Within this lecture, the characteristics of technical systems are analyzed and measured concerning their hazard potential. Furthermore, measures are presented, with which the quality of technical systems in the sense of an increased life span or a safe behavior can be achieved also in the case of an error.
After completion of the lecture, students are familiar with the fundamentals for the description of erroneous technical systems and they are able to select an appropriate method, which promises the best results under economically justifiable expenditure for a given task. Besides that, the students are able to describe the error behavior of technical systems on different levels. They can distinguish between best use of the traditional methods to determine lift time, the use of redundancy to increase lifetime, Markov-chains and practical tools like FMEA and FMECA.
They shall also be able to describe and handle the faulty behavior of technical systems on different levels. Systems discussed are complex mechatronic systems like cars and airplanes as well as electrical circuits and systems. In the area of testing, the test of digital circuits and systems is considered as well as computer systems and the software running on them. In this context, they can distinguish between different fault models, appropriate for different systems, simulation and test generation as well as Design for Testability.
The students are able to qualitatively and quantitatively evaluate and rate the reliability of digital systems (hardware, software, and network).
In addition, they are able to assess the relations between physical errors, test, simulation and design for testability and to select best approach for a given application with good reasons.
