Kaos durumu altında hava kargo şirketi seçimi: Bütünleşik Bayesian BWM ve WASPAS çerçevesi

BOZ, Esra | ÇİZMECİOĞLU, Sinan | ÇALIK, Ahmet

Karar problemlerinin sonuçları ve bu sonuçları etkileyen faktörler, herhangi bir kaos durumunun bulunup bulunmamasına göre değişiklik gösterebilmektedir. Kaos durumları altında, karar alıcıların tercihleri için farklı kriterler eklenebilmekte ve kriterlerin önem düzeyleri değişebilmektedir. COVID-19 pandemisi her alanda olduğu gibi havacılık sektörünü de etkilemiş olmasına rağmen hava kargo taşımacılığı bu dönemde güçlü bir performans göstermektedir. Bu noktadan hareketle, bu çalışmada kaos durumlarının hava kargo şirketi seçimine yansıması incelenmektedir. Karar vericilerin, karar problemleri ...Daha fazlası

A Novel Interactive Fuzzy Programming Approach for Optimization of Allied Closed-Loop Supply Chains

ÇALIK, Ahmet | PEHLİVAN, Nimet Yapıcı | PAKSOY, Turan | WEBER, Gerhard Wilhelm

In recent years, the relationship between companies and suppliers has changed with the continuous rise in environmental awareness and customer expectations. In order to fulfill customers’ needs, the actors in a Supply Chain (SC) network sometimes compete and sometimes cooperate with each other. In SC management, both competitive and collaborative strategies have become important and have required different points of view. In a collaborative environment, companies should strive for common targets with mutual relationship. After managers decided to share their resources, some positive effects ha ...Daha fazlası

Lean and Green Supplier Selection Problem: A Novel Multi Objective Linear Programming Model for an Electronics Board Manufacturing Company in Turkey

ÇALIK, Ahmet | PAKSOY, Turan | HUBER, Sandra

Even though various studies are proposed to evaluate and determine the best suppliers, studies generally consider similar factors such as cost, quality, delivery time etc. in the supplier selection problem. Nowadays, some lean and green issues such as on time (JIT) delivery, waste reduction, avoidance and treatment of hazardous materials, energy efficiency, occupational health and safety, corporate social responsibility, etc. started to be addressed together with the supplier selection process. Lean and Green Supply Chain Management (L-GSCM) is a dynamic field for companies to gain advantages ...Daha fazlası

PAKSOY, Turan | ÇALIK, Ahmet | KUMPF, Alexander | WEBER, Gerhard Wilhelm

The dynamics of Supply Chain Management (SCM) have changed over the years; new paradigms are added into the SCM as a response to changes related with increasing environmental concerns and pressures. Therefore, lean and green practices in a company belong to its most important factors to enhance the company’s performance. In this study a new model, inspired by an automotive supply chain, is proposed for lean and green closed-loop supply chain management. In this model, we deal with lean and green drivers to set the objectives of the decision makers (DMs) as follows; (1) Construction: The amount ...Daha fazlası

Multi-level optimization of an automotive closed-loop supply chain network with interactive fuzzy programming approaches

YILDIZBAŞI, Abdullah | ÇALIK, Ahmet | PAKSOY, Turan | ZANJİRANİ FARAHANİ, Reza | WEBER, Gerhard Wilhelm

Closed-Loop Supply Chain (CLSC) management has attained appreciable attention over the last few years. CLSC management allows companies to manage their recovery and recycling activities of end products. Due to the latest developments in the world, producers are responsible for the collection, refurbishing, repairing and disassembly of end products at the end of their lives. This paper develops a mixed-integer CLSC model that is inspired by the automotive industry. In this model, we consider three Decision Makers (DM): Plant, Dismantler Center and Customer. Each DM has individual objectives and ...Daha fazlası

Allied closed-loop supply chain network optimization with interactive fuzzy programming approach

ÇALIK, Ahmet | PEHLİVAN, Nimet Yapıcı | PAKSOY, Turan | KARAOĞLAN, İsmail

The concept of closed-loop supply chain (CLSC) has started to attract growing attention due to the consumer pressures, environmental awareness, and legislations. Managers in many companies have realized that a well-designed supply chain (SC) can improve the companies’ performance in the market. Thus, a lot of companies start to focus on CLSC issues including remanufacturing, refurbishing, recycling, and disposal of end-of-life products. The body of literature on CLSC management has been overwhelmingly dominated by noncooperative studies. In order to fill up this gap in the literature, we deal ...Daha fazlası

YAPICI PEHLİVAN, Nimet | PAKSOY, Turan | ÇALIK, Ahmet

Green supply chain management (GSCM) is described as the combination of environmental thinking and supply chain management (SCM) encompassing product design, material sourcing and selection, manufacturing processes, delivery of the nal product to the consumer, and endof-life management of the product (Srivastava, 2007; Tseng and Chiu, 2013). Environmental sustainability of a supply chain depends on the purchasing strategy of the supply chain members. Most of the supply chain models focus on cost, quality, lead time, carbon emission, etc., issues for supplier selection. Shaw et al. (2012) prese ...Daha fazlası
