Method, Model and Information Technology for Determining the Value of Measurement Infor-mation in The Interests of Safety of Technical Objects

Problem. Extending the service life of technical objects is inextricably linked to the safety of their operation and impact on the environment. The decision should be made based on the analysis of information received from many sensors of different types. Goal. The goal is creating method, model and information technology for determining the value of measurement information in the interests of security of technical objects. Methodology. Solution of the set tasks involved application of the mathematical analysis, decision theory, metrology, theory of signal detection etc. Originality. The article presents a method of determining the value of measurement information for the safety of bridge structures, which is based on the theory of statistical solutions. Results. It has been proven that when developing information technologies on large bridges and other similar technical objects, it is necessary, on the one hand, to meet safety conditions, to minimize the average risk and, on the other hand, to choose information whose value exceeds a certain permissible threshold, which is different for bridge structures and depends on its equipment with sensors, the information technologies that will be used, and on many other factors that are characteristic of the bridge and its operating conditions. Practical value. The method, model and information technology developed for the bridge structure can be applied to other technical objects as well.
