A self-adaptive system (SAS) is capable of adjusting its own behavior in response to any change in its operating environment. It is able to automatically adapt at runtime by adjusting its own parameters or components of the system in order to cope with the dynamic surrounding environment. However, adaptation actions should be identified as per the particular change in the environment, i.e. “What kind of change is required?”. The aim of this literature study is to address the scope of dynamic integration of the new parameter or new component at runtime in SAS. The following set of questions is essential to fulfilling this literature study.

•  Which adaptation techniques are better?
•  How much reliable and safe it is?
•  Is it feasible to implement combination of techniques in SAS?
•  What are the impacts and cost factors?
•  How to increase the performance of the SAS with adaptation techniques?

Advancement of technology and their impact on the real-world can be assessed by how safe it is. It is a primary role of a safety engineer to assess the risk via a process relevant data and learning from past lessons. Due to advanced and autonomous technology, a study for continuous and dynamic risk assessment is required. Aim of this literature study is to address the dynamics of risk and AI-based assessment techniques. The following set of questions is essential to fulfilling this literature study.

•   What are the dynamics of risk?
•   Which quantitative/qualitative risk assessment techniques are available?
•   How AI-based risk analysis is feasible?
•   What is the impact of human factors on AI-based risk assessment?
•   Which AI-techniques can be useful for risk assessment?

We hear today a lot of confusing terms such as digitization, digitalization, and digital transformation. All of them emphasize the importance of bringing technology into the business, health, and education sectors. But what should be done? When? and how? The difference between these terms is not clear.

In this topic, you need to sketch a proper definition for these seemingly identical terms and to find the fine thread that draws the boundaries between them. Examples or use cases from different application domains would enrich your claims!.

Multi-criteria Decision Analysis (MCDA) is a method developed in operations research that is used often in the context of decision making. The Decision-making process is complex in nature. It uses a set of evaluation criteria and constraints to generate a set of optimized alternative decisions. It is required that the evaluation criteria and constraints are well defined from the beginning and have a clear expected range of values. But in real-life application, a lot of uncertainty is involved in the process. 

Your work on this topic is to:

1. investigate how the uncertainty in defining the evaluation criteria and constraints would affect the quality of the set of the generated alternative decisions.
2. show how uncertainty can be integrated into MCDA method.

For testing autonomous vehicles, it is required to capture driving situations and maneuver in real world. This seminar work should examine how situations and maneuvers are identified automatically. The focus should be on the unsupervised learning by using auto-encoders.

Reasoning is the act of thinking about something in a logical and sensible way. Such reasoning aspects are of highly employed during design stages of systems engineering., however with the ever-changing topology of cyber physical systems, the need for runtime reasoning is slowly gathering pace and especially in the field of runtime safety assurance. It will be interesting to know different perspectives of runtime reasoning and their respective goals.

The work will comprise of SLR of runtime reasoning methods presently being researched upon, followed by a qualitative evaluation of how they can influence runtime safety assurance.

Machine learning (ML) algorithms are increasingly being used in data-driven approaches for systems development. Their venture into safety-critical application domains like autonomous driving, Industry 4.0, smart grid, etc. is of particular relevance. Unlike established safety-critical components, outcomes of components containing models based on ML algorithms, can neither be proven nor assumed to be correct in any situation. ML based components which are being used for runtime applications like detection and decision making are often subject to various uncertainties which in-turn might affect safety assurance. It will be vital to gather information on different possible uncertainties which arise because of using these ML based components.

The work will comprise of SLR of uncertainties in ML algorithms used in safety critical applications, followed by creation of a classification of these uncertainties.
