An evaluation of order-picking tour efficiency in two-block warehouses

Ozturkoglu, O.; Hoser, D. (Operations and Supply Chain Management, 2019)

This study investigates the effects of critical operational and strategical decisions in order-picking warehouses on order pickers' tour lengths. For this study, one of the most-commonly applied layouts in practice, called ...

Aisle designs in unit-load warehouses with different flow policies of multiple pickup and deposit points

Kocaman, Y.; Ozturkoglu, O.; Gumusoglu, S. (Central European Journal of Operations Research, 2019)

This study focuses on investigating the best layouts of a unit-load warehouse for single-command operation. We propose a model for unit-load warehouses having a single cross aisle and multiple pickup & deposit (P&D) points ...

A new layout problem for order-picking warehouses

Ozturkoglu, O.; Magara, A. (Proceedings of the International Conference on Industrial Engineering and Operations Management, 2019)

Recent studies of warehouse layout designs show that the travel distance for order-picking operations can be reduced by changing the angle of the cross aisles in the traditional warehouse layout. Thus, in this study, a new ...

Propose a Polynomial Time Algorithm for Total Completion Time Objective

Ozturkoglu, Y.; Ozturkoglu, O. (INT JOURNAL MATHEMATICAL ENGINEERING & MANAGEMENT SCIENCES-IJMEMS, 2021-06)

In this study, we integrate deteriorate jobs with repair&maintenance activity on a single machine scheduling subject to total completion time. This work has more than one motivation. First, jobs are assigned to machines ...

The Effects Of Manual Material Handling Equipment On Loading And Unloading Time Of A Case On A Pallet

Ozturkoglu, O. (2016)

In this study, we mainly investigate the effect of usage of a raisable Turkishntable as a material handling equipment on loading and unloading time to handle a box on a pallet. For this, we compared expected time to pick ...

Identical Parallel Machine Scheduling With Nonlinear Deterioration And Multiple Rate Modifying Activities

Ozturkoglu, O. (2017)

This study focuses on identical parallel machine scheduling of jobs with deteriorating processing times and rate-modifying activities. We consider nonlinearly increasing processing times of jobs based on their position ...

Kara Yolu Navlun Fiyatlarinin Belirlenmesi Için Yeni Bir Yaklaşim Ve Uygulama

Dizbay, I.E.; Gumusoglu, S.; Ozturkoglu, O. (2020)

Nakliye firmaları uzmanlaştıkları alanlara göre belirli bölgelere daha sık, daha yüksek miktarlarda taşıma gerçekleştirmektedirler. Nakliyeciler sıklıkla uğradıkları bölgelerde, araçlara geri dönüş yükü ...

Aşı Tedarik Zinciri Süreçleri: Karşılaşılan Sorunlar Ve Dijital Çözümler

Dizbay, I.E.; Ozturkoglu, O. (2021)

Salgın hastalıkların yayılımını Englishelleme yöntemlerinin en önemlilerinden biri aşılama yöntemidir. Aşılama yöntemi kullanılarak salgın hastalıkların tamamen yok edilmesimümkün olabilmektedir.Ancak hastalık veya ...

Yeni Bir Depo Tasarım Problemi Ve Polinomsal Zamanlı Optimal Sipariş Toplama Algoritması Önerisi

Ozturkoglu, O.; Hoser, D. (2018)

Bu çalışmada, depolardaki ana koridorların yerleşim düzeni ile ilgili olarak yeni bir tasarım problemi tanımlanmıştır. Bu problemde, depolarda sıklıkla kullanılan doğrusal düz orta ana koridor kesikli olarak, örneğin mal ...
