摘要:
While design and management of production systems based on digital models brings benefits, the communication of models comes with challenges since models typically r eside in a distributed h eterogeneous IT environment u sing different sy ntax and sem antics. Coping with heterogeneity requires an a ppropriate integration strategy and m ethodology. One m ain paradigm to integrate in formation and consequently IT- sy stems is to deploy standardized information models. In particular, ISO 10303 STEP h a s been endorsed a s a suitable standard to exchange a wide variety of product m anufacturing data. The r epresentation a nd in tegration of pr oduct, process and pr oduction resources information using different STEP application protocols are well cov ered and extensively investigated by many researchers. However, the information r epresentation and integration of logical r elations of m aterial flow such as product r outing, and its integration with factory layout information has been less subject of r esearch focuses. Hence, this thesis first contributes to identif ying, describing and clarif ying information requirements for an integrated representation of material flow log ic and plant layout using the STEP standard. On e the other hand, service-oriented IT-tool integration solutions are increasingly deployed for the data and tool interoperability, especially with the evolution of Open Services for Lifecycle Collaboration (OSLC) whose focus is on the linking of data from h eterogeneous software tools. OSLC focuses on the integration of the most common con cepts across domains. Assuming a loosely coupled distributed architecture of IT- tools and services, OSLC a dopts the Linked Da ta (LD) a pproach to ensure data con sistency across the data sources. Thus the thesis studies the use of OSLC for tool in tegration and has found that it cannot be practiced independently for all types of in tegration in the production engineering domain. Therefore, in practice, there shou
