Description: The yield ratio measures the efficiency of an investment or process in producing results. This concept is fundamental in various disciplines, including economics, engineering, and project management. It is generally expressed as a ratio that compares the results obtained with the resources invested, thus allowing for the evaluation of the effectiveness of a strategy or action. A high yield ratio indicates that good results are being achieved with a reasonable amount of resources, while a low ratio suggests inefficiency. This indicator is crucial for decision-making, as it enables organizations to identify areas for improvement and optimize their processes. Furthermore, the yield ratio can be used to compare different investment alternatives or strategies, facilitating the selection of the most efficient option. In the context of model optimization, this concept becomes an essential tool for adjusting parameters and improving the overall performance of a system, ensuring that resources are used as effectively as possible.
