The multidimensionality of transformations that take place, the diversity of destabilizing factors in the environment reduce reliability, sustainability, efficiency of both logistics processes and the entire production and economic activity, and they need their modern economic reflection. The successful activity in the unstable economic environment is impossible without proper strategic analysis and the formation of the effective management system that requires the search for new techniques, the development of logistics-oriented concepts, management approaches to logistics processes that can ensure the goals achievement under the continuous systemic development and disturbance flow. The goal of the research is to improve the technique and develop a management model for logistics processes, considering the effect of the disturbance flow. In accordance with the goal, it is necessary to solve the following scientific problems: to reveal the patterns of logistics processes for the formation of a signal system on management points within the framework of management structures; to develop components of the management technique for logistics processes, taking into account the disturbance flow; to systematize and supplement the principles of logistics processes for the formation of the rational totality of components in the management technique. Thus, the implementation of the proposed management technique for logistics processes will lead to the formation of optimal management impacts within each element, subsystem and the entire structure of the supply chain, ensuring the sustainable development vector at each time period and achieving the goals set under the influence of the disturbance flow, adaptability, flexibility and efficiency of processes.

JSC "Russian Railways" is one of the world's largest companies in the railway market. It ensures the safety and accessibility of transport in Russia, reduces the transport load on its economy. JSC "Russian Railways" is a company founded by the Russian Federation. In the conditions of the global financial crisis and limited budget resources, the search for ways to reduce the costs of its operation comes to the forefront. In the supply, there is a significant potential for increasing the efficiency of any company's activity by saving on purchases in the case of choosing a key supplier that meets all customer's criteria. In turn, the growing relevance in modern conditions is acquired by strategically supplier-oriented management in the process of meeting the needs and requirements of companies. In this regard, the article substantiates the need for strategically supplier-oriented management of commodity and material values in supply chains, systematizes supplier management strategies. The experience of procurement and selection of suppliers of goods, works and services for the needs of JSC "Russian Railways" was studied, a methodology was proposed for ranking criteria for the selection of products and suppliers in order of the decreasing significance value, allowing to expand the method of rating the existing and potential sources of supply.
