摘要:The paper presents the role and the importance of logistics for products and services in order to obtain the competitive advantage. After a short presentation of logistics evolution, we move on to defining the logistics concept, respectively integrated logistics. The analysis of the logistics activities is based on the total cost concept and it has as a purpose the efficient and effective management of the physical flows of raw materials, materials and finite products, and of the international flows. The competitive advantage is ensured through the harmonization of the logistics function with the other functions of the company and through the integration of the logistics chain of all upstream and downstream organizations in order to ensure a high level of consumer service at economical costs under the form of supply chain management. In the end we present the main tendencies in the evolution of logistics in the Romanian firms under the circumstances of the increase of their international dimension.
