What is MACBETH?

Measuring Attractiveness through a Category Based Evaluation Technique is the goal of the MACBETH approach. It permits the evaluation of options against multiple criteria. The key distinction between MACBETH and other Multiple Criteria Decision Analysis (MCDA) methods is that it needs only qualitative judgements about the difference of attractiveness between two elements at a time, in order to generate numerical scores for the options in each criterion and to weight the criteria. The seven MACBETH semantic categories are: no, very week, weak, moderate, strong, very strong, and extreme difference of attractiveness.

As the judgements expressed by the evaluator are entered in the M-MACBETH software (www.m-macbeth.com), their consistency is automatically verified and suggestions are offered to resolve inconsistencies if they arise. The MACBETH decision aid process then evolves into the construction of a quantitative evaluation model. Using the functionalities offered by the software, a value scale for each criterion and weights for the criteria are constructed from the evaluator's semantic judgements. The value scores that reflect their attractiveness taking all the criteria into consideration. Extensive analysis of the sensitivity and robustness of the model's results with then provide a deeper understanding of the problem, contributing to attain a requisite evaluation model: a sound basis to prioritise and select options in individual or group decision-making contexts.
