Traditional methods for the assessment of software safety suffer from poor integration (from methodological, operational and semantic points of view) both with each other and with the rest of the development lifecycle of safety-critical systems. Our goal is to develop a set of methods and tools which address these weaknesses, and this paper describes our current research into these areas. We de...

1. Introduction As the types of defects that are causing small leakage currents are more and more difficult to find with decreasing feature size, more advanced analysis strategies have to be developed to meet reliability demands. A method based on a delta Iddq test has been developed to sort out parts with potential reliability issues. Those parts are fully functional, but show small Iddq varia...

Safety critical systems are those systems whose failure could result in loss of life, significant properityda mage, or damage to the environment. Brake-by-wire (BBW) technology in automotive industry is the ability to contr ol brakes through electrical means. It can be designed to supplement ordinary service brakes or it can be a standalone brake system. The increasing usage of brake-by-wire sy...

Background: Healthcare statistics, issued by various international organizations, show that medical errors in health centers impose high costs on patients and hospitals increase the rates of morbidity mortality around world. Due to potential risks cardiovascular diseases, occurrence any can potentially endanger patients’ lives incur them, as well hospitals. On other hand, anesthesia is one prio...

Im Rahmen der präventiven Qualitätsmanagement-Methode FMEA (Failure Mode and Effects Analysis) wird jedes Risikoelement durch die Parameter Bedeutung (B), Auftretenswahrscheinlichkeit (A) und Entdeckungswahrscheinlichkeit (E) charakterisiert. Um die Risikoelemente rangieren zu können, wird für jedes Risikoelement eine Risikoprioritätszahl (RPZ) berechnet. Für diese Berechnung existieren verschi...

Der Beitrag stellt ein softwaregestütztes Modell vor, in dem methodische, softwaretechnische und organisatorische Ansätze zu einem Werkzeug für das präventive Risikomanagement zusammengeführt sind. Das Modell verknüpft folgende softwaregestützte Methoden mit dem Risikomanagementprozess: 1. Risikobeurteilung: Einsatz der softwaregestützten FMEA (FehlerMöglichkeits und Einfluss-Analyse) und weite...

This paper considers the endogenous formation of an institution to provide a public good. If the institution governs only its members, players have an incentive to free ride on the institution formation of others and the social dilemma is simply shifted to a higher level. Addressing this second-order social dilemma, we study the effectiveness of three different minimum participation requirement...

The overall dependability of an interactive system is the one of its weakest component which is usually its user interface. The presented approach integrates techniques from the dependable computing field and elements of user-centred design to provide a wider coverage of possible faults. Risk analysis and fault tolerance techniques are used in combination with task analysis and modelling to des...

This document summarizes the suitable design strategies that have been followed (and exposed in the contractual deliverable 57) in order to meet the reliability and availability specifications for the XADS accelerator. The document describes also how these strategies can be applied in the different components, and how iterations can lead to reliability improvements. The Failure Mode and Effect ...

BACKGROUND Prospective Hazard Analysis techniques such as Healthcare Failure Modes and Effects Analysis (HFMEA) and Structured What If Technique (SWIFT) have the potential to increase safety by identifying risks before an adverse event occurs. Published accounts of their application in healthcare have identified benefits, but the reliability of some methods has been found to be low. The aim of ...
