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 ... -
Estimating Fuzzy Life Time with a Fuzzy Reliability Function in the Appliance Sector
Erginel, Nihal; Saraçoğlu, Hande; Yıldız, Gülay; Şentürk, Sevil (Springer International Publishing Ag, 2018)Reliability is defined as the length of time a component works without failing. The reliability function shows an estimate for the probable amount of time a component should work without experiencing failure. Fuzzy set ... -
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 ... -
Evaluating the Packing Process in Food Industry Using Fuzzy X ~ and S ~ Control Charts
Erginel, Nihal; Şentürk, Sevil; Kahraman, Cengiz; Kaya, İhsan (Atlantis Press, 2011)The fuzzy set theory addresses the development of concepts and techniques for dealing with uncertainty or impression conditions. If the collected data from a process include vagueness due to human subjectively or measurement ... -

Fuzzy Dea Approach to Solve the Location Selection of Wind Energy
Erginel, Nihal; Yalçınkaya, Merve; Şentürk, Sevil (World Scientific Publ Co Pte LTD, 2012)Wind energy is an important energy source among the renewable energies, in nowadays. Turkey has many wind energy locations due to the appropriate weather conditions. The problem of location selection of wind energy depends ... -
Fuzzy EWMA and Fuzzy CUSUM Control Charts
Erginel, Nihal; Şentürk, Sevil (Springer Int Publishing Ag, 2016)Exponentially Weighted Moving- Averages (EWMA) and Cumulative-Sum (CUSUM) control charts have the ability of detecting small shifts in the process mean. Classical EWMA and CUSUM charts are not capable to capture the ... -
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 ... -
