In industry, development artefacts such as components or units, are often reused from existing artefacts to save time and costs. When development artefacts are reused, their existing safety analysis models are an important input for an early safety assessment for the new system, since they already provide a valid model. Component fault trees support such reuse strategies by a compositional horizontal approach. But current development strategies do not only divide systems horizontally, e.g., By encapsulating different functionality into separate components and hierarchies of components, but also vertically, e.g. Into software and hardware architecture layers. Current safety analysis methodologies, such as component fault trees, do not support such vertical layers. Therefore, we present here a methodology that is able to divide safety analysis models into different layers of a systems architecture. We use so called Architecture Layer Failure Dependencies to enable component fault trees on different layers of an architecture. These dependencies are then used to generate safety evidence for the entire system and over all different architecture layers. A case study applies the approach to hardware and software layers.}, language = {en} } @inproceedings{HoefigZellerSchorp2015, author = {H{\"o}fig, Kai and Zeller, Marc and Schorp, Konstantin}, title = {Automated failure propagation using inner port dependency traces}, series = {2015 11th International ACM SIGSOFT Conference on Quality of Software Architectures (QoSA), Mai 2015, Montreal, QC, Canada.}, booktitle = {2015 11th International ACM SIGSOFT Conference on Quality of Software Architectures (QoSA), Mai 2015, Montreal, QC, Canada.}, pages = {123 -- 128}, year = {2015}, abstract = {Safety assurance is a major challenge in the design of complex embedded and Cyber-physical Systems.

This kind of knowledge becomes relevant when the issue is whether to change from a currently employed approach to a new one or not. An informed decision is required and is particularly important in the development of safety-critical systems. For example, for the safety analysis of safety-critical embedded systems, methods such as Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) are used. With the advent of model-based systems and software development, the question arises whether safety engineering methods should also be adopted. New technologies such as Component Integrated Fault Trees (CFT) come into play. Industry demands to know the benefits of these new methods over established ones such as Fault Trees (FT). (Methods) For the purpose of comparing CFT and FT with regard to the capabilities of the safety analysis methods (such as quality of the results) and to the participants' rating of the consistency, clarity, and maintainability of the methods, we designed a comparative study as a controlled experiment using a within-subject design. The experiment was run with seven academic staff members working towards their PhD. The study was replicated with eleven domain experts from industry. (Results) Although the analysis of the tasks' solutions showed that the use of CFT did not yield a significantly different number of correct or incorrect solutions, the participants rated the modeling capacities of CFT higher in terms of model consistency, clarity, and maintainability. (Conclusion) From this first evidence, we conclude that CFT have the potential of being beneficial for companies looking for a safety analysis approachfor projects using model-based development.}, language = {en} } @inproceedings{JungJedlitschkaHoefigetal.2013, author = {Jung, Jessica and Jedlitschka, Andreas and H{\"o}fig, Kai and Domis, Dominik and Hiller, Martin}, title = {A controlled experiment on component fault trees}, series = {International Conference on Computer Safety, Reliability, and Security (SAFECOMP 2013)}, booktitle = {International Conference on Computer Safety, Reliability, and Security (SAFECOMP 2013)}, publisher = {Springer}, address = {Berlin, Heidelberg}, pages = {285 -- 292}, year = {2013}, abstract = {In safety analysis for safety-critical embedded systems, methods such as FMEA and fault trees (FT) are strongly established in practice.

To compare CFT to FT, we conducted a controlled experiment in which 18 participants from industry and academia had to apply each method to safety modeling tasks from the avionics domain.

Growing system sizes and the rise of Cyber-Physical systems confront safety engineers with large sets of configurations to be analyzed. Current approaches are usually carried out at design time and do not address the need for automated assessments in the field. With Component Fault Trees (CFTs) there exists a component-based methodology that enables an efficient modular composition of safety artifacts. The combined model is a system-level CFT that can be analyzed by means of popular Fault Tree Analysis techniques that are widely accepted in the industry. However, when composing models, their interfacing elements must be connected manually which impedes the automation of the procedure. In this work, we introduce the notion of flow types that represent a particular kind of component interaction and define a taxonomy of related failure behavior. By annotating CFTs with types, a machine-readable vocabulary is provided that allows for an automated interconnection of their interfaces. This way, the automatic composition of models according to system architecture is enabled, allowing for automated safety assessments on system-level.
