The purpose of the article: the development of theoretical and methodological provisions for the implementation of the integration approach in logistics. Methodology of work. The study used methods of generalization, systematization, grouping. Results of work. Modern views on logistics as a scientific field of research, as a concept (view) and as an art of management are generalized. The system of functions and tasks of logistics is presented. The concept of logistics integration has been developed as an inter–organizational and intra–organizational integration of individual logistics operations and logistics functions of participants in the logistics process in order to effectively organize the process of material flow from supplier to end consumer with the lowest total cost. Systematized basic principles of logistics chain management, which include the principle of compliance of demand for supply of logistics services; a clear sequence of implementation of a set of logistics operations; resource, operational and functional consistency of logistics processes; mutual benefit of economic interests of all participants of the logistics chain; complexity of logistics services; synchronicity of logistics processes to ensure predictability of their implementation; optimality of all types of resources for the implementation of logistics processes (material, human, time, information, etc.). The reasons of logistic integration are generalized. Logistics integration drivers have been identified, which are the introduction of software and hardware, high competencies of logistics system management, innovative technologies. Identified levels of logistics integration: the level of logistics operations and the level of logistics functions
