Context. The problem of rational allocation of medical facilities of inhabited locality was considered. Methods of evaluating the effectiveness of using the existing medical network and finding ways to improve it when implementing urban development projects were proposed. Objective. The goal of the work is to build and study the procedure for solving the problem of placing medical facilities, considering the existing infrastructure of the city to fulfill the accessibility requirements. Method. A set of factors that affect the placement of a medical facilities and allow a systematic and reasonable decision to be made in choosing a location has been formed. A method for solving the problem of the location of medical facilities, providing an increase in their accessibility level considering the population, its spatial distribution, existing in the settlement of road junction and traffic congestion is proposed. The procedure for solving the problem is presented in the form of an IDEF0 model. The method is based on geoinformation analysis of data, the results of which by spatial clustering are presented in the form of a set of cartographic models, the aggregate of which allows to form a decision about the location. The method allows to assess the accessibility level of existing medical facilities in the inhabited locality, create a list of places for their possible location, find areas of the locality that are not in the access zone. Results. The method of choosing the location of the medical center has been improved, which makes it possible to make decisions based not only on the shortest distance from the center to the patient, but also on the level of its accessibility. For the first time, the structure of information technology for multivariate analysis of a network of city medical centers for decision support systems using GIS technologies is proposed. Conclusions. The medical facilities location problem, which is in increasing the level of accessibility by expanding the area of medical coverage of the territory in which the city population lives by using GIS was practically fulfilled as an IDEF0 model that defines the procedure for solving the problem and choosing the location of the medical center. The practical significance of obtained results has been proven on a practical example-an analysis of the existing hospital system for the provision of emergency medical care in Kharkiv.

The subject matter of the article is the processes of managing the material resources of the project. The goal of the work is to form a generalized approach to the management of material resources project by determining and formalizing the management processes of them. The following tasks were solved in the article: the processes of managing material resources project, which based on the process approach, are formed; place of these processes in the PMBOK structure is defined, these processes are integrated with other project management processes; a formalized presentation of the project management processes of the project is given; tools and methods of managing material resources of the project are identified. The following methods used are – methods of system analysis, decision-making theory, and inventory management theory. The following results were obtained – with target to make informed management decisions, it was proposed to allocate a separate area of knowledge, within which the processes of the management of material resources of the project are formed, their possible connection with the groups of PMBOK processes is shown. Based on the process approach, presentations of the processes were formalized. They are elements of managing material resources of projects. They define inputs and outputs, show interrelations with other processes of a specific area of knowledge, provide basic recommended tools and methods. Conclusions: the processes management resource described in the PMBOK methodology are analyzed. This made it possible to form possible directions for improving the project's resource support. It is noted that the solution to this problem depends on the management of the material resources of the project. A separate area of knowledge has been highlighted, within the framework of the processes of management of material resources project – the processes of evaluating material resources, procurement management and supply, distribution of material resources, managing material resources. They define inputs and outputs, show interrelations with other processes of a specific area of knowledge, provide basic recommended tools and methods. The results obtained can be useful when managing projects at any stage of the life cycle.

The subject of study in this article is the process of analyzing infrastructure objects for waste management. The current article increases the objectivity of waste management infrastructure objects estimated by developing a model and method of information technology for analyzing several indicators of these objects based on the use of spatially distributed data. Objectives: to analyze the key factors affecting the waste management infrastructure (WMI) to select possible ways to improve the efficiency of its functioning; to develop a model of the WMI objects analyzing process, which determines the structure of information technology for analyzing several indicators of these objects using spatially distributed data; to improve the method of identification and verification of data about WMI objects. The following results were obtained. An approach to the estimation of WMI objects based on set-theoretical and functional modeling of the process of analyzing these objects is proposed. The method for identifying and verifying data about WMI objects has been improved, based on considering them in the form of geographical objects, considering current cartographic and satellite data, which, in contrast to the existing ones, will allow an objective assessment of their compliance with legal and construction standards. For the first time, the structure of information technology for analyzing several indicators of WMI objects is proposed, the use of which in decision support systems will make objective judgments about the existing infrastructure based on spatial data using geoinformation systems. Conclusions. The results of the bibliographic research confirmed that effective monitoring of WMI objects to ensure compliance with legislation in the field of waste management is extremely difficult. This process requires the development of specialized models and methods focused on the use of geoinformation systems for their implementation in decision support systems. Scientific and methodological support of information technology for analyzing several indicators of WMI objects has been developed. Its usage in the tasks of estimating the state of the corresponding objects of the Kharkiv region confirmed that many of them do not meet the existing legal and building requirements, which requires close attention to the problem of waste management and the development of appropriate management decisions.

The subject of this study is the process of engineering and geodetic surveys for developing road projects. The purpose of this article is to improve the efficiency of the process of engineering and geodetic research in road design by implementing remote data from various sources and their systematization and algorithmization of use. The task is to analyze the preparatory and field stages of the process to determine possible ways of increasing its efficiency. Focusing on information flows, to develop an information model of the process of engineering and geodetic surveys and the corresponding scientific and methodological support for road design to introduce advanced technologies for collecting data about the terrain, which reduce the time of surveys and increase the accuracy of the results obtained. For this, the following methods are used: system and structural analysis, set theory, and DFD modeling. Scientific results have been obtained. The requirements of the current legislation regarding searches and the best experience of their conduct have been systematized. A set-theoretic model of information flows of the process of engineering and geodetic surveys is proposed, with the involvement of structural modeling approaches that make it possible to combine remote data from different sources and consider the dynamics of their changes and the logic of interaction. The IDEF0 model, which considers remote sensing data as a source of accurate and up-to-date information, has been developed, and the data flow diagram algorithmizes the mechanism of their combination to obtain the necessary topographical and geodetic materials. The developed scientific and methodical support for information support of road design creates a structure of information technology for engineering and geodetic surveys. Its experimental use has confirmed the reduction of the time for performing geodetic works while simultaneously increasing the accuracy of the obtained geometric and geodetic parameters, which are necessary for the formation of objective conclusions when forming the estimate of the road project, determining the scope of works, etc. Conclusions. The results of the bibliographic search confirmed that the effectiveness of the topographic-geodetic survey procedure in road design is complicated by the large size of the geographical areas to be surveyed, complex engineering and geological conditions, or the presence of restrictions on the duration of work and financial resources. This leads to the need to practically implement into the project-research organizations new approaches based on highly productive methods of collecting information about the area. The scientific and methodological provision of information support for road design has been developed, in particular, the structure of the information technology of engineering and geodetic surveys. Its experimental use has confirmed the reduction of the time required to perform searches and the improvement of the accuracy of the obtained geometric and geodetic parameters of the area where the implementation of the road project is planned.
