To effectively reuse existing NC machining process of similar part and feature, an effective data mining approach of existing CAM models in machining process data is proposed. First, a machining feature based multilevel structured CAM model is proposed to reveal the relations between machining features and machining operations. Then, the structured machining know-how database is automatically generated...
During the product configuration design stage, it is important to find useful knowledge to reduce the dedicated efforts of engineers. To fulfill this task, the quality and interestingness of knowledge plays the decisive part. This paper utilizes Apriori algorithm to mine rules from historical data base. In addition the traditional criterions support and confidence, the criterion interestingness is...
It is very important for enterprises to integrate disparate services and data to implement a business process without altering the client side applications. In this paper, a new framework that disparate services and data are composed dynamically based on ESB is proposed, in which business process is analyzed into multiple work-data flows. Dynamic routing mechanism is applied to map abstract description...
This paper analyses the information collection in different construction project phases and give three primary solvents. The first one is to build the LC information collection standards based on the rough set theory. The second one is to settle the problem that how to arrange the sharing path of LC information by applying the sharing knowledge creation model of knowledge management theory. The third...
