In industrial quality improvement and design studies, an important aim is to improve the product or process quality by determining factor levels that would result in satisfactory quality results. In these studies, quality characteristics that are qualitative are often encountered. Although there are many effective methods proposed for parameter optimization (robust design) with continuous responses, the methods available for qualitative responses are limited. In this study, a parameter optimization method for solving binary response robust design problems is proposed. The proposed method uses Mahalanobis Taguchi System to form a classification model that provides a distance function to separate the two response classes. Then, it finds the product/process variable settings that minimize the distance from the desired response class using quadratic programming. The proposed method is applied on two cases previously studied using Logistic Regression. The classification models are formed and the parameter optimization is conducted using the formed MTS models. The results are compared with those of the Logistic Regression. Conclusions and suggestions for future work are given.

Selecting quality improvement projects and product mix together in manufacturing: an improvement of a theory of constraints-based approach by incorporating quality loss Köksal, Gülser (Informa UK Limited, 2004-12-01) The quality of products and processes needs to be improved continuously in today's competitive environments. Unless these improvement efforts are focused properly, companies might not achieve desirable results in terms of sales, quality and productivity. Many quality improvement (QI) approaches have a limited evaluation of the factors involved in the selection of QI projects. Theory of constraints (TOC) has been proposed by some researchers as a remedy for the better selection of QI projects. However, these...
The effect of inspection error on quality and producer losses: the case of nominal-the-best type quality characteristic and rework Köksal, Gülser; Dolgun, Leman Esra; Batmaz, İnci (Inderscience Publishers, 2013-01-01) In this study, the effect of inspection error (IE) on quality and producer losses is investigated for a nominal-the-best type quality characteristic determined by a manufacturing process centre with a separate rework unit. The probability distribution and the first two moments of the resulting quality characteristic values are derived and used together with Markov chain models and simulation to study the quality and producer losses and the related statistics for various processes and gage capability levels....
A decision support system for production planning and pre-cost estimation activities in an apparel company Gökalp, Ebru; Şen, Tayyar; Department of Industrial Engineering (2010) In this study, a specific decision support system is designed and developed for Production Planning and Marketing Department of an apparel company. The developed system involves two modules with user friendly interface or data input and query. The system is designed to provide support in the following fields of decision making; pre cost estimation, capacity planning, master production planning and production scheduling. A detailed analysis of the existing system is conducted and Microsoft Access is used for...
The influence of product appearance on perceived product quality in reference to washing machines Veyisoğlu, Ahmet Burak; Hasdoğan, Gülay Fatma; Department of Industrial Design (2010) Product quality is regarded as one of the most important factors that consumers consider while purchasing products. However, contrary to objective quality, perceived product quality includes consumer's judgment about the overall superiority or excellence of a product. This study mainly concentrates on the relationship between product appearance and perceived product quality especially for durable goods. The definitions of product quality and perceived product quality are reviewed to explain different dimens...
A comparison of data mining methods for prediction and classification types of quality problems Anaklı, Zeynep; Anaklı, Zeynep; Department of Industrial Engineering (2009) In this study, an Analytic Network Process (ANP) and Preference Ranking Organization MeTHod for Enrichment Evaluations (PROMETHEE) based approach is developed and used to compare overall performance of some commonly used classification and prediction data mining methods on quality improvement data, according to several decision criteria. Classification and prediction data mining (DM) methods are frequently used in many areas including quality improvement. Previous studies on comparison of performance of the...
