Software-intensive systems are characterized by an increasing number of features implementing complex functionalities. In many domains, these new functionalities perform more and more safety-critical tasks. To argue about the safety of such systems, Safety Cases are a proven technique that allows a systematic argumentation. Safety Cases may contain complex arguments that can be decomposed corre...

In the view of changing technologies in requirement engineering the RRS framework is being introduced [1] for early stage requirement defect identification [2] and mitigation [3] during software development process to make requirement specification reliable. With the use of RRS framework at early stage of SDLC, requirement defect identification and their proper mitigation has become cheaper tha...

failure relationship Figure 6: Fault tree for the failure plugged up of a Filter. Wifa supports a user mainly by providing comfortable access to FMEA cases. She or he can, for example, retrieve actions that have been taken for similar failure modes. 4.7 Completeness and Consistency of System Description The goal of a system description should be to include everything that is of practical releva...

Objective Using Failure Mode and Effects Analysis (FMEA) as an example quality improvement approach, our objective was to evaluate whether secondary use of orders, forms, and notes recorded by the electronic health record (EHR) during daily practice can enhance the accuracy of process maps used to guide improvement. We examined discrepancies between expected and observed activities and individu...

The comprehensive on-board diagnosis of faults in many aerospace and other engineered systems requires real time execution using limited computational resources, and must also provide verifiable behaviour. This paper shows how a diagnostic system satisfying these requirements can be automatically generated from the model based simulation used to produce an automated Failure Modes and Effect Ana...

In this report we present our experience with the tool-supported FMEA process using Behavior Trees as a modeling notation, the failure mode injection technique, and a model checker as analysis tool. The approach is based on the work in [3]. As a case study we use the industrial press [1], which is similar to the one described by [2, 3]. The report describes in detail how we derive the Behavior ...

Abstract Failure mode and effect analysis (FMEA) is a systematic approach for identifying potential failures before they occur, with the intent to minimize the risk associated with them. It has been widely used in the various manufacturing industries as a solution to reliability problems. As the importance of the service sector is increasing, however, it has been recently extended to some appli...
