the way of image- processing and wireless communication.

Combining with RBAC model,a graded roles based access control model is put forward.

To support recursion mechanisms in software architecture specification,it identifies the concepts of composite connector and dynamic role,and illustrates how it can be used to create dynamic extension of structure.

Based on careful research, a project of user management is designed, which can implements dynamic role management, dynamic authorization management, and have a flexible authorization way.

Application of tunnel monitoring in surrounding rock mass dynamic classification;

A quantitative assessment method for surrounding rock dynamic classification is introduced in order to assure stability in the surrounding rock and the supporting structures during construction and operation.
