3- 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. These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition.
The Business Process Modeling Notation (BPMN), a graphical representation for specifying business processes in a workflow, can also be considered to be a systems modeling language.
In business and IT development the term "systems modeling" has multiple meaning. It can relate to:
the use of model to conceptualize and construct systems
the interdisciplinary study of the use of these models
the systems modeling, analysis, and design efforts
the systems modeling and simulation, such as system dynamics
any specific systems modeling language
As a field of study systems modeling has emerged with the development of system theory and systems sciences.
As a type of modeling systems modeling is based on systems thinking and the systems approach. In business and IT systems modeling contrasts other approaches such as:
agent based modeling
data modeling and
mathematical modeling
