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.
