  2. IDEF0 - Wikipedia

    en.wikipedia.org/wiki/IDEF0

    IDEF0, used to produce a "function model". A function model is a structured representation of the functions, activities or processes within the modeled system or subject area. [5] IDEF1, used to produce an "information model". An information model represents the structure and semantics of information within the modeled system or subject area. [6]

  3. Function model - Wikipedia

    en.wikipedia.org/wiki/Function_model

    [1] Example of a function model of the process of "Maintain Reparable Spares" in IDEF0 notation. A function model, similar with the activity model or process model, is a graphical representation of an enterprise's function within a defined scope. The purposes of the function model are to describe the functions and processes, assist with ...

  4. Systems modeling - Wikipedia

    en.wikipedia.org/wiki/Systems_modeling

    Business Process Modeling Notation Example. Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. [2] A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0.

  5. IDEF1X - Wikipedia

    en.wikipedia.org/wiki/IDEF1X

    A meta model is a model of the constructs of a modeling system. Like any model, it is used to represent and reason about the subject of the model - in this case IDEF1X. The meta model is used to reason about IDEF1X, i.e., what the constructs of IDEF1X are and how they relate to one another. The model shown is an IDEF1X model of IDEF1X.

  6. IDEF - Wikipedia

    en.wikipedia.org/wiki/IDEF

    IDEF refers to a family of modeling language, which cover a wide range of uses, from functional modeling to data, simulation, object-oriented analysis/design and knowledge acquisition. Eventually the IDEF methods have been defined up to IDEF14: IDEF0: Function modeling [1] IDEF1: Information modeling [2] IDEF1X: Data modeling [3]

  7. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    In the next, the so-called first level—DFD 1—the numbering continues For example, process 1 is divided into the first three levels of the DFD, which are numbered 1.1, 1.2, and 1.3. Similarly, processes in the second level (DFD 2) are numbered 2.1.1, 2.1.2, 2.1.3, and 2.1.4. The number of levels depends on the size of the model system.

  8. Enterprise modelling - Wikipedia

    en.wikipedia.org/wiki/Enterprise_modelling

    A function model, also called an activity model or process model, is a graphical representation of an enterprise's function within a defined scope. The purposes of the function model are: to describe the functions and processes, assist with discovery of information needs, help identify opportunities, and establish a basis for determining ...

  9. Business Process Model and Notation - Wikipedia

    en.wikipedia.org/wiki/Business_Process_Model_and...

    Business Process Model and Notation (BPMN) is a graphical representation for specifying business processes in a business process model. Originally developed by the Business Process Management Initiative (BPMI), BPMN has been maintained by the Object Management Group (OMG) since the two organizations merged in 2005.
