Formalization of Life Cycle Stages of Geographic Information Products Creation at Research and Production Enterprises

Purpose of research. The purpose of this article is to formalize the processes of creating geographic information products (GIP), within its life cycle (LC), taking into account heterogeneous types of GIS resources of a research - production enterprise (RPE). A typical subsystem of AIS infrastructure of an enterprise is an object of this study. Methods. On the basis of an analysis of scientific sources and standards it was shown that changes in traditional approaches, principles, models are necessary in the creation of GIP. It is also necessary to change infrastructure and resources management of NPP. Presented in tabular form model is describing GIP life cycle taking into account the list of required resources and provisions. Features of LC GIP based on geoinformation technologies processes have been identified. The general approach in formalization of stages describing processes of GIP processing and operation of typical elements of GIS enterprise is described. A model of automated processing process (APP) of GIP is developed on the basis of system representations and theoretical-multiple approach. It is represented by the Cartesian product of vectors. The role and features of information support in the development of GIP are highlighted. Results. The analysis of GIP functioning features, as well as developed structural graphic and tabular presentation, made it possible to identify links between GIP features and stages content of their LCs. The results will allow clearer positioning of GIP elements and components presented for development and operation, especially in GIS NPP. The results will provide an opportunity to define the requirements for systems of this class adequately. Conclusion. The presented LC GIP models, taking into account the identified features of their construction and functioning, will allow, in the future, setting and solving modeling and management system tasks of this class.

Safety assessment of Instrumentation and Control systems (I&C systems) of NPP is performed during expert reviews of nuclear and radiation safety in the framework of the licensing process at all life cycle stages of I&C systems. Life cycle stages of NPP I&C systems, which are determined by current guides, rules, and standards of Ukraine, are considered in the chapter. A short overview of the main principles of safety regulation of nuclear facilities, licensing, and expert review of nuclear and radiation safety is presented. Specific safety assessments of NPP I&C systems at different life cycle stages are analyzed (in particular, a list of documents proving NPP I&C safety that should be submitted for expert review at each stage is given). Such assessment is a labor-intensive process that requires processing considerable amounts of a variety of information. Hence, it is reasonable to provide experts with information support for assessing the safety of NPP I&C systems. The chapter gives suggestions and examples of practical implementation of the automated system for support of expert activities and considers the knowledge base for I&C systems.

This publication continues the research, the main task of which is the creation of a geographic information system and a geodatabase intended for information support of roadside services. The authors swap their experience in developing a geographic information system in the field of roadside services in the Irkutsk region. It acts primarily as a tool for spatial analysis and a means of displaying thematic maps, providing great opportunities for optimizing the existing network of roadside infrastructure and rational placement of its new facilities. Such an information system should provide an opportunity to interactively display and perform automated processing of information about all stored objects; present processing results in the form of graphic images, maps, tables, and reports. The main provisions and conclusions drawn in the work formed the basis for recommendations on the development of roadside services in the Irkutsk region. To solve this problem, we used systemic and integrated approaches, methods of geographic information mapping and spatial analysis.

The article focuses on the development and formation of a system of indicators for assessing the characteristics of asynchronous electric motors (AEMs) at various life cycle stages. The problem is solved on the basis of the topological approach to the analysis of heterogeneous electromechanical systems. The life cycle of AEM and the tasks of its information support are described. The flows of diagnostic information are analyzed. Indicators for assessing the health of AEDs at various stages of their life cycle are proposed.
