Evaluation System of Products Design Oriented to KBE

To integrate product design,collaborative evaluation and knowledge management into evaluation system of products design,knowledge based engineering(KBE) was introduced into the design process of the system.The system structure was constructed based on J2EE technology.The model was established by object-oriented method,which integrated the evaluation index system,knowledge BOM and various BOM in product lifecycle.Its data relationships were described by class diagram of UML.The adaptive algorithm model of system evaluation was presented.On this basis,the design evaluation system based on KBE was developed.The running mode of the system was described and its feasibility and practicality were verified by examples.
