If a set of instruments are integrated to perform the certain task independently or with mutual interaction, that set of instruments is called as a system. System modeling is designing the system architecture with clear vision, analysis, and expression to give the desired output.
Modeling of a System
This designing can be done for one system or a set of systems. This is more simple economical and reliable. For modeling a system conceptualisation of a framework is essential. Secondly, a modeling language needs to be prepared. This is generally done in the form of pure text or diagrams or, sometimes, a combination of both. Till now four types of frameworks have been conceptualized and prepared for effective usage. They are module interconnection language, software architecture, design methods and design pattern. The selection of framework and its complexity depends upon the sector it is intended for.
Types of Modelling and Applications
IT and business sectors use this modeling of systems to a greater extent. Modeling of different systems is done with different complexity scale and scope. Modelings are basically three types. They are enterprise modeling, business process modeling, and functional modeling. Enterprise modeling is an abstract representation of operations or functions of a financial organization. Any financial organization includes several operations like purchases, resource managements, production, and sales. If all these operations, combined or independently, are conceptualized and represented within a specific framework that is called enterprise modeling.
Business Process Modelling
Business process modeling includes aspects of a business organization. They are like business strategies, offerings, the purpose of business, trading, and policies. Because of its complexity, business process modeling is further divided into several parts. Functional modeling, as the name suggests, is basically for organizations and business processes. It is a graphical representation of functioning of a business or an organization or a government. Functional modeling is an integral part of modeling of several another modeling. System modeling can be further divided into several parts such as operational research modeling, soft system modeling, hard system modeling and system analysis.
