Generalized attitudinal Choquet integral

Abstract

Attitudinal Choquet integral (ACI) extends Choquetintegral (CI) through a consideration of a decision‐maker’s (DM’s) attitudinal character. In this paper, wegeneralize ACI, and the resulting operator is termed asgeneralized ACI (GACI). GACI adds to the efficacy ofthe ACI in the representation of a DM’s unique andcomplex attitudinal character. It also generates a vastrange of exponential ACI operators, such as harmonicACI, ACI, quadratic ACI, to name a few. We furtherpresent induced GACI to consider additional informa-tion that may be associated with the arguments ofaggregation. The special cases of the proposed operatorsare investigated. The usefulness of the proposedoperators in modelling human decision behavior isshown through a case study.
