“…Antmen and Erik (2019) concluded that the current profitability of the business increased approximately thirty-seven times by using the constraints theory and break-even analysis together in their study. Akçimen and Antmen (2019) concluded in their study that the production process created according to the constraints theory in a manufacturing enterprise operating in the metal sector can increase the profitability of the enterprise.…”

With the effect of globalization, businesses need to survive by becoming resistant to competition. Traditional costing methods have been insufficient in the face of needs of businesses to increase their profitability. The purpose of the constraints theory that emerged for these reasons, is to identify and eliminate the constraints that will prevent businesses from operating efficiently. In this context, the theory of constraints is discussed and the basic principles of this theory are emphasized in the study. In this study, it is aimed to determine the optimum production amount by using the constraints theory. Thus, the current profitability of the business is observed after the constraints theory is applied. In practice, the production process of a wine producing enterprise has been examined and analyzed with the basic principles of constraints theory. As a result of the study, it was determined that the optimum product mix of the enterprise is 3000 bottles of white and 836 bottles of red wine according to the constraints theory. While the company made a profit of 93.736 TL with this production method, it was determined that the profitability of the enterprise increased according to the traditional approach.

“…It has been seen that studies in the literature about the TOC are conceptual, the application of TOC principles to different theoretical problems, the comparison of TOC philosophy with different systems and TOC applications (Rahman, 1998). The TOC has been applied to many fields; the manufacturing sector (Ünal, Tanış & Küçüksavaş, 2005;Demircioğlu & Akkaya, 2016;Wolniak, Skotnicka-Zasadzien, & Zasadzien, 2018;Urban & Rogowska, 2018;Rojas, Jurado, & Londono, 2018;Sorkun, 2018;Urban, 2019;Garza, et al, 2019;Akçimen & Antmen, 2019;Aiastui, Perez de Eulate, & Guisasola, 2020;Al-Fasfus, Hamza, & Elkotayni, 2020;Karakoç & Şık, 2021;Mahdi, Abboud & Hussain, 2021), the service sector (Taştan & Demircioğlu, 2015;Akbulut & Ertan, 2015;Ayanoğlu & Şakar, 2015;Yükçü & Yüksel, 2015;Escobar, Vega, & Zamora, 2016;Grida & Zeid, 2019), supply chains (Harish, 2019;Kelly & Germain, 2020;Huang, Lu & Dang, 2021), project management (Mishra, 2020;Sarkar, Jha & Patel, 2021), product mix decisions (Ünal et al, 2005;Kaygusuz, 2005;Mehdizadeh & Jalili, 2018) and human resources management (Tekin & Şahin, 2014;Alghaithi & Sartawi, 2020). 6σ is a systematic approach that aims to increase business profitability, performance, production and customer satisfaction, as well as to reduce the operational costs of the business.…”

Businesses apply many management philosophies aiming to manage processes effectively, eliminate bottlenecks and improve their process performance. The most important of these philosophies are the Theory of Constraints and the Six Sigma. These are used separately in process improvement and performance enhancement in many businesses. Recently, an integration model approach of two philosophies has been examined in the literature in an effort to reduce their weaknesses and increase their strong effects. In the literature, three different approaches are identified for the integration model of Theory of Constraints and Six Sigma. In this study, the integration model of Jin, Abdul-Razzak, Elkassabgi, Zhou, & Herrera, ( 2009) was applied in an industrial enterprise in order to identify and eliminate the root causes of the decline in sales figures. It has been revealed that the integration model can help to identify and eliminate these root causes and how it benefits the business. As a result of the application, an improvement in production cost by 1.56% and 3.55% and an increase in σ value from 1.4 to 2.3 were determined. With this model, constraints in the production process were determined, managed and eliminated.

“…Özellikle kalabalık ve sanayileşmiş şehirlerde sanayinin su kullanımı en yüksek seviyededir. Zaman ilerledikçe, teknoloji geliştikçe; müşteri ihtiyaç ve beklentileri artmakta dolayısı ile yöneticilerin de istekleri değişmektedir (Akçimen & Antmen, 2019). Bu da daha fazla suyun kullanımına yol açabilmektedir.…”

üzere 3 adet meteoroloji gözlem istasyonunun aylık ortalama yağış, aylık ortalama sıcaklık, aylık ortalama nispi nem ve aylık toplam güneşlenme süresi parametreleri kullanılarak kuraklık analizi gerçekleştirilmiştir. Her istasyonun tecrübe ettiği 7 farklı kuraklık sınıfının görülme yüzdeleri bulunmuştur. Sonuçlara göre bölgenin tamamının çoğunlukla çöl iklimine sahip olduğu gözlemlenmiştir. Oransal olarak çöl ikliminin en fazla yaşandığı istasyon Şanlıurfa olarak bulunmuştur. Aylık Aydeniz Metodu ile elde edilen ve gözlenmiş değerler olarak kabul edilen kuraklık katsayısı değerleri, Bulanık Mantık Yaklaşımı'nda 85 adet kural tabanı oluşturularak tahmin edilmeye çalışılmıştır. Tahmin yüzdesinin en yüksek olduğu il %87.5'lik doğru tahmin etme oranıyla Şanlıurfa istasyonudur. Ortalama doğru tahmin etme oranı %83'ün üzerindedir. Böylece, bölgede kuraklık analizinde kullanılan yöntemlerin karar vericilere su kaynakları planlanmasında yol göstermesi beklenmektedir.
