The current study state of computer aided 3D tolerance design and several representation models and design methods are summarized and the prospects for development of 3D tolerance design are also put forward.

For better understanding of dynamic co-competition relationship in supply chain network,a multi-layer dynamic co-competition relationship network is presented,followed with a representation model that characterizes the co-competition relationship in the network.

In this paper,a new representation model of design for high level synthesis based on petri net is developed.

We introduce a new type of model representation,the normal interpolation displaced surfaces(NIDS),which decomposes a geometric model into a simple domain mesh and a scalar-valued displacement field over it.

This paper pointed out the problems in the model representation and management during the development of simulation software for the refrigeration and air-conditioning.

This paper proposes a DSS model of representation method called model object -oriented representation method on the basis of studying object oriented model representation method and objectoriented concept, model is also a object, and one to one correspondence.

WSDL presentation model and implementation method;

This paper describes a new kind of presentation model, interface template-based presentation model.
