Systems modeling
Systems modeling or systems modelling is the interdisciplinairy 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 modelling, 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.
Overview
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 interdisciplinairy 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:
In "Methodology for Creating Business Knowledge" (1997) Arbnor and Björn Bjerke|Bjerke]] the systems approach (systems modeling) was considered to be one of the three basic methodological approaches for gaining business knowledge, beside the analytical approach and the actor's approach (agent based modeling).[3]
Types of systems modeling
In business and IT development systems are modelled with different scoops and scales of complexity, such as:
Further more like systems thinking, systems modeling in can be devided into:
- Systems analysis
- Hard systems modeling or operational research modeling
- Soft system modeling
And all other specfic types of systems modeling, such as form example complex systems modeling, dynamical systems modeling, and critical systems modeling.
