چکیده

This paper addresses a multi-period, multi-vehicle, location routing problem (LRP) where capacitated vehicles distribute hazardous materials from multiple plants to multiple retailers to meet the given demand of hazardous materials. Also, the risk of location and routing, cost of transporting hazardous materials from plants to retailers is considered. A series of middle nodes is considered which if needed to reduce the risk and costs, use them. CO2 emissions from transport activities in a supply chain are key players in global warming. Routing decisions can help in the reduction of CO2 emissions if these emissions are taken into account by the decision makers. The proposed framework is a multi—objective deterministic programming model. The first objective function aims to minimize the expected value of the supply chain costs including CO2 emissions produced by the vehicles. The second objective function aims to minimize the total risk of establishing plants and risk of transportation. The demands associated with retailers is assumed to be time varying and deterministic. The proposed model is a mixed-integer linear program that was coded and solved in GAMS. We provide a numerical study showing the applicability of the model.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
