Statement of the problem. The subject of the research is information models of a complete life project in the sector of architecture, design and construction and maintenance of buildings and structures. The purpose of the research is to optimize BIM technologies by building a model based on a discrete vector data description. Results. Analyzed the main obstacles to the widespread introduction of BIM technologies and procedures for the full life cycle of a construction project in the practice of the construction complex of the Russian Federation throughout the entire life cycle of the project, including the stages of construction, operation and disposal, as well as global trends in this process. The method of BIM dimension reduction based on discrete vector data description is formulated. The technology of forming a hierarchical dynamically added and updated information base BIM, taking into account the possibility of its aggregation, has been developed. The algorithms proposed in this work are implemented in the shell of a relational database management system. Conclusions. BIM dimension reduction, based on a discrete vector description of data, allows youto completely solve the problems of both designing and updating the BIM information base, and its transfer between project participants. BIM data formats are determined by the stage of the complete project life cycle. Fully functional for the stage of determining the scope of work on a project, BIM is one-dimensional and is simply determined by the vector of clusters of a lower degree of integration, which allows you to completely overcome all obstacles to the widespread introduction of BIM technologies and procedures of the full life cycle of a construction project into practice. The optimal shell for the implementation of BIM technologies is relational databases.

Постановка задачи. Предметом исследования являются информационные модели полного жизненного проекта в секторе архитектуры, проектирования, строительства и эксплуатации зданий и сооружений. Цель исследования состоит в оптимизации BIM-технологий путем построения модели, основанной на дискретном векторном описании данных. Результаты. Проанализированы основные препятствия на пути широкого внедрения BIM-технологий и процедур полного жизненного цикла строительного проекта в практику строительного комплекса РФ в течение всего жизненного цикла проекта, включая этапы строительства, эксплуатации и утилизации, а также мировые тенденции этого процесса. Сформулирован метод редукции размерности BIM, основанной на дискретном векторном описании данных. Разработана технология формирования иерархической динамически добавляющейся и обновляющейся информационной основы BIM, учитывающей возможность ее агрегации. Предложенные в работе алгоритмы реализованы в оболочке реляционной системы управления базами данных. Выводы. Редукция размерности BIM, основанная на дискретном векторном описании данных, позволяет полностью решить задачи как создания и актуализации информационной основы BIM, так и ее трансферта между участниками проекта. Форматы данных BIM определяется этапом полного жизненного цикла проекта. Полнофункциональная для этапа определения объемов работ по проекту BIM является одномерной и определяется просто вектором кластеров более низкой степени интеграции, что позволяет полностью преодолеть все препятствия на пути широкого внедрения BIM-технологий и процедур полного жизненного цикла строительного проекта в практику. Оптимальной оболочкой реализации BIM-технологий являются реляционные базы данных. Statement of the problem.

Household electric blankets are widely used in China, but the problem of quality and safety is also more prominent, which is a serious threat to the health and safety of consumers. The structure characteristics and working principle of household electric blanket are analyzed. The hazards in the each stage of full life cycle are identified, including the stages of designing, manufacturing, packaging, transporting, utilizing and recycling. Hazard identification of each stage is made with methods of scenario analysis, safety check list, fault hypothesis analysis, hazard and operability analysis, failure mode and effect analysis and fault tree analysis, respectively.
