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.
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]
In systems engineering, software engineering, and computer science, a function model or functional model is a structured representation of the functions (activities, actions, processes, operations) within the modeled system or subject area. [1] Example of a function model of the process of "Maintain Reparable Spares" in IDEF0 notation.
Modeling and simulation (M&S) is the use of models (e.g., physical, mathematical, behavioral, or logical representation of a system, entity, phenomenon, or process) as a basis for simulations to develop data utilized for managerial or technical decision making. [1] [2]
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.
Version 2.0 of BPMN was released in January 2011, [1] at which point the name was amended to Business Process Model and Notation to reflect the introduction of execution semantics, which were introduced alongside the existing notational and diagramming elements.
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]
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.
