Abstract

Recent research has highlighted the importance of studying the different forms of monotonicity for various discrete Choquet-like integrals in the field of data aggregation and its real-world applications. In this paper, we focus on the standard monotonicity condition for two operators encompassing many modifications of the discrete Choquet-like integral known in the literature, such as the CQO-integral, the CT-integral, the CC-integral, the CO-integral, or the n-ary discrete d-Choquet integral. Using a new approach, we provide complete monotonicity characterizations for both operators. This, in turn, allows us to give full characterizations of the operators as aggregation functions. Our results extend and complete some results in the literature.
