Abstract: Optimization is an iterative search process aimed at finding the best solution value for an objective function that satisfies constraints or bounded conditions in mathematically expressible problems. There are hundreds of books written in this field, and a new book is added to the list everyday. Since optimization is a very large field, each book is written for different disciplines. If you want to work on any subject related to this field, reaching the related book can be complicated and time consuming. The point to be reached in the research is to do an extensive research on the optimization books and to obtain relevant statistics. For this purpose, available optimization books related to the operations research of the last ten years were searched and examined in detail according to their topics. This work is aiming at leading the people who want to study about this topic by searching the literature about the optimization in the field of operations research. Öz: Optimizasyon, matematiksel olarak ifade edilebilen problemlerde, belirli kısıt ya da sınırlandırılmış koşulları sağlayan bir amaç fonksiyonu için en iyi çözüm değerinin bulunmasını amaçlayan iteratif bir arama sürecidir. Bu alanda yazılmış yüzlerce kitap bulunmaktadır ve her geçen gün listeye yeni bir kitap daha eklenmektedir. Optimizasyon çok geniş bir alan olduğundan, her kitap farklı disiplinlere yönelik olarak yazılmaktadır. Bu alanla ilgili herhangi bir konuda çalışılmak istenildiğinde ilgili kitaba ulaşmak karmaşık ve zaman alıcı olabilmektedir. Araştırmada ulaşılmak istenen nokta optimizasyon konusundaki kitaplara ve kitapların içerdikleri konulara ilişkin kapsamlı bir araştırma yapmak ve ilgili istatistiklerin elde edilmesidir. Bu amaçla son 10 yıla ait ulaşılabilen optimizasyon kitapları taranmış ve yöneylem araştırması ile ilgili olanlar detaylı olarak konularına göre incelenmiştir. Bu çalışma, uzun süren bir emeğin ürünüdür ve yöneylem araştırması alanında optimizasyon konusu ile ilgili kitaplara yönelik literatür dökümünü çıkararak, bu konuyla ilgili çalışma yapmak isteyenlere yol göstermeyi amaçlamaktadır.

The fact that the production and consumption amounts are different from each other gives a dynamic feature to the concept of storage. In addition, an effective storage activity hinges upon the selection of the right warehouse location that takes into account capital and labor investments; minimizes the transportation cost and time. The aim of this study is to investigate the preliminary researches in the selection of the warehouse location selection and to present information on which success factors and methods are preferred. Within this scope, many academic studies have been examined by filtering various databases. According to the results of the study, the most used methods in warehouse location selection are multi-criteria decision making methods such as AHP, ANP and TOPSIS; and the most commonly used success factor is determined as the cost-based factors.

Dünya üzerinde üretim ve tüketim miktarlarının birbirlerinden farklı olması depolama kavramına dinamik bir özellik kazandırmaktadır. Ayrıca etkin bir depolama faaliyeti; sermaye ve işçilik yatırımlarını dikkate alacak, taşıma maliyet ve zamanını minimize edecek doğru depo yerinin seçilmesinden geçmektedir. Bu doğrultuda çalışmanın amacı, depo yeri seçiminde yapılmış olan öncül araştırmaların incelenmesi ve depo yer seçiminde hangi başarı faktörleri ve yöntemlerin tercih edildiğine dair bir bilgi sunmaktır. Bu amaç kapsamında çok sayıda akademik çalışma çeşitli veri tabanları süzülerek incelenmiştir. Çalışmanın sonuçlarına göre depo yer seçiminde en fazla kullanılan yöntemler AHP, ANP ve TOPSIS’in başını çektiği Çok Kriterli Karar Verme yöntemleri, en çok kullanılan başarı faktörü ise Maliyet içerikli faktörler olarak belirlenmiştir.

Bu çalışmada, süreç iyileştirme uygulamalarının daha iyi anlaşılabilmesi ve yapılan çalışmaların sistematik olarak sınıflandırılabilmesi için bir literatür araştırması yapılmıştır. Literatür araştırması; İnönü Üniversitesi Kütüphanesi Veri Tabanı, ULAKBİM, DergiPark, Google Akademik, Ulusal Tez Merkezi kapsamında gerçekleştirilmiştir. Aramalarda anahtar kelime olarak “süreç iyileştirme”, “süreç iyileştirme teknikleri”, “process improvement”, “process improvement techniques” kelimeleri kullanılmıştır. Bu çerçevede, 2005-2018 tarihleri arasında yapılan çalışmalardan 177 tanesine ulaşılmış ve ki-kare analizleri yapılarak çeşitli faktörlere göre sınıflandırılmıştır. Sınıflandırmalar sonucunda, çalışmaların çoğunluğunun tanımlayıcı, neden-sonuç modelinde ve nicel araştırma türünde olduğu, ve genel teorik çalışmaların yanı sıra uygulamalı çalışmalarında yapıldığı görülmüştür. En çok uygulama yapılan sektörler otomotiv ve sağlık sektörleri olurken en çok tercih edilen iyileştirme yöntemleri ise akış diyagramı, altı sigma, pareto analizi, balık kılçığı diyagramı, istatistiksel analiz yöntemleri ve histogram olarak belirlenmiştir.

Yöneylem Araştırması tekniklerinin sağlık alanındaki problemlerin çözümünde kullanımının son yıllarda dikkat çekici boyutlara ulaştığı görülmektedir. Bu çalışmada, sağlık sistemlerinde karşılaşılan problemler ele alınmış ve planlama, yönetim ve uygulama başlıkları altında sınıflandırılmıştır. Bu konularda çalışma yapacak araştırmacılara yön göstermesi amacıyla, 2007-2017 yılları arasında yayınlanan çalışmalar, konu başlıklarına göre, çözüm yöntemleri ve gerçek hayat problemleri üzerindeki uygulamaları açısından değerlendirilmiş ve Yöneylem Araştırması’nın bu tür problemlerin çözümünde uygulanabilirliği ortaya koyulmuştur.

Academic literature on six sigma quality improvement approach, the first applications of which were observed in the mid-1980s in manufacturing industry, is examined in this study. All journal articles covered by Science Citation Index are searched with the keyword "six sigma" without any time restriction, and full-texts of almost all the articles found were analyzed in detail. The trends, current situation and historical developments in the literature are shown, and the overall standing of the studies in the academic literature about six sigma is discussed. It is concluded that there is no consensus over the definition and the applications of six sigma. Nevertheless, it is expected that six sigma will maintain its importance in the forthcoming years.

Nowadays, firms incorporate reverse flow to their systems because of some reasons such as economic and ecologic reasons, regulations from government, social responsibilities. These firms face to some problems such as designing efficient reverse logistics network and managing the reverse flow of materials, components or products. A generic reverse logistics network includes collecting the cores from customers, stocking, reprocessing and redistributing activities. In this paper, studies about logistics network design and modeling for product recovery are reviewed, classified and the main characteristics of them are tried to analyze. [ABSTRACT FROM AUTHOR]
