Within the SMEs, developing relationships with suppliers is a major concern of procurement specialists. Their selection is considered a delicate problem for the organizations that want a strategic position in the market due to the direct impact on the cash flow and profitability. The process of evaluating and selecting suppliers is rather complicated due to a range of influencing factors, the combination of quantitative and qualitative selection criteria, the number and diversity of suppliers along the supply chain, etc. Managing the green supply chain means managing the flows of funds, information and products between them, in all its stages, in order to find the right balance between the ecological and economic aspects.
