CINCO Collaborative and interoperable computing Alex Norta, PhD. University of Helsinki Petrozavodsk, May 21 st, 2008 An integrated reference architectures for supporting dynamic business collaboration

Agenda Introduction Electronic B2B collaboration problem − bringing service providers and consumers together Collaboration concepts Example of business process collaboration − in Petri-net The architectures − web-Pilarcos and eSRA Pursuing a merger − through concepts Conclusion

Introduction B2B collaboration with SOC technology − web services, XML, SOAP, UDDI, BPEL, etc. eCommunities: several organizations electronically collaborate with each other. DIBPM: Dynamic Inter-organizational Business Process Management − collaborator organizations are found by searching business process market places − and the sub-processes are integrated with the running process Issues of handling: business-, conceptual-, technological complexity, business relevance of technology, formal rigour eSourcing as an integral concept: harmonizes existing knowledge (used and extended in

eSourcing Concept

Separating Concerns Conceptual level: − processes are mapped to internal level Internal level: − legacy systems, WFMS External level: − stretches across organizational domains − automatic, dynamically forged collaboration − processes projected from conceptual level

Conclusion Service-Oriented Computing mean to automate B2B collaboration Several approaches exist coming from academia (for electronic community formation and business process collaboration) eContracts bind collaboration concepts together Reference architectures exist for collaboration concepts We investigate how they can be merged via exploring shared dynamic collaboration mechanisms. eSourcing an integral concept for DIBPM; used and extended in
