Abstract
In this paper, we present a review of research on the applications of fuzzy set theory conducted by Lublin University of Technology researchers. We focus on analyzing research trends and practical applications of fuzzy sets in time series analysis and missing data imputation. Fuzzy sets constitute a key methodology for addressing data uncertainty and imprecision. We discuss various techniques within the field of fuzzy sets, including fuzzy classification, outlier detection, and missing data imputation, emphasizing their significance across various fields of science and social life. The presented results indicate the potential for innovative research and further development in this field. The academic community at Lublin University of Technology plays a significant role in promoting and advancing fuzzy set theory, which is crucial for future scientific and technological research.
