Classification of non-pharmaceutical anti-COVID ınterventions based on novel FTOPSIS-sort models
Radaev, Alexander; Haktanır, Elif; Yatsalo, Boris; Kahraman, Cengiz (Springer Science and Business Media Deutschland GmbH, 2022)Assigning alternatives to predefined ordered categories under multicriteria conditions is the essence of multi-criteria sorting problematic. The family of fuzzy multi-criteria sorting models with the common name FTOPSIS-Sort ... -
Defects control charts using interval-valued penthagorean fuzzy sets
Haktanır, Elif; Kahraman, Cengiz (Springer, 2021)Defects control charts are one of the attributes control charts which are constructed based on the number of defects on a product or in an inspection unit. Since the term ‘defect’ can be vague due to the subjective decisions ... -
Delivery drone design using spherical fuzzy quality function deployment
Haktanır, Elif; Kahraman, C.; Kutlu Gündoğdu, F. (Springer, 2021)Quality Function Deployment (QFD) is a well-known structured approach meeting customer needs through technical applications. Customer requirements (CRs) for a delivery drone design are first determined and they are tried ... -
Design for six sigma and process capability using penthagorean fuzzy sets
Haktanır, Elif; Kahraman, C. (Springer, 2021)Design for six sigma (DFSS) is a structured approach for designing new products, processes and/or services or redesigning the existing ones. It builds quality into the product during the development and ensures the customer ... -
Failure mode and effect analysis using interval valued neutrosophic sets
Haktanır, Elif; Kahraman, C. (Springer Verlag, 2020)Failure mode and effects analysis (FMEA) is an effective analysis method to identify and rank the potential failure modes. Since traditional FMEA is inadequate to represent the vagueness in human decisions and evaluations, ... -
A fuzzy film rating system using penthagorean fuzzy K-means clustering
Haktanır, Elif (Journal of Multiple-Valued Logic & Soft Computing, 2021)K-means clustering is one of the most popular clustering algorithms, which defines k number of clusters by minimizing the distances between cluster centers and the data points. If the data points include any level of ... -
Fuzzy multi-criteria sorting models FMAVT-Sort and FTOPSIS-Sort: features and application within the case studies
Radaev, Alexander; Haktanır, Elif; Yatsalo, Boris; Kahraman, Cengiz (Springer Science and Business Media Deutschland, 2023)The need to sort alternatives according to ordered categories, especially in problems consisting of a large number of alternatives, makes it effective to use of multi-criteria sorting methods. A family of fuzzy multi-criteria ... -
Interval valued pythagorean fuzzy aggregation operators based Malcolm Baldrige National Quality Award assessment
Haktanır, Elif (Ios Press, 2020)Malcolm Baldrige National Quality Award (MBNQA) is a quality assessment and rewarding system that aims to increase the awareness of quality management. Although the award is launched in the USA in 1989 and only given to ... -
Interval-valued neutrosophic failure mode and effect analysis
Haktanır, Elif; Kahraman, Cengiz (Ios Press, 2020)Failure mode and effects analysis (FMEA) is a structured approach for discovering possible failures that may occur in the design of a product or process. Since classical FMEA is not sufficient to represent the vagueness ... -
Interval-valued neutrosophic hypothesis testing
Haktanır, Elif (Ios Press, 2020)Hypothesis testing is an important tool of statistical decision making. Classical hypothesis testing is based on a known probability distribution with known population parameters. However, since the data generally include ... -
A literature review on fuzzy FMEA and an application on infant car seat design using spherical fuzzy sets
Haktanır, Elif; Kahraman, C. (Springer, 2020)Failure mode and effects analysis (FMEA) is a structured approach to determine the potential failures that may arise during the implementation of a process. Because of the vagueness and impreciseness in the definition of ... -
Make-or-buy decision using interval-valued intuitionistic fuzzy COPRAS method
Haktanır, Elif (Springer Verlag, 2020)One of the central issues in strategic management is the determination of a firm’s vertical boundaries. Since almost all the publications in the literature are based on crisp measurements and evaluations for make-or-buy ... -
Malcolm baldrige national quality award assessment using interval valued pythagorean fuzzy sets
Haktanır, Elif; Kahraman, C. (Springer Verlag, 2020)Malcolm Baldrige National Quality Award (MBNQA) is a highly acknowledged performance excellence model. Since almost all the publications in the literature are based on crisp measurements and evaluations of the system ... -
New product design using Chebyshev’s ınequality based ınterval-valued ıntuitionistic z-fuzzy qfd method
Haktanır, Elif (Vilnius University, 2022)Abstract. In Quality function deployment (QFD) approach, customers tend to express their needs in linguistic terms rather than exact numerical values and these needs generally contain vague and imprecise information. To ... -
A novel CRITIC based weighted FMEA method: Application to COVID-19 blood testing process
Haktanır, Elif; Kahraman, Cengiz (Journal of Multiple-Valued Logic & Soft Computing, 2021)Prioritizing the risk factors in production and service processes has a great importance since limited resources must be well managed. Classical Failure Mode and Effects Analysis (FMEA) is the most used method for this ... -
A novel feature to predict buggy changes in a software system
Yılmaz, Rahime; Haktanır, Elif; Nalçakan, Yağız (Springer, 2021)Researchers have successfully implemented machine learning classifiers to predict bugs in a change file for years. Change classification focuses on determining if a new software change is clean or buggy. In the literature, ... -
A novel interval-valued pythagorean fuzzy QFD method and its application to solar photovoltaic technology development
Haktanır, Elif; Kahraman, Cengiz (Pergamon-Elsevier Science Ltd, 2019)Quality function deployment (QFD) is a focused methodology for carefully listening to the voice of the customer and then effectively responding to those needs or customer requirements, (CRs) and expectations through design ... -
A novel picture fuzzy CRITIC & REGIME methodology: Wearable health technology application
Haktanır, Elif; Kahraman, Cengiz (2022)Picture fuzzy sets (PFSs) are one of the most promising extensions of ordinary fuzzy sets with three parameters, namely positive membership, neutral membership, and negative membership, for defining the membership status ... -
