Multi-Criteria Decision Making (MCDM) methods are techniques that facilitate decision-making in contexts where several criteria need to be evaluated simultaneously. This approach is key in complex situations, as it allows for the analysis of different aspects of a problem, such as technical, economic, social, and environmental factors, in an integrated manner. Within MCDM, there are different methods, with or without the intervention of expert groups, and each one offers a unique procedure for assigning weights and evaluating alternatives. MCDM are applied in various fields related to the optimal choice of alternatives in general. These methods are especially useful in decisions that involve both qualitative and quantitative factors, as they help structure the evaluation process, promoting transparency and consistency in comparisons between options. The ultimate purpose of MCDM is to offer a solid and systematic basis that allows decision-makers to identify the alternative that best fits their objectives and constraints, thus improving results in highly complex scenarios.
