Detection of decision-making manipulation in the pairwise comparisons method

Michał Strada, Sebastian Ernst, Jacek Szybowski, Konrad Kułakowski

Most decision-making models, including the pairwise comparison method, assume the decision-makers honesty. However, it is easy to imagine a situation where a decision-maker tries to manipulate the ranking results. This paper presents three simple manipulation methods in the pairwise comparison method. We then try to detect these methods using appropriately constructed neural networks. Experimental results accompany the proposed solutions on the generated data, showing a considerable manipulation detection level.
