Information Database

In this article, we analyze the modern concepts in the field of the aeronautical equipment integrated logistical support (ILS). The key element of the traditional logistical support system under consideration is the data on detected failures and malfunctions, recorded in the air flight and maintenance log (AFML), chart-orders, non-routine write-ups and accumulated within the structure of the logistic support analysis database. We propose a method for expanding the ILS capabilities by means of including of an additional element, called the flight information database, in the logistics center structure, along with the traditional database for analyzing the logistical support. This database is constantly growing during the aircraft operation. It also contains the values of the parameters recorded by the standard onboard flight data recorder, which reflect the state of the onboard systems. The inclusion of a flight information database into the structure of the logistical support center makes it possible to implement the probability-guaranteeing estimation method in respect of the risks, associated with the aircraft technical condition, for benefit of the integrated logistical support. The proposed method uses an inverse probabilistic criterion (quantile) as an integral characteristic of the aircraft systems technical condition. This is fully consistent with modern approaches to organizing condition-based maintenance. Among these approaches, the data-driven methodology (DDM) has the greatest potential and practical efficiency. The applicative value of the described method is in the fact that its implementation needs neither a priori information about the principles of the maintained equipment operation, nor information about the functioning principles of the on-board controller network, which is used to control the equipment physical parameters. In this article, we also present the accuracy estimates of forecasting the residual life of an aircraft gas turbine engine, using the proposed method. These estimates are based on the actual flight data presented in the National Aeronautics and Space Administration (NASA) repository.

A comprehensive study of the production and consumption waste management system was carried out with an emphasis on urgent problems in this area in the transport and construction sectors. The concept of ensuring the ecological safety of the “man — natural environment” system has been formed. Sources of ecological danger in the course of the reference with a waste in transport and building sphere are defined. Ecologically safe handling of a waste and maximisations of repeated application of a resource component (secondary resources) with a view of involving in economic circulation are applied for the first time to system studying modern research methods: the SWOT-analysis and the Preliminary analysis of Hazard». Implemented the scientific substantiation of methods, criteria, levels and system of requirements of maintenance of ecological safety in studied spheres of economic activities at all stages of the reference with a waste and secondary resources with a view of minimisation of formation of a waste and the maximum involving of their resource component in economic circulation is carried out. The system analysis of an ecological admissibility, technical possibility of use of resource potential of a waste as secondary resources in considered fields of activity for their repeated application is carried out at production, works, energy. By results of research practical measures on perfection of system of requirements ecologically safe handling of a waste are offered, levels of ecological safety of settlements concerning influence of a dangerous waste are generated.

In article development of “digitalization” in transport and logistics spheres is described. New unique services for users of transport raise its safety, convenience and availability and demands perfection of system of legal and technical regulation, creation of through technologies and information security maintenance. The electronic trading platform of freight traffic and its integration with an automobile complex will accelerate granting to multimodal services to terminal-warehouse complexes, financial to services and insurance that becomes a basis of a transport-logistical platform of the country.

The role of integrated logistical support in the after-sales stages of the life cycle of construction sites is considered. It is shown that the effective management and operation of buildings and structures, their engineering equipment, is impossible without the analysis of logistical support, which is carried out at the design stage and is refined at the following stages of the life cycle of construction objects on the basis of accounting and analysis of operational information on the management of technical condition of construction. An information model of integrated logistic support for the life cycle of construction structures has been developed. It is shown that the core of the information model is an integrated information environment that contains information about the construction object, resources and processes, ensures that the data involved in the life cycle of the entity is stored and accessible. Data is added to the information environment by all participants throughout the lifecycle of the objects, allowing you to receive and analyze up-to-date project documentation and visualizations at any time. The stages of the life cycle of construction objects in an integrated information environment are analyzed.

This article presents the mathematical modeling of export energy costs. The knowledge-intensive products export energy costs are a set of financial, material, labor costs and resources consumption. Export costs are a multilevel system of indicators. The author sets out the order of mathematical modeling. At the first stage, the main trends in reducing export energy costs are identified. A set of integrated logistics support measures is modeled. The modeling of knowledge-intensive products export energy costs is a system of technical and economic indices and a cost value dependance: Maintenance and Repair, Material and Technical Maintenance, Business Model of After-Sales Service, Formation of the Cost of Insurance and Investment Management Strategy. Formulas, practical calculation examples and graphs are presented. The Ishikawa systematic analysis method is used to visualize data and dependence relations. The author's mathematical modeling of knowledge-intensive products export costs includes the calculation of integrated logistic support costs. Exporting countries require a high level of technical products efficiency. It has been established that "the more complex a knowledge-intensive products is, the higher the reliability of systems is". Reliability indices are basic. The author's scientific study confirms a hypothesis of the knowledge-intensive products export feasibility only with high reliability and efficiency factors. The author developed a set of integrated logistical support measures for knowledge-intensive products.
