An Integrated AHP-TOPSIS Approach for Terminal Selection Problems in the Logistics Management Perspectives of Marine Container Ports: A Case Study for Turkey’s Container Ports and Terminals
(2018) Görçün, Ömer Faruk
This study focuses on the strategic importance of container port selection with regard to container operator companies, logistics firms and other actors of a supply chain. The main focalpoint of this paper deals with two important questions: how a container port and terminal is selected by logistics and marine container operators and what is the most important factors for decision makers. When an answer is seeking to these questions, initially it should be necessary to determine the selection criteria and decision alternatives in detail. In order to select proper and optimal container port and terminal, the Analytic Hierarchy Process (AHP) theory and Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)method were selected and these methodologies were integrated to solve decision-making problem that related to container port selection. This study consists of five stages. In the first stage, a literature review was made. AHP and TOPSIS methods were defined and their steps of these methodologies were shown in the second stage of this study. In the third stage, numerical analysis was realized by using an integrated AHP-TOPSIS methods as a hybrid method. In the fourth stage, the obtained results were evaluated and depth analysis was made by the member of the board of experts. In the final stage, this study was summarized and final results were shown and the contribution of this hybrid method to the literature concerning with the container port selection process was evaluated. In this study, the board of experts that consisted of seven members was constructed and they are professionals who play an important role in the decision making processes in their companies. Therefore, while the members of the board of experts were selected by the researcher, to be the senior executive or company owner in the field of the maritime transportation sector was determined as the main rule. All selection criteria, decision alternatives and the main goal of this study were determined in the roundtable meetings that realized with together the board of experts. Pairwise comparison questions were prepared by the researcher and were directed to the selected thirty decision makers who work in the field of maritime as the senior executive.

LOJİSTİK MALİYETLER ÇERÇEVESİNDE KARADENİZ LİMANLARININ MULTİMODAL TAŞIMACILIĞA UYGUNLUKLARININ ANALİZİ
(Kenan ÇELİK, 2018) Görçün, Ömer Faruk; Görçün, Özhan
Taşımacılık sektörünün önemi hem Dünya’da hem de Türkiye’de her geçen gün artmaktadır. Küreselleşmenin etkisiyle müşterilerin ürünleri daha hızlı ve eksiksiz bir biçimde talep etmelerine paralel olarak, işletmelerin ve tedarik zincirlerinin de rekabet edebilmek için sahip oldukları lojistik hızları ve operasyonel mükemmeliyeti artırmaları zorunlu hale gelmiştir. Daha da önemlisi, tedarik zincirleri yetersiz kalan uygulamalarını güncellemek ve her zaman rekabette kalmalarına olanak sağlayacak yeni yollar ve yöntemler bulmak zorunda kalmaktadırlar. Bu kapsamda, intermodal taşımacılık yeni bir lojistik uygulama olarak giderek önem kazanmaya başlamıştır. Bunun yanı sıra taşıma türleri ve altyapılar arasında entegrasyon intermodal taşımacılığın etkinliği ve verimliliği açısından son derece önemlidir. Bu çalışmada Karadeniz limanlarının intermodal taşıma sistemine entegrasyonu ve denizyolu taşımacılığı ile diğer taşıma türleri arasında bir koordinasyonun sağlanıp sağlanamayacağı ekonomik faktörler de göz önüne alınarak değerlendirmeye çalışılmıştır. Çalışmada Karadeniz limanları üzerinden gerçekleştirilecek intermodal bağlantılar sayesinde oluşturulacak çok modlu taşıma sistemleri “multimodal” ile tek modlu taşıma sistemlerinin etkinlikleri ve verimlilikleri lojistik maliyetler açısından değerlendirilmiş, bu kapsamda Karadeniz limanlarının intermodal ve kombine taşımacılık sistemlerine uyguluğu gözden geçirilmiştir.

Reduction of energy costs and traffic flow rate in urban logistics process
(Elsevier Science, 2017) Görçün, Ömer Faruk
Energy cost is a phenomenon relating to logistics and transportation activities of logistics operators as well as governments local authorities and citizens. Actually all the logistics parties may be affected by energy costs. At the same time logistics and transportation flow rate is declining continuously. Increases in traffic volume and decreased logistics flow rate cause to decrease in logistics productivity and efficiency in a city. On the other hand changes in these factors cause to increase energy cost. Minimum energy consumption plays an important role for efficient and productive urban logistics operations. Increasing traffic volume and congestion may absorb the energy of cities in addition to that it causes to increase energy requirements of urban areas. According to scientific research a significant correlation can be seen between traffic volume congestion energy cost and using the urban economic resources. This study focus on relations between these factors and it tried to show that ways for reduction of energy cost on optimum traffic volume and traffic flow rate. In addition to that the findings of this study depend on fieldwork related to Istanbul city. (C) 2017 The Authors. Published by Elsevier Ltd.

(Association for Computing Machinery, 2018) Görçün, Ömer Faruk
Project logistics is one of the specific logistics operations. Compared to other logistics operations it needs more efficient planning and engineering applications in each operational process. On the other hand each project logistics operation can be defined as tailor-made operations since it has no similarity with other operations. Consequently each project logistics operation should be planned and carried out according to its own conditions and parameters. This study focuses on the simulation of project logistics operations under the light of computerized applications from start to finish of the logistics operation. In this study transportation operations of 600 tons of autoclave from the Petkim port to the Gördes building site were selected as a case study. © 2018 Association for Computing Machinery.
