Towards a Method of Data Management and Consistency Control Based on P2P for Collaborative Product Design

ABSTRACT

In order to meet the requirements of collaboration product design (CPD) across multidisciplinary fields, a method on data management and update consistency control has been proposed based on the peer-to-peer (P2P) network, in the inter-enterprises design process. A kind of design mode of CPD and hierarchical structure of data management are both built. For the management needs of data exchange and information sharing across CPD process, group modeling and dynamic control method associated product design peers are achieved. The causes of data inconsistency are analyzed, and a detection model of data inconsistency is presented as well. Based on the product design constraints satisfaction problems, data update method and consistency control algorithm related to implementing the key update process are also put forward. Based on the open JXTA platform framework, the appropriate system architecture and its functional modules are established and realized for CPD data management. And further follow-up work is also discussed.
