Comfortable urban environment currently determines the economic development of the region as a whole, affects the socio-political situation, the rate of migration and investment. The analysis showed that the majority of municipalities have an imbalance in the factor space, which negatively affects the development of non-productive sectors of the economy and the main sectors of the economy. Open dialogue of the population with the city authorities allows to form the most effective methods on the way of creation of favorable regional climate, to make it competitive and to develop priority business directions.

The paper proposes the composite architecture of a multi-agent bionic search system based on swarm intelligence and genetic evolution for solving the problem of covering sets. The modified paradigm of the particle swarm is described, which provides, unlike the canonical method, the possibility of using positions with integer parameter values in the affine space. Mechanisms for moving particles in affine space to reduce the weight of affine bonds are considered. The developed position structures (chromosomes) are focused on the integration of swarm intelligence and genetic evolution. The time complexity of the algorithm, obtained experimentally, coincides with the theoretical studies and for the test problems considered is О(n2)- О(n3).

The study aims to develop objective methods for ranking management decisions on risk management in the socio-economic system of the region. Insufficient development and adaptation of the existing methodological framework for risk management to the tasks of analyzing the directions of development of socio-economic systems and insufficient use of accessible tools for management decisions generates situations of imbalance in the involvement of natural labor and material resources in the region's reproductive process, violations of harmony, systemic unity, principles of maximizing effect and replenishment factors of production, which entails a threat of failure to meet the target strengthening conditions and the synergy of risks. The study examined sources and risk factors of regional development, types and stages of risk management, expert evaluation of management alternatives for economic, environmental and social risks, explored the possibility of adapting the verbal analysis methodology for ranking management decisions. As a result of the work, a method of formalized analysis of supporting situations is proposed, which, in the context of regional risk management, can provide objective estimates of the preferences of management alternatives.

The issues of violations of the terms of delivery of goods on the railway network are considered. The main reasons for the violation of the delivery time are systematized on the example of the North Caucasian Railway. The North Caucasian Railway serves the ports of the Azov-Black Sea basin and the consignees of the Southern region. Over the past 10 years, the volume of loading of export cargoes to the ports of the Southern region has increased by more than 47%. Despite the relatively high reliability of cargo delivery, a negative trend in the increase in financial risks of the company RZD was noted. An analysis of the claim work was carried out, in connection with the violation of the delivery deadlines. The issues of speed and delivery of cargo and empty shipments at the North Caucasian Railway are considered. The main reasons for the arrival of goods with broken delivery dates were: the receipt of wagons with broken delivery dates at the joints of the road; Excessive availability of wagons to ports and port oil depots; an increase in the number of passenger trains in the summer. Mechanisms for managing the delivery time in rail transport on the basis of logistics and information technologies have been developed. Expansion of the zone of logistics management of railways traffic to ports based on the use of information systems that allow monitoring of operational work, identify problems of the road network, will reduce the load on the infrastructure of the port roads, fulfill all budgetary targets, and obtain additional profit.

The distribution center is one of the main elements of the distribution system, which forms the structure of the movement of resources. It is responsible for ensuring the efficient allocation of the flow of resources. The effective location of the distribution center allows you to reduce the cost of allocating resources to 30%. The method of solving the problem of effectively securing demand zones for a particular distribution center is proposed in this article. The uncertainty of the initial parameters is taken into account when solving this problem. The result of solving the problem of determining the effective location of distribution centers is a set of fuzzy intervals. These intervals determine the coordinates of the location depending on the parameters of the task, namely, the demand of consumers, the capacity of distribution centers, the distance between the resource consumers and the center. The location of the distribution center will be determined not by a specific numerical value, but by a fuzzy interval that will determine the region of the best location. A software application is developed that allows you to specify parameters in a fuzzy interval form, on the basis of which the results of solving the problem are formed. The cost of delivering resources to consumers changes significantly with the change in the number and location of distribution centers, so the issue of rational distribution and the number of centers is important. This task becomes especially relevant when a new distribution system is being designed, or the existing system is being modernized.
Keywords: distribution centers, the demand, the uncertainty of the initial parameters of the fuzzy intervals, potential interactions, grouping
It is considered a centrally symmetric stress-strain state of the rock mass near the underground spherical cavity taking into account the technological heterogeneity of the rocks of the near-edge region. The mathematical model was developed and analytical solutions were found for this problem. The technological heterogeneity of the elastic properties of the rock mass material was modeled by a radially inhomogeneous coefficient of elasticity at a constant Poisson's ratio. The variable coefficient of elasticity for heterogeneous rocks was approximated by a generalized polynomial with undetermined coefficients. On the basis of experimental data, a numerical calculation of the stress-strain state components for the problem was carried out, and characteristic effects were detected.
