Seven methods in ISO that needs to be adapted according to Salay et al. Open Access Dissertations and Theses. In conclusion, we determined that STPA can be used in an ISO compliant manner and also provided guidelines to fulfill any gaps identified. Furthermore, it is fully compliant with the upcoming standard ISO May 28, July 13, mrksbrg. It is important to note that we did not have to modify STPA but only augment it to achieve this. While this paper only reports the first steps toward a larger research endeavor, we report three adaptations that are critically needed to allow ISO compliant engineering, and related suggestions on how to evolve the standard.

They concluded that seven methods need to be adapted, see the first two columns below. In conclusion, we determined that STPA can be used in an ISO compliant manner and also provided guidelines to fulfill any gaps identified. Implications for Research Corroborates findings by Salay et al. To get access to the document please fill in the following form. Machine learning enables many novel applications, and we want to use it also in safety-critical contexts.

In conclusion, we determined that STPA can be used in an ISO compliant manner and also provided guidelines to fulfill any gaps identified.

Costs for application development are lowered by offering the integration of a generic standard solution instead of an application-specific solution. Furthermore, it is fully compliant with the upcoming standard ISO Implications for ML Practitioners Specify requirements isoo the network architecture and how training should be done Use fault injection to test model sensitivity Expect novel approaches to test case generation, random data is not sufficient. Seven methods in ISO that needs to be adapted according to Salay et al.

Although the thezis suggests using traditional hazard analysis techniques to identify hazards and to perform safety analyses, a literature review shows the limitations of these techniques to handle the increased complexity of modern vehicles, caused by the growing number of features added to them.

It is important to note that we did not have to modify STPA but only augment it to achieve this.

By properly understanding this, we could work from two directions to realize safe systems with machine learning features — we could develop learning behavior in a way to meet standards, and we could adapt standards to meet the nature of machine learning.

We interviewed two experts on functional safety to get their views on the way forward. May 28, July 13, mrksbrg. TTTech Automotive, a TTTech subsidiary specialized in reliable automotive network solutions, has developed a reusable and modular safety layer that guarantees end-to-end communication integrity. The final column shows the recommended adaptations based on our interviews.

Understanding tgesis sensitive they are to disturbances is critical, for example, altering the input vector slightly should not result in a large step response although this is common. One of the main challenges faced by manufacturers is the difference in the terminologies used in the techniques and the standard. To limit the scope of the study, we focused on the 27 methods that are highly recommended for ASIL D.

Just like many others, we are interested in knowing what parts of standards for development of safety-critical systems contradict the nature of machine learning.

MacSphere: Using STPA in an ISO compliant process

TTX SafeCOM reduces development and certification costs by reusing a theais common software component to ensure safe communication. This pre-certified safety layer reduces costs for application integration.

For example, a neural network is trained to create a mapping from an input to an output, but the corresponding requirements are not needed on a neuron level — instead we need requirements thesiw the network architecture and the approach to training. Our favorite study that does this is Salay et al. Implications for Research Corroborates findings by Salay et al. Standing on the shoulders of Salay et al.

Due to the increasing number of safety-related functions in automobiles, the amount of electronic control units in them is also rising. ML enables many novel applications, also in safety-critical contexts.

Hazard analysis is an essential activity in the development lifecycle of any safety-critical system. Thus, fault injection testing is important for machine learning. We intend to conduct interviews with additional domain experts in the fall.

They concluded that seven methods need to be adapted, see the first two columns below. The solution is application-independent and can be applied tuesis.
