Cooperative quality planning system for multi-layer development environment of complex products

To meet the mixture operation model of hierarchical collaboration and peer-to-peer collaboration of quality planning in complex production manufacturing systems, a cooperative quality planning process model was constructed based on a three-tier structure and a cricoid-dendriform process topology. By means of OOP and AOP, the processes and aspects of quality planning were abstracted and encapsulated into an integrated architecture, based on which a quality planning system with high concentration, lax coupling and good process flexibility was designed and realized with the components and middlewares on J2EE platform.
