“…But not always one component has only one function, the implementation from one function can be executed by more than a component or more than one function may be assigned to a component [25,26]. Approaches like, for example, the extension from FTA including the functional dependency [27,28] show that reconsideration is necessary for the benefit of the functional orientation. Liggesmeyer [20] considers for applying FTA and FMEA by his modularized model the system and system environment, though the analysis to focus only on components and functions that are not taken into account.…”

A high number of examples in today's global industry prove that it is difficult to ensure a certain level of quality. One possible reason is the increasing complexity of modern mechatronic product systems. Interface problems due to several involved science disciplines and the lack of understanding subsystems, which are delivered by different suppliers, make it difficult to identify critical components and specifications of elements. Furthermore, it is even harder to estimate the effects of elements because of their unknown dependencies and relations. Therefore it becomes more and more improbable to develop a safe, sustainable and high quality product right from the beginning. In order to understand failures in complex system structures today's engineering industries need a generic approach that increases the understanding of systems, identifies critical components and considers the different levels of a system. It shall examine failures that cause system errors but also failures that limit system functions. Thus, it is necessary to model and simulate the causally failure chains and analyse over several system levels and elements with their dependencies. This leads to a better understanding of the whole picture of cause and effect. This research paper points out which requirements this new model-based approach has to fulfill and how it is possible to link quality and reliability methods to achieve an overall understanding and analysis of a complex system to assure high quality and sustainability.

“…Popular approaches (Adler, Domis, Höfig, Kemmann, Kuhn, Schwinn, and Trapp 2011) and (David, Idasiak, and Kratz 2009) have shown that UML as modeling language can be efficiently used with analysis and verification methods such as FMEA (failure mode and effect analysis), fault tree analysis (FTA), design walk through (Gvero, 2013), code-generation and many more. The drawback of UML, in terms of simulation to verify the system behavior is, that code-generation can only be done at a very late stage or even at the end of the design process, when all details are very well known.…”

The electrification of today's vehicles and the high amount of new assistance features imply more and more complex systems. The sensing and controlling of these systems is the work of the highly distributed and connected electronic control units. To keep pace with the fast growing automotive market, reusability of components and features is today the key to reduce costs and time-to-market. Especially when systems are safety-critical and demand reliability, new methods and tools are thus essential to support the reusability aspect in the development process. A model-based approach, in conjunction, moreover helps to communicate between different stakeholders, provides different views and serves as a central storage of information. Through applying reliability analysis and simulation-based verification methods on our hardware model and furthermore automatic generation of a first virtual prototype, we are able to reduce the tools involved, thus resulting in correctness, completeness and consistency of the entire system.

Hazard-driven realization views for Component Fault Trees

Traditionally, the preferred means of documentation used by safety engineers have been sheets-and text-based solutions. However, in the last decades, the introduction of model-driven engineering in conjunction with Component-Based Design has been influencing the way safety engineers perform their tasks; especially in the area of fault analysis, model-driven approaches have been developed aimed at coupling fault trees with architecture models. Doing this fosters communication between engineers, may reduce design effort, and makes artifacts easier to maintain and reuse. In this paper, we want to move forward in this direction and take another step in the modeling of Component Fault Trees in combination with the modeling of the architecture design. We propose a hazard-centric approach for the definition of multiple realization views for fault analysis using Component Fault Trees. The approach is composed of a modeling method and a tool solution. We illustrate our approach with a real-life example from the automotive industry.
