This paper proposes a method of analysis for evaluating failure detectors. The method can be applied to compare the performance of failure detectors in a given environment. Through a cost analysis approach, this method creates a cost metric, averagelost, which might tackle with comparing two failure detectors. Through the consequent experiment, we conclude that the value of a failure detector d...

This paper presents a ‘Lexicographic’ Goal Programming (LGP) approach to define the best strategies for the maintenance of critical centrifugal pumps in an oil refinery. For each pump failure mode, the model allows to take into account the maintenance policy burden in terms of inspection or repair and in terms of the manpower involved, linking them to efficiency-risk aspects quantified as in FM...

* This work is supported by the Commission of the European Union (Project no. G3RD CT199-00058) Abstract The growing importance of on-board diagnosis for automobiles demands for a close integration of diagnostic tasks in the entire design process. This report describes work carried out to date within the European project „Integrated Design Process for onboard Diagnosis„ (IDD). It presents an an...

Time pressure and quality issues bring new challenges for developing web-based systems. The ability to analyze quality early in the development lifecycle is crucial. Among the techniques suggested by the literature, few of them actually support early quality activities when little information about the system is available. We take robustness as a critically important quality attribute, and pres...

A new method of diagnosing risks in product-innovation projects is introduced in the paper. The method is an improvement on existing risk methods used on product-innovation projects, such as potential problem analysis and failure mode and effects analysis. Technological, organizational and commercial risks are identified and assessed on an individual basis. These risks are mapped in a risk topo...

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...

The development of safety critical systems becomes even harder since the complexity of these systems grows continuously. Moreover, this kind of process involves the use of powerful design methods and precise reliability techniques that utilize dissimilar models and construction policy. In this article we propose a method to unify and enhance this process by linking functional design phase using...

It has been suggested that goal-directed actions performed under full vision are immune to certain visual illusions, while movements relying on perception-based visual information are deceived by them (Milner & Goodale, 1995). Consequently, pointing movements should be deceived by visual illusions when a delay is introduced (memory demands) or when antipointing (spatial imagery) is required. In...

Failure mode and effects analysis (FMEA) has been extensively used for examining potential failures in products, processes, designs and services. An important issue of FMEA is the determination of risk priorities of the failure modes that have been identified. The traditional FMEA determines the risk priorities of failure modes using the so-called risk priority numbers (RPNs), which require the...
