Fault Diagnosis-techniques are today very important, for example in Robotics section. Such Robotic-Systems are becoming increasingly significant in critical applications, an important part of which are safety and reliability. We will introduce a new approach to reflecting the residual number of critical failures. There are currently very few processes enabling us to predict the reliability of the critical failures or the critical failure rate for critical systems. Furthermore, we will focus on distinguishing the critical failures in the software, for example software for real-time-systems. We will thus distinguish both critical as well as non-critical failures in the Software. It is mandatory to look at two processes, those of detection- and correction process. To develop an approach it is necessary to determine corresponding distribution functions and model assumptions.
The paper provides an overview of how to create an estimator focusing on failure-defection in safety related systems. Stochastic play a very important role in safety technology. With the help of it, safety systems may be released reliably after an assessment. With the help of the probability theory meaningful statements are achieved and based on them, realistic forecasts may be given. However, in order that reliable forecasts can be conducted, new approaches in thinking need to be developed. This paper serves to give a short synopsis about the actual problem of the probabilistic safety technology on the base of stochastic.
In that, the test methods, however, plays the most important role as the test results are source vectors for probabilistic models. However, this paper tries to describe a suitable, innovative method that will correctly estimate the safety parameters. The first part explains the necessary basic tools. Furthermore, the safety technology is explained with stochastic playing a central role in it. Following this, the approach for the construction of the estimator is introduced. Concluding, the summary and an outlook will be given. To a greater extent than previously, safety related systems have been developed, produced and released to the market. For this reason it is essential, to know and correctly and reasonably apply the current international norms for functional safety as a basis for systems that are used in safety-critical applications.
