Reference Model

Definition

A reference model is a conceptual framework that defines the structure, components, and relationships of a system, often used to establish guidelines for designing and implementing control systems. It serves as a baseline for comparison and understanding, facilitating communication between various stakeholders involved in system development. By outlining a standard approach, reference models help to clarify roles, responsibilities, and interactions within a control system.
