Q. Explain various types of system models.

There are different types of system modeling some are listed below with short described:

  1. Functional modeling
  2. Architectural Modeling (CPC)
  3. Business process modeling
  4. Enterprise modeling

Functional modeling:

        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 discovery of information needs, help identify opportunities, and establish a basis for determining product and service costs.


Architectural modeling[CPC]:

            A system architecture is a conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system. A system architecture can comprise system components that will work together to implement the overall system.


Business process modeling:

        Business process modeling (BPM) in systems engineering is the activity of  representing processes of an enterprise, so that the current process may be analyzed or improved. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter

experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both.


Enterprise modeling:

                Enterprise modeling is the abstract representation, description and definition of the structure, processes, information and resources of an identifiable business, government body, or other large organization. It deals with the process of understanding an enterprise business and improving its performance through creation of enterprise models
