Axiomatic approaches to rough approximation operators via ideal on a complete completely distributive lattice

Methodologies and Application

Abstract

In 2014, Zhou and Hu (Inf Sci 269:378–387, 2014) introduced a kind of rough sets on a complete completely distributive lattice (short for CCD lattice), which can be seen as a unified framework for the study of rough sets based on ordinary binary relations, rough fuzzy sets and interval-valued rough fuzzy sets. Han et al. (Soft Comput 20:1853–1861, 2016) introduced a new pair of rough approximation operators via ideal on a CCD lattice in 2016, which is more general and accurate than Zhou and Hu’s. In this paper, we further investigate its properties, and then the axiomatic approaches are studied. Through some of our axioms, the rough approximations via ideal on a complete atomic Boolean lattice can be viewed as special cases of rough approximation operators via ideal on a CCD lattice if the ideal is well given.
