TLDR
A new extension of the rough set model on the different universe is presented based on the fuzzy compatible relation R ∼ α, which is defined by a fuzzy relationship R ∼ between two different non-empty universes U and V and the threshold α.

A novel soft rough fuzzy set: Z-soft rough fuzzy ideals of hemirings and corresponding decision making

Jianming Zhan, +1 more
TL;DR: The notion of Z-soft rough fuzzy sets of hemirings is introduced, which is an extended notion of soft rough sets andrough fuzzy sets that removes the limiting condition that full soft sets require in Feng-soft rougher sets and Meng-soft Rough fuzzy sets.

Rough set-based conflict analysis model and method over two universes

Bingzhen Sun, +2 more
- 01 Dec 2016 - 
TL;DR: A new rough set model of conflict analysis: a conflict analysis decision model based on rough set theory over two universes, which could reveal the core causes for a conflict situation but also can find a possible optimal feasible consensus strategy to solve the conflict situation which satisfies the agents as much as possible.

Rough fuzzy sets and fuzzy rough sets

Didier Dubois, +1 more
- 01 Jun 1990 - 
TL;DR: It is argued that both notions of a rough set and a fuzzy set aim to different purposes, and it is more natural to try to combine the two models of uncertainty (vagueness and coarseness) rather than to have them compete on the same problems.

Rudiments of rough sets

Zdziasław Pawlak, +1 more
- 01 Jan 2007 - 
TL;DR: The basic concepts of rough set theory are presented and some rough set-based research directions and applications are pointed out, indicating that the rough set approach is fundamentally important in artificial intelligence and cognitive sciences.

Variable precision rough set model

Wojciech Ziarko
- 01 Feb 1993 - 
TL;DR: A generalized model of rough sets called variable precision model (VP-model), aimed at modelling classification problems involving uncertain or imprecise information, is presented and the main concepts are introduced formally and illustrated with simple examples.
