Abstract

Considering the limited natural resources, increased consumption level of the world becomes an important problem for the human beings. This fact enforces the governments to make some regulations for the environment. Also, increased consumer consciousness puts a pressure on the companies for being more environmentally friendly. Companies are not only responsible for their own production environment, but also responsible for their suppliers. Hence, the supplier selection and order allocation processes have to be greener. For this purpose, in this study a multi-objective supplier selection and order allocation model is proposed for green supply chains regarding multi-item and multi-supplier case. So as to validate the proposed methodology including three stages, a numerical example is provided by inspiring from the real applications in Turkey.
