Product-line planning under uncertainty Karakaya, Şakir; Köksal, Gülser (2022-02-01) This study addresses a multi-period product-line-mix problem considering product interdependencies and uncertainties regarding price, demand, production cost, and the cannibalization effect of new products. The problem is ...
Multivariate quality loss function cost parameter estimation Köksal, Gülser; Dolgun, Leman Esra (2021-08-23) In this study, we consider estimating the cost matrix parameters of the multivariate quality loss function which is commonly used in product and process design parameter optimization. Multivariate quality loss functions co...
Kategorik yanıta sahip tasarım parametresi eniyilemesi için yeni bir metot Erdoğan, Pınar; Köksal, Gülser; Dolgun, Leman Esra (2021-07-04) Bir ürün veya sürecin girdi, süreç veya çevre faktörlerindeki değişkenliğe karşı duyarsız en iyi parametre değerlerini elde etmek önemli bir tasarım problemidir. Bu nedenle, birçok endüstriyel organizasyon robust parametre...
Dijital dönüşüm mühendisliği nasıl dönüştürüyor? Köksal, Gülser (2021-04-01) Dijitalizasyon ve dijital dönüşüm günümüzde sıkça duyduğumuz kavramlar haline geldi. Dijitalizasyon, dijital teknolojilerin kullanımı ile iş modellerini yeni değer ve gelir üretecek şekilde değiştirmeye yarıyor. Dijital dö...
A method for robust design of products or processes with categorical response Erişkin, Levent; Dolgun, Leman Esra; Köksal, Gülser (2021-01-01) © 2021 Taylor & Francis Group, LLC.In many industries, quality characteristics are measured as ordered categorical responses due to measurement difficulties, or for cost-effectiveness. Although various approaches have been...
AN APPROACH FOR DETERMINING THE COST MATRIX OF MULTIVARIATE QUALITY LOSS FUNCTION Dolgun, Leman Esra; Erişkin, Levent; Özkan, Gökçe; Köksal, Gülser (2020-11-01) Multivariate quality loss functions are commonly used in product and process design parameter optimization, which involves simultaneous consideration of multiple responses in determination of the levels of design parameter...
An Approach for Monitoring of Long-Run Product Development Projects for Quality DOLGUN, LEMAN ESRA; Köksal, Gülser (2020-09-22)
Representing preferences by choquet integral: Guidelines to specify the capacity type Dolgun, Leman Esra; Burnak, Nimetullah; Köksal, Gülser (Growing Science, 2020-06-01) © 2020 by the authors; licensee Growing Science, Canada.This study considers representing decision maker preferences by Choquet integral in existence of interactions among criteria. Parameters of the Choquet integral are c...
Generalized desirability functions: a structural and topological analysis of desirability functions Akteke-Öztürk, Başak; Weber, Gerhard-Wilhelm; Köksal, Gülser (Informa UK Limited, 2020-01-02) We have Derringer and Suich’s desirability functions in mind,especially, the two-sided ones in our analysis throughout thisstudy. We propose and develop a finite partitioning procedureof the individual desirability functio...
