When increased emissions are combined with a carbon tax or emissions trading system, the result is a supply chain with increased costs attributable to the emission generated on the different parts of supply chain. Most traditional supply chain design models do not take emissions and carbon costs into account. Hence, there is a need to incorporate emission costs into a supply chain optimization model to see how the optimal supply chain configuration may be affected by the additional expenses. This thesis presents a mathematical programming model for the design of green supply chains. The costs of carbon dioxide equivalent emissions were incorporated in the objective function, along with the... 

In recent years, environmental issues has been gaining a great deal of attention in the field of Supply Chain and Supplier Selection. In this research, we first review the current literature and then we try to find the research gap in this area. According to the studies done in this area, no research on supplier selection and optimal order allocation to the suppliers have simultaneously investigated environmental issues, the possibility of storage, green routing of vehicles, purchasing discount, multi-product, and multi-period state in a green supply chain. Therefore, in this study, a multi-objective mathematical model is proposed for supplier selection and optimal order allocation in a... 

Network design is one of the major strategic decisions of a supply chain which leads to the whole sustainability of the chain. Besides, due to an increase in carbon dioxide emissions and its harmful effects, recently there has been an growing interest in green supply chain network design. In this thesis, a mixed integer linear programming is developed to formulate a closed-loop supply chain with forward and reverse logistics. Moreover, social cost rate of carbon dioxide is used to consider environmental impact. Considering uncertainty in closed-loop supply chains is crucial. To do so, three robust optimization methods including Soyster, Ben-tal and Nemirovski and Bertsimas and Sim approaches... 

Designing a supply chain of a network is the most important strategic decisions that contribute to the overall stability of it. One of the most sustainable competitive advantage for countries is to make the supply chain activities more efficient and effective. One of the major activities that could be saving a lot on costs, is the logistics activities. Forward and reverse logistics to design independently and asynchronously could provide sub-optimality. Therefore, many companies have been increasingly integrated into the supply chain and logistics networks. Furthermore, concerns for the environmental issues were lead the companies to the closed-loop supply chain that is provided by... 

Environmental management with emphasis on protecting environment is today one of the most important problems for customers, governments, employees and competitors, and international and global pressures has required organizations to produce environmentally consistent products and services. This challenge has resulted in emergence of a new concept namely green supply change management in the realm of business which is a combination of environmental thinking and supply chain, which will be followed by competitive advantages for firms. This approach has widely attracted the attention of industries, governments and institutions relevant to environment. The aim of this study is to identify main...
