Preference disaggregation analysis (PDA) is an approach in multicriteria decision analysis that aims to extract preferential information from holistic judgments provided by decision-makers. This paper presents an original methodology for PDA that addresses two challenges in this field. First, we consider the structure of the data as a tensor within the context of PDA to capture decisionmakers' preferences based on descriptive measures of the criteria time series, such as trend and average. This approach enables an understanding of decision-makers' preferences in scenarios involving time series analysis, which is common in medium- to long-term impact decisions. Second, the paper addresses the robustness concern in PDA methods, which involves dealing with multiple compatible models reflecting the decision-maker's preferences, using a multi-objective model. This approach allows for identifying multiple preference models and provides a mechanism to converge towards the most likely preference model. The proposed method is evaluated using real data. Results show that the decision-maker's preference for a criterion can vary based on descriptive measures. This highlights the importance of considering both the criterion and the descriptive measures in the decision problem. The multi-objective analysis produces multiple solutions and, under specific conditions, can lead to a single solution reflecting the decisionmaker's preferences. (AU) | |
