Purpose: To conduct an analytical study of the current state of Turkmenistan transport and logistics system, taking into account the geopolitical situation, including the questions of the development of logistics infrastructure and international transport corridors and ongoing large-scale transport-logistics projects. Methods: The method of analytical review of the state of transport and logistics system of the Republic of Turkmenistan is applied. Results: The characterization of the development of transport modes, of established trade-economic and transport links is given. The analysis of existing logistics infrastructure is carried out. The key features of Turkmenistan transport and logistics system are established. Promising target development tracks are formulated. Practical significance: An analytical review of the current state, trends and prospects for the development of Turkmenistan transport and logistics system has been carried out. It has been established that Turkmen transport and logistics system works with cargo flows through almost all transport modes. The country develops modern logistics tools, building modern competitive transport macrostructure, which includes the system of international transport corridors and multimodal type logistics centers, and pursues policy of open transport-logistic space and integration. Based on the study results, the key distinctive features of transport-logistic system existing image were formulated, SWOT analysis of transport-logistics system features was performed, as well as promising tracks of the system development were defined.

Purpose: To develop a mathematical model for calculating twenty-foot equivalent in container trains on the platform given model, to formulate a calculation method in twenty-foot equivalent (TFE) in container trains, to designate a target function in finding optimal filling capacity of fitting platform. Methods: Mathematical calculations were applied using Pascal software environment in terms of automating calculation of fitting platform capacity. Research results: During the calculations, mathematical model design was carried out as well as the study of parameters such as a container mass, size and model was done. Using the analysis of container train load, a target function for the search of fitting platform optimal filling capacity was identified. Practical significance: Review of calculation process for twenty-foot equivalent was carried out by station employees. It is established that as a new element in paperwork chain there should be considered automatic calculation of TFE in container trains, namely, TFE automatic reporting based on the obtained values for TFE in terms of filling in a general form act and a cumulative statement. The description of TFE calculation stages for a one container of 22G1 size on platform given type is demonstrated. Based on the study results, software product in Pascal environment for the calculation of a one container capacity into TFE is proposed.
