Deploying networked machining service chain based on semantic Web

摘要

This paper studies on machining services(MS) features and the formation process of networked machining service chain(NMSC) in networked manufacturing environment. Four types of the connection relationship in MSs' composition oriented on machining process are given. A MSs optimization matchmaking model was designed to set semantic similarity and machining service cost constraints as its target function, and a three-tier MS semantic similarity measurement mechanism was poseded, which are composed of the basic matchmaking, the machining rule-constraint matchmaking and service benchmark matchmaking. A two-phase NMSC deployment algorithm was developed.
