ARAŞTIRMA GELİŞTİRME HARCAMALARININ G-7 ÜLKELERİNİN GELİŞMİŞLİK DÜZEYİNE ETKİLERİNİN İNCELENMESİ: YENİ BİR KARAR MODELİ
(2022) Çanakçıoğlu, Mustafa; Görçün, Ömer Faruk; Görçün, Ömer Faruk; Küçükönder, Hande
Günümüzde ülkelerin gelişmişlik düzeyinin önde gelen göstergelerinden biri de inovasyon yeteneği yani yeni ürün geliştirme yeteneğidir. Böylece ülkeler küresel rekabet ortamında katma değeri ve toplumsal refahlarını artırmak için ürün ve teknoloji geliştirme yeteneklerini hızla geliştirmeye yönelmişlerdir. Ancak araştırma ve geliştirme (Ar-Ge) için yapılan harcamalar her zaman katma değer yaratan yeni ürünlerin üretilmesiyle sonuçlanamamaktadır. Maliyetin yüksek olmasına neden olduğu için özel sektör yatırım ve Ar-Ge harcamalarında çekingen davranabilmekte ve doğrudan görece düşük katma değere sahip kısa vadeli yatırımlar ve Ar-Ge harcamaları yapmaktadır. Bu koşullar altında ülkelerin yeni ve teknolojik ürünler üretebilmeleri, Ar-Ge maliyetlerini büyük ölçüde kamu otoritelerinin üstlenmesine bağlıdır. Ancak Ar-Ge harcamaları kamu bütçesine ağır bir yük getirmekte ve çok büyük miktarda kamu kaynağının harcanmasına neden olabilmektedir. Bu açıdan Ar-Ge harcamalarının ülkelerin bu konudaki hedeflerine olan etkilerinin gerçekçi bir bakış açısıyla ölçülmesi, analiz edilmesi ve değerlendirilmesi gerekmektedir. Bu nedenle, ülkelerin yeni ve teknolojik ürün üretme kabiliyetine ilişkin performanslarını kamu kaynak kullanımını dikkate alarak ölçmek için pratik, uygulanabilir ve iyi sonuçlar verebilecek bir metodolojik çerçeveye ihtiyaç duyulmaktadır. Ayrıca yazarlar tarafından yapılan kapsamlı bir ön araştırma sonucunda mevcut literatürde ciddi ve önemli boşluklar tespit edilmiştir. İlk olarak, yazarların bilgisine göre, ülkelerin Ar-Ge performanslarını ele alan çalışmaların sayısı dışında karşılaştırmalı analiz sağlayan bir çalışma yok denecek kadar azdır. Yakın çalışmaların çoğu bazı sınırlamaları ve yapısal sorunları olmasına rağmen Veri Zarflama yöntemi (VZA) yaklaşımını uygulamayı tercih etti ve sağlam bir metodolojik çerçeve önermediler. Ayrıca daha önce yapılan bu çalışmalarda kriterlerin nasıl belirlendiği hakkında bir bilgi bulunmamaktadır. Uygulanan model ve kriterlerin güvenilirliği konusunda şüphe uyandırmakta ve güvenilir bir değerlendirme ortamı sağlamamaktadır. Çalışmanın temel motivasyonu, bu boşlukları ve gereksinimleri göz önünde bulundurarak objektif ve sağlam bir entegre karar verme modeli önermektir. Ayrıca kamu otoritelerinde, kurumlarda ve bireylerde güçlü bir motivasyon vardır. Mevcut makale, kamu otoriteleri tarafından Ar-Ge harcamaları için elde edilen çıktıları analiz etmek için matematiksel bir operatör yardımıyla Entropi ve CRITIC teknikleri ile birleştirilmiş ağırlıklandırma sistemine dayalı EATWOS tekniğinin kullanılmasını önermektedir. Önerilen çerçeve, ülkelerin Ar-Ge harcamalarının ülkelerin yenilikçilik yeteneği üzerindeki etkilerine ilişkin performanslarını değerlendirmek için uygulandı ve önerilen modelin ve sonuçlarının geçerliliğini ve uygulanabilirliğini test etmek için kapsamlı bir duyarlılık analizi yapıldı. Duyarlılık analizinin sonuçları, önerilen Çok Kriterli Karar Verme (ÇKKV) çerçevesinin geçerliliğini ve uygulanabilirliğini onaylar.

Evaluation of Third-Party Logistics Service Providers for Car Manufacturing Firms Using a Novel Integrated Grey Lopcow-Psi Model
(Pergamon-elsevier Science Ltd, 2024) Ulutas, Alptekin; Görçün, Ömer Faruk; Topal, Ayse; Gorcun, Omer Faruk; Ecer, Fatih
Automotive businesses often delegate logistical tasks to third-party logistics (3PLs) service providers to acquire a competitive edge in the dynamic market. Nevertheless, selecting the most suitable third-party logistics (3PL) partner is a multifaceted undertaking that needs careful evaluation of several criteria and alternatives. This research aims to introduce an integrated grey Multiple Criteria Decision Making (MCDM) framework for automotive businesses to deal with the multidimensional 3PL selection decision problem. This framework incorporates an enhanced Preference Selection Index (PSI), Logarithmic Percentage Change-driven Objective Weighting (LOPCOW), and Mixed Aggregation by Comprehensive Normalization Technique (MACONT). The LOPCOW-G and grey PSI (PSI-G) methods extract the criterion weights, whereas the MACONT-G method ranks the alternatives. The suggested framework's practicality is shown by conducting a case study about evaluating and selecting a third-party logistics (3PLs) provider. The findings indicate that the parameters of significant importance are "skilled workforce (0.0977)," "financial strength (0.0901)," and "IT-IS competence (0.0839)." Furthermore, TPL4 has been recognized as the most optimum option with a value of 0.4797. The MACONT-G model is as well compared against other grey MCDM techniques to assess the validity of the proposed model. The Pearson correlation coefficient between MACONT-G and the other models based on grey sets is 0.958, suggesting a significant and positive link. Furthermore, it is worth noting that a sensitivity analysis has been conducted to validate the accuracy and reliability of the created framework. In conclusion, this study has identified managerial and policy implications that might assist policymakers and executives in effectively evaluating 3PL providers.
Ağır Treylerlerin Seçiminin Ahp Yöntemi ile Değerlendirilmesi
(Düzce Üniversitesi Fen Bilimleri Enstitüsü, 2019) Görçün, Ömer Faruk; Görçün, Ömer Faruk
Ağır ve havaleli yüklerin taşınması süreçlerini de kapsayan proje lojistiği son derece hassas operasyonlardan oluşan lojistik bir faaliyettir. Treyler seçimine ilişkin kriterlerin ve karar noktalarının çok sayıda olması treyler seçimini son derece zorlaştırmaktadır. Seçime ilişkin süreçler etki eden faktörlerin ve değişkenlerin çok sayıda olması treyler seçimine ilişkin süreçlerde çok kriterli karar alma metodolojilerinin uygulanmasını iyi bir seçenek haline getirebilmektedir. Bu çalışmada çok kriterli karar alma yöntemlerinden birisi olan Analitik Hiyerarşi Prosesi kullanılmıştır. Bu çalışma, proje lojistiği ve ağır taşımacılık faaliyetlerinde kullanılacak treylerlerin seçimi ile ilgili olarak karar vericilerin hangi kriterlere daha fazla önem verdiklerinin yanı sıra, karar alternatifleri arasından yapacakları tercihlerin daha uygun ve rasyonel bir tercih olabileceğini sayısal bir perspektife tanımlamaya çalışmaktadır

Foreign Market Selection of Suppliers Through a Novel Ref-Sort Technique
(Emerald Publishing, 2023) Aytekin,A.; Görçün, Ömer Faruk; Görçün,Ö.F.; Ecer,F.; Pamucar,D.; Karamaşa,Ç.
Purpose: The present study aims to provide a practical and robust assessment technique for assessing countries' investability in global supply chains to practitioners. Thus, the proposed approach can help decision-makers evaluate and select appropriate countries in the expansion process of the global supply chains and reduce risks concerning country (market) selection. Design/methodology/approach: The present study proposes a novel decision-making approach, namely the REF-Sort technique. The proposed approach has many valuable contributions to the literature. First, it has an efficient basic algorithm and can be applied to solve highly complicated decision-making problems without requiring advanced mathematical knowledge. Besides, some characteristics differentiate REF-Sort apart from other techniques. REF-Sort employs the value or value range that reflects the most typical characteristic of the relevant class in assignment processes. The reference values in REF-Sort and center profiles are similar in this regard. On the other hand, class references can be defined as ranges in REF-Sort. Secondary values, called successors, can also be employed to assign a value to the appropriate class. REF-Sort can also determine the reference and successor values/ranges independently of the decision matrix. In addition, the proposed model is a maximally stable and consistent decision-making tool, as it is resistant to the rank reversal problem. Findings: The current papers' findings indicate that countries have different features concerning investment. Hence, the current paper pointed out that only 22% of the 95 countries are investable, whereas 19% are risky. Thus, decision-makers should make detailed evaluations using robust, powerful, and practical decision-making tools to make more reasonable and logical decisions concerning country selection. Originality/value: The current paper proposes a novel decision-making approach to evaluate. According to the authors' information, the proposed model has been applied to evaluate investable countries for the global supply chains for the first time. © 2022, Emerald Publishing Limited.

The Selection of Appropriate Ro-Ro Vessel in the Second-Hand Market Using the Waspas' Bonferroni Approach in Type 2 Neutrosophic Fuzzy Environment
(Pergamon-Elsevier Science Ltd, 2023) Gorcun, Omer Faruk; Görçün, Ömer Faruk; Pamucar, Dragan; Krishankumar, Raghunathan; Kucukonder, Hande
The second-hand vessel market has quite different dynamics than the market of the new-building vessel, and highly complicated and conflicting criteria and many uncertainties affect the ship selection process. Therefore, it is required to use a robust mathematical model to solve these kinds of decision-making problems. For this purpose, this paper presents an extended version of WASPAS (Weighted Aggregated Sum Product ASsessment) techniques with the help of T2NN based on the Bonferroni function (T2NN WASPAS'B). The three main focal points of the proposed approach are (i) setting the influential criteria to select the appropriate Ro-Ro vessel in the second-hand vessel market; and (ii) presenting a flexible group decision-making approach, which is proper to real decision-making problems. (iii) detecting the interrelations among criteria and eliminating the negative impacts of undesirable and excessive values in input variables on the results. Practical use of the proposed approach is demonstrated to select the appropriate Ro-Ro vessel in the second-hand market. The analysis results show that the most effective and determinative factor is Trailer Lane length, and the most effective alternative is GREIFSWALD. Besides, the consistency and validity of the obtained results have been verified with the help of a stability and robustness check. The results prove that the proposed novel T2NN WASPAS'B model is robust, powerful, and reliable for making rational and realistic decisions.

An Integrated Mcdm Approach for Evaluating the Ro-Ro Marine Port Selection Process: a Case Study in Black Sea Region
(Routledge, 2021) Görçün, Ömer Faruk; Görçün, Ömer Faruk; Küçükönder, Hande
Selection of the appropriate Roll-on Roll-off (Ro-Ro) port is one of the crucial tasks for the maritime industry. Because there are many factors affecting the selection process, this selection process is essentially a multi-criteria decision-making problem. This paper proposes a integrated approach consisting of the CRITIC (Criteria Importance Through Intercriteria Correlation) technique and the EDAS (Evaluation based on Distance from Average Solution) method to evaluate the Ro-Ro marine ports selection. The obtained results by using the proposed model have been verified carrying out a comprehensive sensitivity analysis. In accordance with this purpose, 10 different scenarios were established and five MCDM methods were applied to make a comparison. Results obtained using the suggested model were verified in dynamic conditions. The main purpose of this implementation is to determine whether any change in the obtained results for each determined scenario. Carried out sensitivity analysis shows that the suggested hybrid MCDM model consisting of CRITIC and EDAS techniques has validity and the obtained results are accurate and realistic. When the results of the sensitivity analysis are reviewed, it can be seen that the P1 option is the best alternative for all scenarios.

A Novel Performance Evaluation Technique Based on Integrated Weighting Approach: A Case Study in the Field of Sport Management
(Growing Science, 2021) Gorcun, Omer Faruk; Görçün, Ömer Faruk; Kucukonder, Hande
It is a fact accepted by everybody that football is the most popular sport around the world. The result of a derby match may be very important for millions of people. Even the time seems to stop on a match day for so many people. Show and entertainment are the most important aspects of football. If soccer players have a high performance, a match may provide pleasure and excitement to audiences. Briefly, the performance and quality of soccer players are the key factors, which draw audiences. Goalkeepers are also one of the important components of football like other players playing different positions such as strikers, mid-fielders, and defenders. Moreover, a goalkeeper can affect the result of a match positively or negatively. Therefore, with the help of a mathematical approach as the methodological framework, it can be seen that the examination of the performance of goalkeepers can be beneficial for decision-makers performing in the fields of sport and the future studies. The current paper proposes an improved integrated multi-criteria decision-making approach to evaluate the selection of goalkeepers; and this model can be applied for goalkeeper's performance analysis. The proposed model combines the weights of criteria calculated with the help of both the CRITIC and the PSI techniques by applying the weight aggregation operator. It also ranks the decision alternatives by implementing the WASPAS technique based on the final criteria weights obtained by using the weight aggregation operator. In addition, a comprehensive sensitivity analysis consisting of three stages was performed to verify the validation of the suggested hybrid model. It has been observed that All has remained the best option for all scenarios. As a result, the results of the sensitivity analysis prove that the proposed hybrid MCDM technique is a very useful, strong and applicable approach. Also, the results obtained by applying the proposed model are accurate, realistic, and reasonable according to the results of the validation test.

Sustainable Aviation Fuel Supplier Evaluation for Airlines Through Lopcow and Marcos Approaches With Interval-Valued Fuzzy Neutrosophic Information
(Elsevier Sci Ltd, 2025) Görçün, Ömer Faruk; Tanriverdi, Gokhan; Yasar, Mehmet; Gorcun, Omer Faruk
In line with the 2050 net zero emission target, sustainable aviation fuel (SAF) is recognized as one of the most effective decarbonization solutions for the aviation industry, which has been identified among the critical areas for mitigating climate change. However, although sustainability issues and decarbonization have attracted scholars' attention in various terms for the airline industry, we identified some significant theoretical and managerial gaps as follows: (i) the number of studies evaluating sustainable suppliers by airlines via multicriteria decision-making (MCDM) approaches are very few, (ii) the extant literature has no paper addressing airlines' SAF supplier selection process, and (iii) no widely established criteria set in the literature to evaluate the SAF suppliers for airlines. We propose a novel model for the decision-making process of airlines' sustainable SAF supplier selection, including 39 criteria from 5 aspects considering the triple bottom of sustainability. The proposed model involves the combination of the logarithmic percentage change-driven objective weighting (LOPCOW) and measurement alternatives and ranking according to the compromise solution (MARCOS) approaches' extended forms based on the interval-valued fuzzy neutrosophic numbers (IVFNN). A comprehensive sensitivity and comparison control is further exploited to display the developed framework's robustness and practicality. Our results suggest that airlines prioritize the green initiatives of SAF suppliers over the economic aspect in the process of sustainable SAF supplier selection. We provide some managerial and policy insights for practitioners and policy-makers in the airline industry and some directions for further research.
