In systems engineering, the “system of interest” refers to the specific system that is the primary focus of attention, analysis, and engineering efforts within a particular context. It is the system that is being designed, developed, analyzed, or optimized to meet certain objectives or requirements. The concept of the system of interest is fundamental to the discipline of systems engineering and is used to define the boundaries and scope of the engineering efforts.
Key characteristics of the “system of interest” include:
- Definition of Boundaries: The system of interest is characterized by clear boundaries that distinguish it from its external environment. These boundaries help define what is included within the system and what lies outside of it.
- Components and Interactions: It consists of components (subsystems, elements, or parts) and their interactions that collectively contribute to the system’s purpose or function.
- Objectives and Requirements: The system of interest is designed to fulfill specific objectives or requirements. Understanding and documenting these objectives are crucial in the systems engineering process.
- Focus on Optimization: Systems engineering aims to optimize the performance of the system of interest by considering the relationships and trade-offs among its components.
- Lifecycle Considerations: The concept of the system of interest extends throughout the entire lifecycle of the system, from conceptualization and design to operation, maintenance, and eventual decommissioning.
- Context Dependency: The system of interest is defined within a specific context, which may include external systems, stakeholders, and environmental factors that interact with or influence the system.
The identification and understanding of the system of interest are foundational to effective systems engineering. It helps engineers and stakeholders establish a common understanding of the system’s goals, functions, and constraints, facilitating the development of solutions that meet the desired objectives.
