A Multiobjective Multiproduct Mathematical Modeling for Green Supply Chain considering Location-Routing Decisions

Global warming and environmental pollution are concepts that more or less encountered in the news newspapers today. Protecting environment is crucial to survival of humanity many plant animal species inhabit planet. Lack control greenhouse gases can increase average surface temperature lead floods serious damage near future. On other hand, overproduction plastics by factories destruction food cycles on Earth. In this study, order sustainability integrate issues supply chain network design decisions, a multiobjective optimization model presented, which two-level routing location problem optimizes economic goals. The first level decisions related selection operating facilities from set potential (manufacturers distribution centers), second determining number products centers retailers manufacturers centers. objective function also minimization type, minimizing fixed variable costs, effects whole chain, includes reducing costs gas carbon emissions.
