The connections of vague set and rough set
Abstract
Purpose
The purpose of this paper is to present research methods in processing uncertain information.
Design/methodology/approach
Vague set and rough set are both‐wings‐mode for expressing uncertainty systems, and based on the both‐wings‐mode of expressing uncertainty systems, the connections of vague set and rough set are discussed.
Findings
This paper presents the relationships between vague set and rough set.
Research limitations/implications
Based on these connections between vague set and rough set, theoretical and means of vague set can be used for rough set; also theoretical and means of rough set can be used for vague set.
Originality/value
The paper contributes to the discussion on the research of vague set and rough set. The conclusions are useful in information processing.
