Weighted sum model

The Weighted Sum Model (WSM) is a simple and commonly used multi-criteria decision-making (MCDM) method. It helps decision-makers to evaluate and prioritize alternatives based on multiple criteria by aggregating the different criteria scores into a single score. The WSM is particularly useful when criteria are measured in different units or when comparing different options based on various attributes. ### Key Components of the Weighted Sum Model: 1. **Alternatives**: These are the different options or choices being evaluated.
