5G wireless networks are of great interest for research. Network Slicing is one of the key technologies that allows efficient use of resources in fifth-generation networks. This paper considers a method of resource allocation in 5G wireless networks using Network Slicing technology. The paper examined a model for accessing radio network resources, which includes several solutions to improve service efficiency by configuring the logical part of the network. This model uses network slicing technology and elastic traffic. In the practical part of the work, transition intensity matrices were constructed for two different configurations.

The paper examines current issues of modeling and forecasting market parameters for transport companies providing services for the transportation of industrial enterprises’ good, such as cost, time, speed and volumes of delivery of finished products to consumers, and also assesses the potential capabilities of transport companies to provide the required quantity and quality of transport and logistics services. The aim of the study is to determine the area of reliable forecasts of transportation indicators for each interval value of the cargo delivery shoulder, taking into account the company’s market share. Modeling of the time parameters of cargo transportation was carried out based on road transportation conditions and the time of year. When implementing modeling procedures, the required statistical basis for parameters of travel time and distance on the route was formed on the basis of data from specialized applications for analyzing indicators of transport and logistics services of freight vehicles. A family of forecast curves was obtained for various variants of forecast models of speed and travel time, as well as interval values of delivery lengths for the initial set of transport and logistics companies. and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.

Fifth-generation networks are of great interest for various studies. One of the most important and relevant technologies for efficient use of resources in fifth-generation networks is Network Slicing technology. The main purpose of the work is to simulate the probabilistic characteristics of blocking requests for access to wireless network radio resources. The main task is to analyze one of the options for implementing a two–service model of a wireless network radio access scheme with two slices and BG traffic. In the course of the work, the dependence of the probability of blocking a request depending on the intensity of receipt of applications of various types was considered. It turned out that the probability of blocking a type i application has the form of an exponential function. According to the results of the analysis, request blocking occurs predictably, taking into account the nature of incoming traffic. Previously, there are no significant drawbacks in the considered model. The developed model is of great interest for future, deeper and long-term research, for example, using simulation modeling, with the choice of optimal network parameters.
