摊铺机产品全生命周期过程知识重用系统开发研究

Paver belongs to complex mechatronic product, which produces a lot of process knowledge and the knowledge lost will lead to repeated business designs in the whole lifecycle process. In order to use the process knowledge better, the current status of paver’s knowledge and the existing problems in the whole lifecycle were analyzed and concluded. The paver’s whole life cycle process knowledge were studied; exploited and integrated to different types. The ontology_based modeling was used to organize knowledge reasonably and to express knowledge hierarchically with the whole lifecycle main line. The paver’s whole life cycle process knowledge reuse system was developed to improve the efficiency of process knowledge application by approving knowledge definition and variety retrieves, sharing and reusing the process knowledge for different users in paver’s whole lifecycle process.
