POSSIBILITIES FOR IMPROVING OF SUPPLY CHAIN PERFORMANCE IN THE CONTEXT OF SUSTAINABLE DEVELOPMENT

On estimating dynamic factor demands supported by normalizations and the new economic model imposed by globalization additional costs for research and development have occurred. These additional costs are constantly increasing and present a major challenge for the actors in the supply chain to achieve customer satisfaction. For achieving the objectives, the supply chain is impacted by the reduction of the costs and the productions activities are often restrained to meeting the immediate objectives without any integration with the upstream supply chain. Consequently, if a company wants to maintain balanced sustainable development, a quest towards an efficient supply chain should be based on the purchasing function, with an aim to achieve continuous improvement of margins and regular exchange of knowledge and information with suppliers and actors of the supply chain. This article aims at placing the purchasing functions in the context of the strategic management concerns of the companies, as well as in the operational flows, identifying the stakes of the purchases in the overall performance, and as a result, proposing a model for a sustainable logistic chain management, based on information and management systems external and internal integration.
