Abstract System problems of complex supply chain security (CSCS) in the area of science intensive production and freight hauling are considered in the article. New approaches in application of adaptive supply chain management methods, risk estimation on the basis of international requirements and standards are stated. The role of international standards in loss control, event control in the transport development strategy of RF until 2030 is noted. Modern trends of transport logistics system development require integration with freight owners and stability and security implementation of transportation of freight processes. In view of European Union experience, areas of using complex supply chain security methodology in the framework of transport system of Russia are validated.
Abstract This article discusses the current state and prospect of vehicle sales and growth trends in the automotive industry in BRICS member countries, which currently is the fifth most dynamic developmental sector in the world economy.

Abstract In the article suggested method of modeling material flow passing in system ?supplier ? transport ? producer ? transport ? consumer? on basis of absorbing Markov chains. The results of application this method to factory of glass industry are given.
Keywords logistics, material flow, absorbing Markov chains.
Abstract New approach to definition of indices of importance and minimal sections of breakdowns (MSB) with help of critical up states (CUS) of system elements is proposed. New methods ()algorithms) of receiving of possible statuses of elements, up states, critical up states of elements, indices of importance of elements and minimal sections of breakdowns of system are proposed. New structured data in the form of vector of efficiency of elements of system and matrix of single systemвЂ™s breakdowns are suggested. Received algorithms are used for analysis and synthesis of informational structures.
