  • On the issue of the process of managing the property complex of the territory of the municipality

    The article highlights a number of problems that accompany the process of managing the property complex of the territory of the municipality. Issues related to the accounting and analysis of the state of objects of the property complex are considered. The need for systematic research is noted to justify decisions on the use of the city as a resource that provides a comfortable and safe space for life. Improving the process of managing the property complex is an urgent task for the development of cities around the world. An analysis of foreign experience indicates a common understanding of the criteria for the quality of the urban environment and the goals of the reorganization of urban space. When planning the development of urbanized territories, the peculiarities of the city, natural and climatic conditions are not always taken into account, which has a detrimental effect on the quality of the urban environment. It is shown that the effectiveness of the management of the property complex depends on the correct choice of the strategy for involving objects in the economic turnover, restoring their functional significance and ensuring environmental safety. To select effective solutions when solving issues of the use of the territory, it is proposed to use the method based on fuzzy sets, as the most optimal in conditions of high uncertainty and complexity of the processes under consideration.

  • Problems and Prospects for the Development of International Transport Corridors in the Space of the Countries of the Eurasian Economic Union

    International transport corridors in the space of the countries of the Eurasian Economic Union in their structure combine various types of transport routes, transport infrastructure facilities, vehicles, and transport authorities. The decisive factor in the development of international transport corridors on the territory of the EAEU is the spatial localization of the integration group.

  • Mathematical, algorithmic and software support for the problem of calculating control actions based on fuzzy logic when simulating the movement of a load in a portal crane simulator

    The article is devoted to the development of models and algorithms for calculating control (advisory) actions when training operators of technological processes (on the example of reloading processes and, in particular, portal cranes) on computer training complexes (CTC). A complex of models and algorithms is proposed, based on which control actions are calculated regarding discrete crane controls and the possibility of moving the load to a target position with minimization of oscillations at the end point is provided. These models and algorithms use variable parameters of the technological process, described by linguistic variables, and customizable characteristics of crane models and engines, which allows calculating control actions depending on the type of crane, the specifics of the technological process, the training methodology used for operators and other significant factors. Application of the advisory system based on the developed models and algorithms promotes to improve the training process for operators of reloading cranes at CTC and, as a result, to reduce the probability of emergency situations, reduce time and energy costs.

  • The main aspects of adaptive management of the property complex of the territory

    The development of urbanized territories, as a rule, is associated with the expansion of urban space, which, in turn, leads to an increase in the load on transport systems and social infrastructure. Geographically divided areas have weak interconnection due to the lack of highways and public transport. At the same time, the infrastructure of the outskirts differs from the center in scarcity and monotony. An increase in the urban population, a change in the natural and climatic conditions of residence, the environment in urbanized areas, a steady increase in the value of real estate make it necessary to accelerate the pace of the integrated development of urban spaces. The most important task set today for the subjects of management of the municipality is related to the optimization and effective use of the objects of the existing property complex. The renovation process will affect morally obsolete and abandoned facilities that impede the integrated development of the territory, reduce investment attractiveness and reduce the volume of the tax base. Adaptive management will increase the efficiency of the use of existing territorial resources, improve the social and environmental conditions of the urbanized space. Involvement of the existing reserve of real estate objects in the city center will create conditions for the formation of new public and business spaces in the city, which is important for the comfortable living of the population.

  • On evaluating the effectiveness of the use of transport models for fire management

    The transport problem (TS), as one of the forms of the linear programming problem, allows you to optimize the distribution of limited resources of fire departments (fire trucks, equipment and materials) over several simultaneous calls. The use of TOR, as an alternative to the current deterministic departure schedule, for resource allocation should increase the response efficiency, i.e. reduce damage. The article proposes an algorithm for estimating this amount of damage reduction based on the use of available official statistics on fires and taking into account the structure of the TK.
