Abstract: A system and method for providing a digital simulation of a technical installation, and a corresponding computer program product, wherein the digital simulation is dynamically generated such that the digital simulation is adapted to a specified training scenario. This is accomplished using a provided basic class, which implements, independently of devices, functions of elementary hardware components, and using a library of virtual devices, which deterministically simulate the topology and the functional behavior of corresponding real devices. The virtual devices have a hierarchically nested structure, such that a hierarchically higher device comprises at least one hierarchically lower device and/or at least one of the elementary hardware components.

Abstract: A method calculating reliability parameters of a technical installation is provided. The reliability parameters are calculated using a modified Markov minimum cut method in which probabilities of a plurality of components failing on account of a common cause and the property of a component or subassembly with self-diagnosis are concomitantly included in the calculation of the reliability parameters. The input parameters for the calculation model are determined from messages and/or subsystems in the technical installation or from the overall installation. The failure and repair rates calculated may be used to predict the reliability, availability, maintainability and safety of the technical installation.
