Reliability of Technical Systems
Zuverlässigkeit technischer Systeme
Last Updated: 2026-02-05 15:14:30
Abstract
Probabilistic methods of reliability evaluation, importance analysis, reliability prediction etc. Examples of use in the fields of mechanical and electrical engineering, computer science. Established techniques e.g. Fault Tree Analysis, Reliability Block Diagrams, Markovian chains, FMEA. Comparison and improvement of systems. Model extension to renewable units and dependent failures.
Objective
Demonstration of the most important terms and theoretical basics of reliability analysis of technical systems. Therewith basic knowledge is provided in order to also assess complex system architectures in terms of safety technology and finally to improve them. In doing so it is the goal to quote reliability and availability figures of a system and its components by quantitative parameters, e.g. failure probabilities. These indicators also serve as parameters in reliability models and simulations. It is helpful, to become acquainted with current modelling and simulation tools and their practical application. Realistic models and simulations are achieved by a step by step inclusion of operating impacts, e.g. consideration of dependent failures. Software tools for specified technologies are introduced. Examples from the fields of mechanical and electrical engineering and also computer science give the participants an opportunity to deal with practice-relevant problems.
Content
The lecture teaches methods of reliability estimation using established models, which permit to infer from reliability of components to reliability of an entire system. Theoretical contents are accompanied by numerous practical examples. Software tools are introduced. The lecture includes probability theory, descriptive statistics, and Boolean Algebra. Worthwhile techniques of system modelling and evaluation are introduced. These techniques are Fault Tree analysis, Reliability Block Diagrams, and Markovian chains, which may serve for system comparisons and improvements. The application field of reliability theory is wide. It includes mechanical and electrical engineering and also computer science (reliability of hardware and software) etc.
