Interval Type-2 Fuzzy Analytic Hierarchy Process Application on Warehouse Performance Measurement Criteria Defined

YAŞAR, Esra | ARAS, Nil

Warehouse performance measurement is of great importance for the development of companies. The companies are to measure their current situation in order to attain ability relating to realizing the improvement process. In this measurement phase, they have to decide what is considered and what proportion it is done. In this study, the most effective factors were determined using the interval type-2 fuzzy analytic hierarchy process method for the factor values that are effective in warehouse performance measurement. The reason to use this solution method is that because of having 3 dimensional me ...Daha fazlası

ÇİZMECİOĞLU, Sinan | AKPINAR, Ayhan | ÇALIK, Ahmet

In today’s highly competitive marketplace, continuous improvement efforts are one of the best strategy to improve products, services, or processes. To support continuous improvement, companies continually examine their processes to discover and eliminate problems. The impact of Lean and Green Manufacturing Practices (LGMP) that widely deemed as one of the most disseminated production systems have been showed by several authors. What are the emerging issues in research on lean and green manufacturing practices? What are the most preferred practices in lean and green logistics have on the enviro ...Daha fazlası

Third-Part Logistics (3PL) Provider Assessment by Using Fuzzy AHP-VIKOR Apptoach

ÇALIK, Ahmet | ÇİZMECİOĞLU, Sinan | AKPINAR, Ayhan

Economic contractions, new communication technologies, and new market search have forced companies more outsourcing by shifting its operations geographically to distant countries. Transferring all or part of the logistics activities to the external firm(s) can be defined as outsourcing. Some of the opportunities to add value to companies through outsourcing: supply security, cost reduction, gaining flexibility in the supply chain, shortening average order cycle times, expanding market boundaries. When it is time to select a third-party logistics (3PL) provider for a particular use, companies s ...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

A Two Stage Solution Procedure for Real-Life Location-Routing Problem

YAŞAR, Esra | BOTSALI, Aahmet Reha

Warehouse location selection and vehicle routing are two important problems that are studied in supply chain literature. Although it is possible to solve the classical warehouse location selection problem at the optimal level for most cases, the vehicle routing problem is more difficult to solve. The simplest version of vehicle routing problem is the travelling salesman problem (TSP) which is NP-Hard. Recently, warehouse location selection and vehicle routing problems are analyzed together as an integrated problem referred as location-routing problem. In this study, we analyzed this integrated ...Daha fazlası

Akıllı Çöp Toplama Sistemlerinde Tersine Stokastik Envanter Rotalama Problemi

YAŞAR, Esra | ÖZTÜRK, Gürkan

Günümüzde çöp toplama sistemleri şehircilikte çok önemli bir kavram haline gelmekte ve belediyeler maliyetlerini düşürmek ve insanlara daha iyi hizmet verebilmek için makineler arası iletişim teknolojisini kullanarak akıllı çöp konteyner sistemine geçmektedirler. Makineler arası iletişim teknolojisi sayesinde araçlar yalnızca dolu olan çöp konteynerlarını ziyaret eder, böylece hem personel hem de yol masrafı azaltılmış olur. Bu süreçteki en kritik karar, hangi aracın hangi rota ile hangi konteynerlara gideceğidir. Bu çalışmada bu problem tersine stokastik envanter rotalama problemi olarak ele ...Daha fazlası

An integrated fuzzy AHP/DEA approach for performance evaluation of territorial units in Turkey

ÇALIK, Ahmet | YAPICI PEHLİVAN, Nimet | KAHRAMAN, Cengiz

Due to the differences between regions and sub-regions in the countries, some problems come out especially in economic and social life. The issue of differences of regions has been widely implemented to evaluate the economic performance of Turkey in many disciplines. The objective of this paper is to evaluate the efficiency of 26 sub-regions of NUTS-2 classification using integration Fuzzy Analytic Hierarchy Process (FAHP) with Data Envelopment Analysis (DEA). The integrated FAHP/DEA method comprises two stages. In the first stage, linguistic terms are used to determine the decision makers’ op ...Daha fazlası

Solution of Multi-Objective Optimization Model in FMS Design with Scalarization Methods

YAŞAR, Esra

Multi-objective optimization problems are more encountered in real life than single-objective optimization problems. Therefore, the solution of this multi-objective optimization problems has a critical importance due to its contribution to many areas. The objective function of operation allocation and material handling system selection in Flexible Manufacturing System (FMS) in the literature are created to minimize the costs related to the manufacturing operations, machines set up and material handling operations and to maximize the compatibility of the part types and the material handling equ ...Daha fazlası
