To realize dynamic generation of the access control policies and improve the dynamic adaptability of authorization verification for requester in grid,the automatic composition scheme for access control policy set in grid was put forward.

The automatic composition of fault polygon based on horizontal slice of horizontal coherent volume has been become mature day by day, and his precision depends on the quality of coherent volume processing.

Modeling and analysis of cluster tool with revisiting in semiconductor manufacturing;

It is developed to model the cluster tools in semiconductor manufacturing.

With wafer residency time constraints in cluster tools for semiconductor fabrication,feasibility of schedule and control can not be checked analytically.

Centralized automatic service composition and so called non-trivial service discovery can retrieve compositions of services for a given request that contains particular inputs and outputs, and are now popular research topics in the area of service computing.

This paper presents detailed design and implementation of a fast graphical process modeling tool based on automatic service composition,which can generate executable WS-BPEL document through stepwise query of service composition and flexible assembling of process segments,.

Cluster tools are the critical equipment for semiconductor manufacture,and usually,the bottleneck equipment.

The manufacture process involves the participation of over hundred procedures and many key equipment, which includes so-called cluster tools.
