An Environmentally Conscious Multi-Objective Weber Problem for Green Location and Distribution Planning: A Fuzzy Weighted Additive Approach

In this study, a multi-objective Weber (p-median) problem is treated in order to determine the location of the warehouses to be opened and the distribution plans of products. The company carries out the distribution with three types of vehicles differing in unit transportation cost, carbon emission and velocity. Three conflicting objectives are aimed to be minimized, i.e.; the demand weighted total transportation cost, the total delivery time and the total carbon. We adopted a fuzzy weighted additive approach to deal with the multi-objective optimization function, in which the weights of each individual objective function are determined by Analytic Hierarchy Process.

Yeşil Alan ve Dağıtım Planlaması için Çevreye Duyarlı Çok Amaçlı Bir Weber Problemi: Ağırlıklandırılmış Bulanık Toplama Yöntemi

Bu çalışmada, açılacak depoların konumunu ve ürünlerin dağıtım planlarını belirlemek amacıyla çok amaçlı bir Weber (p-medyan) problemi ele alınmıştır. Modelde dağıtım, birim taşıma maliyeti, karbon emisyonu ve hızları farklı olan üç tip araç ile yapılmaktadır. Talep ağırlıklı toplam ulaşım maliyeti, toplam teslimat süresi ve toplam karbon emisyonu gibi birbirleriyle çelişen 3 farklı amacın aynı anda enküçüklenmesi hedeflenmiştir. Amaçların ağırlıkları Analitik Hiyerarşi Süreci ile belirlenmiş ve çok amaçlı optimizasyon modeli, ağırlıklandırılmış bulanık toplama yöntemi ile çözülmüştür.
