How is a formal system defined in systems engineering?

In systems engineering, a formal system is defined as an integrated set of elements achieving a defined objective. This concept emphasizes the importance of coherence and integration among the various components that make up a system. Each element in this context contributes to the overall purpose of the system, ensuring that all parts work together harmoniously to fulfill the objectives set forth.

The definition highlights that a successful system is more than just a compilation of parts; it requires organization, interaction, and functionality that align with specific goals. This integration is crucial for optimizing performance, managing dependencies, and ensuring that the system can effectively address the challenges it is designed to solve. This understanding is foundational in systems engineering, where the focus is on creating systems that are not only functional but also efficient and effective in achieving their intended purposes.
