Abstract
One of the important information components in predicting the actual operational reliability, setting requirements for systems of emergency protection and diagnostics and substantiating the maintenance strategy is to assess the technical and economic consequences of possible failures in individual nodes of technical systems. When applied to stochastic objects, randomly changing their state in time, an effective way to conduct relevant research is the application of computer simulation modeling. As an example of such a stochastic object, the article describes an automated hydraulic system, which includes the storage tank level sensors, centrifugal pumps, consumers, randomly changing the queries of water in time, and discrete algorithm control of the water level in the tank. The software model provides a simple and convenient way for the user to configure settings, as well as intuitive animated on-screen representation of the modeling process and its results. Modeling different types of the system failures has made it possible to identify the characteristic disruption of normal system operability and to evaluate the relevant technical and economic consequences.
Keywords: stochastic system, the consequences of failures, simulation.
