[HTML][HTML] Revision of the Kosiński's theory of ordered fuzzy numbers

K Piasecki - Axioms, 2018 - mdpi.com
Ordered fuzzy numbers are defined by Kosiński. In this way, he was going to supplement a
fuzzy number by orientation. A significant drawback of Kosiński's theory is that there exist …

The directed compatibility between ordered fuzzy numbers-a base tool for a direction sensitive fuzzy information processing

P Prokopowicz, W Pedrycz - Artificial Intelligence and Soft Computing: 14th …, 2015 - Springer
Abstract The Ordered Fuzzy Numbers (OFN) were defined over 10 years ago as a tool for
processing fuzzy numbers. This model has an additional feature used in processing, namely …

The use of ordered fuzzy numbers for modelling changes in dynamic processes

P Prokopowicz - Information Sciences, 2019 - Elsevier
This paper presents an efficient use of the Ordered Fuzzy Numbers model in the description
of processes undergoing dynamic changes. The purpose of this model is to provide a …

The directed inference for the Kosinski's fuzzy number model

P Prokopowicz - Proceedings of the Second International Afro …, 2016 - Springer
Abstract The Kosinski's Fuzzy Number (KFN) model (former name the Ordered Fuzzy

[HTML][HTML] Relation “greater than or equal to” between ordered fuzzy numbers

K Piasecki - Applied System Innovation, 2019 - mdpi.com
The ordered fuzzy number (OFN) is determined as an ordered pair of fuzzy number (FN) and
its orientation. FN is widely interpreted as imprecise number approximating real number. We …

This chapter presents a trend phenomenon and application of the fuzzy controller for
Ordered Fuzzy Numbers (OFNs). The authors propose to use a trend in a combustion …

Oriented fuzzy numbers vs. fuzzy numbers

K Piasecki, A Łyczkowska-Hanćkowiak - Mathematics, 2021 - mdpi.com
A formal model of an imprecise number can be given as, inter alia, a fuzzy number or
oriented fuzzy numbers. Are they formally equivalent models? Our main goal is to seek …

[HTML][HTML] Representation of Japanese candlesticks by oriented fuzzy numbers

K Piasecki, A Łyczkowska-Hanćkowiak - Econometrics, 2019 - mdpi.com
The Japanese candlesticks' technique is one of the well-known graphic methods of dynamic
analysis of securities. If we apply Japanese candlesticks for the analysis of high-frequency …

Aggregation operator for ordered fuzzy numbers concerning the direction

P Prokopowicz, SMM Golsefid - … , ICAISC 2014, Zakopane, Poland, June 1 …, 2014 - Springer
Abstract Ordered Fuzzy Numbers (OFN) were proposed about 10 years ago [7, 8] as a tool
for the calculations of imprecise values represented by fuzzy numbers. Calculation methods …
