Decoupling is the process of disentangling interconnected systems or variables, allowing them to function independently with minimal mutual influence. It finds application in physics, where weaker interactions are disregarded relative to dominant forces, simplifying system analysis. In economics, it suggests that economic growth and environmental sustainability can progress independently, aiming for reduced environmental impact per unit of output. Engineering employs decoupling to isolate components, preventing unwanted interactions or achieving specific performance goals. This concept is a versatile tool, Fee Management simplifying complex systems and enabling targeted optimization in various fields, including physics, economics, and engineering.
