STASIS Open WorkshopPage 2 Topic 1 – Introduction Topic 4 – Conclusion and Outlook Topic 2 – The Modelling Challenge in BREIN Topic 3 – Addressing the BREIN Modelling Challenge

STASIS Open WorkshopPage 3 Business objective driven REliable and Intelligent grids for real busiNess BREIN will realise the flexible, intelligent Virtual Organisation support to significantly reduce the complexity of modern day business-to-business collaborations BREIN Mission Statement 2 Scenarios Airport Management SzenarioAirport Management Szenario Virtual Engineering SzenarioVirtual Engineering Szenario

STASIS Open WorkshopPage 4 Introduction The aim of BREIN is to transfer business collaboration onto the Grid Complex relations between different Service Providers and their Business Processes have to be analysed and mapped to the grid Existing business models are usually broken down to business process models which have become a commodity Need of flexible adaptive ICT systems which understand business processes and can respond to changing business needs  A Modelling Framework supporting these tasks is needed

STASIS Open WorkshopPage 6 The Modelling Challenge in BREIN Modelling Framework has been defined to allow: Process oriented Requirements Analysis Specification of Software Architecture Externalization of Expert Know-How Based on the Scenarios with complex suppy Chains and inter-organisational collaboration the requirements were derived Modelling layers: Business Level: Supply Chains, Business Processes, and Goal Models IT-Level: Workflow and Service Description and Software Architecture Best Practise Roadmap

STASIS Open WorkshopPage 7 Best-Practice Roadmap Business Modelling Level CIM Software Architecture IT Modelling Level PSM, PIM Business Models Supply Chain- Modelling Business Process- Modelling Goal- Modelling Workflows and Service Description Workflows and Service Description Modelling methods to be considered: BPEL, SAWSDL, WSDL-S, OWL-S, OWL-WS, WS-CDL, WS-Agreement, WS-Agreement Negotiation, WSLA, WSMO, SWSF Modelling methods to be considered: UML 2.0 Modelling methods to be considered: SCOR ® Modelling methods to be considered: BPMN, E-BPMS, EPC, IDEF, LOVEM-E Modelling methods to be considered: GORE Vertical integration Vertical integration Horizontal integration Horizontal integration The BREIN Modelling Framework PROMOTE

STASIS Open WorkshopPage 8 The Modelling Challenge in BREIN Following Modelling Challenges have been identified 1. Syntactic Level: concerns models and their representation –Models are stored in different formats –no unified way to access them 2. Semantic Level: concerns the modelling languages and the integration of them –Integration of two modelling languages usually results in a gap –Example: “IT-Business gap” 3. Contextual Level: same term is used in different contexts –Example: Service Business expert: non-material equivalent of a good Technician: software that is deployed as a web service –Ambiguity is a mayor problem –common understanding of the domain between all stakeholders is essential

STASIS Open WorkshopPage 9 Topic 1 – Introduction Topic 4 – Conclusion and Outlook Topic 2 – The Modelling Challenge in BREIN Topic 3 – Addressing the BREIN Modelling Challenge

STASIS Open WorkshopPage 10 Addressing the BREIN Modelling Challenges 1.Syntactic Level: through the use of standards –One generic model repository acting as a mediator, all models stored in XML format –Model may be accessed through web service interfaces –Standard exchange formats such as EPC, UML/XMI, BPEL, OWL 2. Semantic Level: through Meta-model integration pattern –Modelling methods are coupled using a “transition layer” containing concepts form both worlds –Example: “IT-Business gap” 3. Contextual Level: through integration of meta-models and ontologies –Most difficult challenge –Bootstrapping approach: Models serve as basis for the generation of the ontology and vice versa –Definition of a Terminology to assist the user in modelling –Two related Modelling services available: Ontology Generator, Modelchecker

STASIS Open WorkshopPage 11 Contextual Challenge Ontology Generation (1) Use of models use of business process models for the generation of ontologies - filtering them according to relevant concepts and transformation into an ontology We distinguish two approaches: - ontology on a meta-model layer - ontology on a model layer BREIN Scenario Models BREIN-BML Meta-Model Virtual Engineering Scenario Models Airport Scenario Models Instantiation of Models Selected Meta- Model Concepts Ontologies BREIN Core Ontology BREIN Scenario Ontologies Selected Airport Concepts Selected Virt. Eng. Concepts Selection of generic concepts Business Modelling Language

STASIS Open WorkshopPage 12 Contextual Challenge Ontology Generation (2) Organisational model Ontology Automatic generation of Ontology

STASIS Open WorkshopPage 13 Contextual Challenge Ontology Generation (3) 13 Top-down by domain experts Bottom-up by knowledge engineers Modelling process using BPMS Modelling process using card sorting Ontology Domain feedback Ontology feedback Ontology input Domain input

STASIS Open WorkshopPage 14 Contextual Challenge Modelchecker (1) Checking the consistency of the models according to the terminology –ontology is considered complementary to models –defining the domain conceptually, contains the correct terminology and may serve as reference during modelling Ontology Modelling Modelcheck

STASIS Open WorkshopPage 16 Conclusion and Outlook (1) The BREIN Modelling Framework has been implemented trying to address the presented Modelling Challenges The Modelling Framework is currently in use by the project consortium Next steps include: Development of Best Practise Roadmap Development of additional Modelling Services Detailed definition of „Workflow and Services Description“ - Building Block Reference models for all related methods
