  1. Supply Chain Integration En model for samarbejde i forsyningskæden

  2. Agenda • Anders: • Problem and hypothesis • REA exchanges and types • Ali • Enterprise Integration • Stine • Demo

  3. Supply Chain Complexity • Problems: • Lack of visibility between tiers. No responsiveness. • Tiers have different conceptual schemes and systems that are difficult to integrate. • Trust, security etc…

  4. Solution: REA? • The Resource-Event-Agent model (McCarthy) • Idea: Manage the complexity of the supply chain domain by repeated use of a simple template. • Hypothesis: REA can serve as a model for VMI, CPFR and supply chain integration in general. • The 3 REA exchanges

  5. Transfer • Introduced by McCarthy 1982 • Concerned with the transfer of rights such as ownership, custody, insurance issues etc.. • Independent of perspective so both companies are equally part of the model. (Bidirectionality)

  6. Transformation • Introduced by McCarthy & Geerts 2000 • Concerned with the transformation of features. • Problem: Ownership and custody can not be ignored in transformations due to the ontological nature of a conversion.

  7. Transport • Introduced by us 2005 ;) • Concerned with the flow of resources through different tiers in the supply chain. Also concerned with custody of resources. • Requires an extension of REA: Location

  8. Classification scheme for events • We have introduced a classification scheme to describe the different types of REA-events and –commitments based on the properties that they alter.

  9. Our REA metamodel • New entity: Location • New relations: Capacity, consists, contains, request • Relations between entities are generally many-to-many

  10. Further REA issues • Goods in transit? Can a location always be determined for a ressource? • New event types? (”weak” transfer, maintenance etc….) • Business rules as type images (policies) or logical rules? • Alternative SCM models? (SCOR, ebXML, RosettaNet, proprietary models)

  11. Architecture

  12. Overview • Problems: - Supply Chain interoperability - Converging the conceptual understanding • Providing a common standard to adhere to • Semantic integreation vs. Syntactic integration

  13. Conceptual architecture I • Problems • ”Integration spaghetti” • Small companies are left out • High transactionspecific costs • Non-flexible supply-chain • No ”competitive edge” • ”Island of information”

  14. Conceptual architecture II • Solution • Hub’n’spoke architecture • No maintenance overhead as before • Using the REA-model as the hub • Provide a common and easy to understand concept by focusing on economic primitives • Achive competitive edge

  15. Information requirements Data requirements for salesorder (Agreement & Commitment) 17 elements XML representation of an salesorder from Navision 200+ elements

  16. Standardization • Need for a explicit schema definition • Mismatch between need for a common standard and interest for tight coupling • Non-proprietary standard • Standardization comitees jointly agreeing on a common standard • ebXML and CPFR?

  17. Further integration issues? • Testing integration between different ERP-systems • Providing a framework for EAI tools to achive semantic integration • Alternatives?
