The paper is devoted to the application of the integral transform for lattice-valued functions, which is based on a Sugeno-like fuzzy integral, to multicriteria decision making. We present an integral transform defined within the space of functions whose values belong to a complete residuated lattice. We use this integral transform as an extended qualitative aggregation operator in multicriteria decision making to get the evaluation of alternatives for a decision-maker. The proposed approach is illustrated and compared with a common approach on a car selection problem.
