Weighted Sum Method
The Weighted Sum Method is a multi-criteria decision-making (MCDM) technique used to evaluate and rank alternatives based on multiple criteria by assigning weights to each criterion and summing the weighted scores. It involves normalizing criterion values, applying weights to reflect their relative importance, and calculating a total score for each alternative to determine the best option. This method is widely applied in fields like engineering, economics, and operations research for objective decision-making.
Developers should learn the Weighted Sum Method when building systems that require automated decision-making, such as recommendation engines, resource allocation tools, or optimization algorithms, as it provides a straightforward way to incorporate multiple factors into a single metric. It is particularly useful in scenarios where trade-offs between different criteria need to be quantified, such as in project prioritization, feature selection, or performance evaluation, helping to make data-driven choices efficiently.
