“…In such conditions, train flows follow the missing traffic plans in the network, which complicates the analysis of their deviations from the normative time of running in the network. Several studies have been aimed at researching the reliability of the train schedule in railway systems without following the schedule of cargo trains [4,5].…”

A method has been developed to simulate propagation of train delays in branched railroad ranges using modified epidemiological SIR models. These models take into account the mutual influence of trains with different priorities in the flow. This makes it possible to study the heterogeneous dynamics in the propagation of delays among trains of different priorities. To consider the propagation of the primary delay in space and time, it is proposed to represent the topology of the railway network in the form of an undirected graph with reference to the edge of the graph in the mathematical system of differential equations of the SIR model. This unifies the process of constructing SIR models for each edge (section) of the network graph and reduces the dimension of the problem. To take into account the influence of the "network effect", it is proposed to determine the transit coefficient for each station of the section. This coefficient helps calculate the number of delayed trains for adjacent sections. To set SIR models, it is proposed to use empirical data on the propagation of the average delay in the standard traffic schedule in the corresponding section. For the sequential solution of SIR models corresponding to interconnected network sections, an algorithm is applied to turn the network graph into a directed tree the root of which is the station where the delay occurs. Tests on modelling the propagation of train delays in the railway network are carried out taking into account the mutual influence of different categories of trains in the flow and the built-in time reserves for the restoration of movement. The obtained simulation results have confirmed the adequacy of the solutions and helped quantify the influence of primary delays and the amount of time reserve in the schedules of trains of various categories on the reliability of the standard train schedule

In the article, the approach on the development of management decisions for correct selection of trucks is presented, in the conditions of uncertainty and the stochastic nature of demand for transportation of a grain on the section of a supply chain named "a grain elevator - the sea terminal". The main problems arising at delivery of grain cargoes in a supply chain with the participation of automobile and sea transports were described for justification of relevance of the research. A mathematical definition of the researching tasks was made for the search for the rational management decision at forming a rational structure of the park of the trucks transporting the agricultural products to the sea terminal. Numerous management decisions based on the principles of fuzzy logic have been developed. The values of the input factors are proved in the form of a set of linguistic variables for making a correct management decision. Cargo capacity of the ship coming to the port and amounts of grain which is in a reserve directly on the sea terminal are consider to be definite quantitative characteristics of each set of a term-number.
