Abstract

Highlights: Influence of adding environmental impact to cost when designing networks are sought. We define a biobjective model to calculate the best network in our experiments. Different weights are assigned to environment vs. cost to see its influence. 200 networks were used in the experiments finding influence on warehouses opened. Abstract: The degree of centralization of the logistics network is one of the important strategic decisions to take. This issue has often been studied but mainly from a cost minimization focus. This research studies the influence of incorporating the environmental impact in logistics network design models, comparing the results with those obtained considering cost minimization only. A fuzzy biobjective optimization model is used to carry out a number of experiments. By weighting the relative importance of the two objectives, the differences with respect to the base cost minimization solution can be ascertained. Our results show that in general more material is moved through warehouses when the environmental impact is considered and more decentralized facilities are opened.
