(Anglais) This paper presents an up-to-date comprehensive overview of MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique). MACBETH is a multicriteria decision analysis approach that requires only qualitative judgements about differences of value to help a decision maker, or a decision-advising group, quantify the relative attractiveness of options. The approach, based on the additive value model, aims to support interactive learning about the evaluation problem and the elaboration of recommendations to prioritise and select options in individual or group decision making processes. We revise in detail the theoretical foundations of MACBETH and present a simple example that illustrates the use of the M-MACBETH decision support system (www.m-macbeth.com). It permits the structuring of value trees, the construction of criteria descriptors, the scoring of options against criteria, the development of value functions, the weighting of criteria, and extensive sensitivity and robustness analyses about the relative and intrinsic value of options. Reference is also made to some successful real-world consulting applications and a historical survey is also included, which describes the key stages, with their corresponding publications, in the development of MACBETH since early the 1990's.
