Abstract:
A method for computer-aided simulation of operating parameters of a technical system including a plurality of modules which each contain one or more components is provided. Failure events with associated downtimes for each component are simulated in a predetermined operating period using a first probability distribution for the moment of failure of the components and a second probability distribution for the length of the failure of the components, and a third probability distribution for a degree of reliability of the modules is determined. Based upon the probability distributions for the degrees of reliability of the modules, operating parameters of the technical system are simulated for the predetermined operating period. The method is used for any technical facilities, in particular for energy generation facilities.

Abstract:
IN a method and a device for determining a probability of occurrence that an overall system fulfills a predefined system performance, the overall system is composed of instances of different classes of partial systems, and each class of partial systems has an associated class fault tree. The method has the following steps: (a) calculating (S1) an overall performance for each failure combination of the number of non-failed instances within a class; (b) automatic selection (S2) of failure combinations, the calculated overall performance of which fulfills the predefined system performance; (c) automatic generation (S3) of an overall fault tree based on the class fault trees of partial systems as a function of the selected failure combinations; and (d) evaluating (S4) of the generated overall fault tree for calculating the probability of occurrence of a fulfillment of the predefined system performance by the overall system.
Abstract:
A technical system is broken down into a plurality of subsystems, each of which is allocated a time-dependent distribution function which describes the probability of failure of the respective subsystem. The distribution functions are linked to one another to form a time-dependent system distribution function which describes the probability of failure of the technical system.
Abstract:
A method and a respective apparatus for calculating a risk reserve value for a machine is provided. A risk reserve value for a machine is a potential penalty the manufacturer of a machine has to pay to the owner or operator of the machine in case the machine does not start at a guaranteed success probability value. The method and respective apparatus can be used in business considerations as well as the construction of machines with regard to provide guarantee values to a customer.
