  1. Agenda for Dec. 16th, 1999 meeting in Paris Meeting objective: draft major lines of road-map for the UEML Interest Group • UEML report by F. Vernadat • Presentation of members' views • Discussion of plans agreement on way to proceed • Delineate ISO and TF responsibilities research / standardisation UEML Group

  2. UEML Interest Group IFAC-IFIP Task Force (F. Vernadat, group leader) UEML Group

  3. UEMLUnified Enterprise Modelling Language Rationale: Towards an Esperanto in the area of Enterprise Modelling and Enterprise Engineering UEML Group

  4. UEMLUnified Enterprise Modelling Language The facts: • Too many EM languages • Unstable vocabulary and modelling paradigms • Many incompatible EM tools / weak process interoperation • Fragmented formal foundations of EM and EE However, all these tools "talk" about the same thing UEML Group

  5. Some well-known EM techniques • Data Flow Diagrams: SSAD, Yourdon, De Marco, … • Entity-relationship methods: MERISE, NIAM, M*, T-SER, … • SADT • IDEF suite of methods: IDEF0, IDEF1x and IDEF3 • GRAI nets • OMT and UML • CIMOSA • IEM • ARIS method • SA / RT • Harel's Statecharts • Activity-Based Costing methods UEML Group

  6. Some well-known EM tools • ARIS ToolSet • FirstSTEP • KBSI suite • NCR Metis • PrimeObjects • Bonapart • CimTool • … • Worfklow systems (WorkParty, IBM FlowMark, IBM VisualAge, Action Workflow, COSA, Ensemble, …) UEML Group

  7. Some well-known business users' complaints ·    Wide variety of available languages and technical approaches ·     Significant semantic gap between current mod. languages ·     Poor interoperation capability of process modelling & mgt tools ·     Insufficient coverage of modelling views as required by integrated systems engineering and management ·     Ignorance by most languages of so-called "soft issues" ·     Diversity of graphical notations (syntax) and multitude of meanings for similar concepts (inconsistent semantics) ·      Lack of a common standard language and exchange format  model exchange from one tool to another nearly impossible high potential for knowledge capitalisation annihilated UEML Group

  8. UEMLUnified Enterprise Modelling Language Consequences: Tower of Babel situation Refrained interest from business users UEML Group

  9. UEMLUnified Enterprise Modelling Language Earlier initiatives: • ICEIMT 97: identified the need for UEML and proposed a development framework • CEN work on ENV 12 204 • WfMC meta-model • ODP Enterprise Viewpoint • IEMC'99: reiterated the need for such a language • PSL: Process Specification Language (NIST initiative for manufacturing processes) UEML Group

  10. ICEIMT proposal for UEML development UEML Group

  11. PSL: Process Specification Language To provide a standard representation of process to allow companies to clearly and precisely document and share their manufacturing processes among different functions both within and among organisations. PSL: a language to be used as an interlingua to exchange process information among industrial applications UEML Group

  12. PSL Activity TimePoint Object Inf+ Inf- PSL: Process Specification Language (cont'd) • A process is one or more activities that accurs over a period of time in which objects participate. UEML Group

  13. UEMLUnified Enterprise Modelling Language IFAC-IFIP TF UEML Group Mandate (Beijing July 99): To define requirements and prepare the ground for a unification process that could lead to the development of a unified EM language by 1) Establishing working collaboration with all relevant groups in the area of enterprise modelling and simulation 2) Proposing a road-map that would lead to a technically feasible and politically acceptable EM solution for EE UEML Group

  14. UEMLUnified Enterprise Modelling Language What is UEML intended to be: Not the ultimate EM language to replace all previous ones But a standard meta-model (and underlying ontologies) widely accepted by business users and tool developers Easy to learn and to use with sufficient descriptive capabilities Consensus in the EM community (È or Ç) UEML Group

  15. UEMLUnified Enterprise Modelling Language Proposed Methodology: Year 1: • Identify and assess current EM languages • Identify and assess current EM tools and their constructs Year 2: • Develop a comparison matrix and relevant criteria • Identify and formally define the most relevant constructs Year 3: • Generalise and transfer results to standardisation level UEML Group

  16. UEMLUnified Enterprise Modelling Language Proposed Methodology (continued): Additional actions: • Establish liaison with other working groups (ODP, OMG, PSL/NIST, CDIF, …) • Involve tool developers and business users in the process UEML Group

  17. UEMLUnified Enterprise Modelling Language Work done so far: • Contact experts and form interest group • Collect information on tools (exploratory phase) • Collect information on languages (exploratory phase) • Establish contact with PSL (C. Schlenoff) • Get information on ODP Enterprise Language • Collect information on TOVE and other projects • Establish a French interest group on EM and EE UEML Group

  18. UEMLUnified Enterprise Modelling Language Modelling/language approaches considered so far: • CEN ENV 12 204 • CIMOSA • ODP Enterprise Language • WfMC meta-model • ARIS • IEM • IDEF suite • IDEF* • TOVE, Enterprise Ontology, I*, • PSL UEML Group

  19. Agent is executed by performs utilises Activity I/O object used by involved in made of Process made of Function raises triggers raises Event Environment happens at raises Time UEML: Starting point for UEML-core UEML Group

  20. UEMLUnified Enterprise Modelling Language Contributions received so far from TF members: • David Shorter, UK • Michael Gruninger, CDN • Ang Cheng Leong, SG • Mickael Petit, B Interest from 10 other members of the TF UEML Group

  21. Results achieved at Dec. 16th, 1999 meeting in Paris • Agree on the UEML IG mandate • Approve the road-map (to be detailed) • Clarify PSL vs. UML vs. UEML relationships and delineate ISO and TF responsibilities • Distribute work for next meeting (June 2000) • Agree to use UML + axiomatic specification to define the UEML language • Proposal to establish questionnaires • For tool vendors • For business users UEML Group
