An Application of Fuzzy Coding in Multiple Correspondence Analysis for Transforming Data from Continuous to Categorical
Aşan, Zerrin; Şentürk, Sevil (Old City Publishing Inc, 2012)In some research, it can be necessary to know the categorical data groups to which the data measured by interval and ratio scale belong. The fuzzy sets principle can be used to transform the original continuous data into ... -
Bulanık mantıkta korelasyon katsayısı; meterolojik olaylarda bir uygulama
Şentürk, Sevil; Aşan, Zerrin (2007)Korelasyon iki yada daha çok sayıda değişken arasındaki ilişkiyi göstermekte ilişki miktarı ise korelasyon katsayısı ile belirlenmektedir. İki değişken arasındaki doğrusal ilişkinin derecesini belirleyen korelasyon katsayısını ... -
Design of Fuzzy (u)over-tilde Control Charts
Şentürk, Sevil; Erginel, Nihal; Kaya, İhsan; Kahraman, Cengiz (Old City Publishing Inc, 2011)When expressing any data in linguistic terms related to a quality characteristic, traditional statistical techniques are insufficient to capture the vagueness in the data. Linguistic data can be transformed into numerical ... -
Design of Fuzzy u Control Charts
When expressing any data in linguistic terms related to a quality characteristic, traditional statistical techniques are insufficient to capture the vagueness in the data. Linguistic data can be transformed into numerical ... -
Development of fuzzy ((X) over bar) over tilde - (R) over tilde and ((X) over bar) over tilde - (S) over tilde control charts using alpha-cuts
Şentürk, Sevil; Erginel, Nihal (Elsevier Science Inc, 2009)Statistical process control (SPC) is an approach that uses statistical techniques to monitor the process. Shewhart introduced the control charts that are one of the most important techniques of quality control to detect ... -
An Estimation Method of Membership Function for Given Fuzzy Data
Samilov, Aladdin; Şentürk, Sevil; Ince, Nihal (Yildiz Technical University, 2017)In the present study for given fuzzy data an estimation method based on Max(F)Ent measure and generalized entropy optimization methods is suggested. A set of successive values of estimated membership function is defined ... -
A framework for fuzzy variable control charts with ?-cuts
Şentürk, Sevil; Erginel, N. (2007)In traditional variable control charts, center line, upper control limit and lower control limit are crisp values. In this situation, process are defined "in control" or "out of control" with depending on observation values ... -
Fuzzy exponentially weighted moving average control chart for univariate data with a real case application
Şentürk, Sevil; Erginel, Nihal; Kaya, İhsan; Kahraman, Cengiz (Elsevier Science BV, 2014)Statistical process control (SPC) is an approach to evaluate processes whether they are in statistical control or not. For this aim, control charts are generally used. Since sample data may include uncertainties coming ... -
Fuzzy regression control chart
Şentürk, Sevil (World Scientific Publ Co Pte LTD, 2008)The fuzzy set theory is a powerful method to analyze the statistical data which includes ambiguity or vague comes from the structure of the process, measurement systems or environmental conditions. Crisp value collected ... -
Interval Type-2 Fuzzy Analytic Network Process for Modelling a Third-party Logistics (3PL) Company
Şentürk, Sevil; Erginel, N.; Binici, Y. (Old City Publishing Inc, 2017)The Fuzzy Analytic Network Process (ANP) is generally used for solving multi-criteria decision making (MCDM) problems by considering the pairwise comparison between criteria/sub-criteria, and inner/outer dependencies among ... -
Interval Type-2 Fuzzy c-Control Charts: An Application in a Food Company
Şentürk, Sevil; Antucheviciene, Jurgita (Inst Mathematics & Informatics, 2017)Many papers exist on ordinary fuzzy control charts in literature in order to consider the vagueness and uncertainty in observation data. These are on both variable and attribute control charts. Several extensions of fuzzy ... -
A New Approach for Parameter Estimation in Fuzzy Logistic Regression
Atalık, Özlem; Şentürk, Sevil (University Sistan & Baluchestan, 2018)Logistic regression analysis is used to model categorical dependent variable. It is usually used in social sciences and clinical research. Human thoughts and disease diagnosis in clinical research contain vagueness. This ... -
The theoretical structure of Fuzzy Analytic Network Process (FANP) with Interval Type-2 Fuzzy Sets
Şentürk, Sevil; Binici, Yonca; Erginel, Nihal (Elsevier Science BV, 2016)The Fuzzy Analytic Network Process has solved multi-criteria decision making problems. Type-1 fuzzy sets used defining as expert's linguistic judgement because fuzzy set theory is concerned with uncertainty in human thought ...
