Research on the Distributed Concurrent and Collaborative Design Platform Architecture Based on SOA

The design and development of the complex product has become a bottleneck restricting the economic development of countries. The concurrent and collaborative design for complex product is a new mode of design and develop based on concurrent engineering and multidisciplinary collaborative design using various fields of Cax. At present, the most advanced collaborative technology in the world is based on the Service-Oriented Architecture (SOA) -an important stratagem of the USA to seize the high ground of international strategy in the 21st century. According to the theory of knowledge flow, concurrent engineering and the optimization theory in the multidisciplinary collaborative design, the paper defines the concept of Distributed Concurrent and Collaborative Design (DCCD). Based on SOA and the distributed intelligent resources environment, this paper first presents a novel DCCD design platform architecture. The architecture based on SOA integrates some large-scale commercial engineering software tools and expert systems so as to quickly accomplish the design and analysis of complex product such as the railway bogies in this paper, which proves the feasibility of the platform architecture. Take the design and development of the railway bogies as an example to demonstrate the application and advancement of the new architecture.
