Construction of a descriptive model of the logistics chain for the delivery of goods in the interaction of rail and sea transport

Objective: To consider the issue of phased modeling of the logistics chain for the delivery of goods using rail and sea transport. To establish the goal and results of each stage of the simulation. To move to the construction of a descriptive model of the process under study. Methods: The analysis of the logistics chain of cargo delivery in multimodal transport, modeling of the logistics chain of cargo delivery with the construction of a descriptive model at the initial stage is applied. Results: A detailed diagram of the modeling stages is presented with the set goals and results of each stage. A fragment of the descriptive model was built at the stage of dispatching cargo traffi c from a railway station. Practical importance: The importance of consistent modeling of the logistic process is shown in compliance with the principles of the adequacy and effi ciency of the model. The importance of routing cargo fl ows to seaports is estimated
