Bir kargo şirketi için süreç iyileştirme çalışmaları

Bu çalışmada, bir kargo şirketinde sistem analizi ve iyileştirme uygulamaları dikkate alınmış ve şirketin mevcut sisteminde bazı sorunlar tespit edilmiştir. Bu çalışma kapsamında, niteliksiz araç tipi kullanımı ve araç içi raf bulunmamasından kaynaklanan verimsiz alan kullanımı, paketleri araca yükleme ve indirme işlemi sırasında oluşan zaman kayıpları ve paket hasarı gibi problemleri çözmek amacıyla çok kriterli karar verme yöntemleri uygulanarak şirket için en uygun araç ve seçilen araca uygun araç içi raf tipi seçimi hedeflenmiştir. Ayrıca, GAMS programı yardımıyla şirket için büyük maliyet oluşturan dağıtım maliyetini en aza indirmek için araç rotalama problemi ele alınmıştır. Talep, taşıt miktarı ve taşıt kapasite kısıtlarına göre bir transfer merkezinden on sekiz şubeye rotalar yeniden oluşturulmuştur. Şirketin sisteminde mevcut olan sorunlar kümesi ile ilgilenerek, daha etkili bir sistem sağlamaya çalışılmıştır

Anahtar Kelimeler:

Sistem Analizi ve İyileştirme, Araç Rotalama Problemi, GAMS, Çok Kriterli Karar Verme

Process improvement applications for a cargo company

In this study, system analysis and improvement applications in a cargo company have been considered and some problems have been detected in the company`s current system. In the content of this study, multi-criteria decision-making methods have been implemented to select a vehicle and intra-vehicle shelf type to solve problems about space usage, time losses and package damage due to incorrect vehicle type and absence of intra-vehicle shelf. Besides, to minimize transportation costs which impose significant expenses to the company, the vehicle routing problem is considered with the help of the GAMS (General Algebraic Modelling System) program. In vehicle routing problem, it is aimed at one transfer center to eighteen branches, under the demand, amount of vehicle and capacity of vehicle constraints. While concerning the set of problems that exist in the company`s current system, it`s attempted to provide a more effective system.
