Core Concepts of the Systems Approach
The core concepts of the Systems approach encompass the fundamental categories, principles, and tools used for describing, modeling, researching, and managing complex systems. These concepts serve as the foundational framework for Systems thinking, systems design, and decision-making under conditions of uncertainty and complexity.
