In this paper, a sustainable closed-loop supply chain problem is modelled in conditions of uncertainty. Due to the COVID-19 pandemic situation, designed network seeks deliver medical equipment hospitals on time within defined window prevent overcrowding and virus transmission. order achieve suitable model for designing network, important decisions such as locating potential facilities, optimal ...

Today’s business has inevitably been set in the global supply chain management environment. International transportation has never played such an important role in the global supply chain network, because movement of shipments from one country to another tends to be more frequent than ever before. This paper studies international transportation problems experienced by an international transport...

The aim of this paper is to propose a robust reliable bi-objective supply chain network design (SCND) model that is capable of controlling different kinds of uncertainties, concurrently. In this regard, stochastic bi-level scenario based programming approach which is used to model various scenarios related to strike of disruptions. The well-known method helps to overcome adverse effects of disr...

The ever-increasing concerns of the growth in volume waste tires and new strict government legislations to reduce environmental impact end-of-life (EOL) have increased interest among companies design a sustainable efficient closed-loop supply-chain (CLSC) network. In real world, CLSC network is subject variety uncertainties, such as random fuzzy (epistemic) uncertainties. Designing reliable env...

proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...

In this study, tactical decisions considering the material and financial flows in a supply chain have been made. To achieve these aims and some effective solutions, a multi-objective mathematical model proposed for an integrated supply chain master planning problem. The multi-product, multi-period and capacitated supply chain network has three objective functions. Two first objective functions ...
