Classifier performance evaluation is an important step in designing diagnostic systems. The purposes of performing classifier performance evaluation include: 1) to select the best classifiers from the several candidate classifiers, 2) to verify that the classifier designed meets the design requirement, and 3) to identify the need for improvements in the classifier components. In order to effect...

Evaluating the sustainability risk level of public–private partnership (PPP) projects can reduce project risk incidents and achieve the sustainable development of the organization. However, the existing studies about PPP projects risk management mainly focus on exploring the impact of financial and revenue risks but ignore the sustainability risks, causing the concept of “sustainability” to be ...

There are four primary accident types at steel building construction (SC) projects: falls (tumbles), object falls, object collapse, and electrocution. Several systematic safety risk assessment approaches, such as fault tree analysis (FTA) and failure mode and effect criticality analysis (FMECA), have been used to evaluate safety risks at SC projects. However, these traditional methods ineffecti...

We are surrounded by ever more dependable systems, such us driving assistance systems from the automotive domain or life-supporting systems from the medical domain. Due to their increasing complexity, not only the development of but also the quality assurance for such systems are becoming increasingly difficult. They may cause various degrees of harm to their environment. Hence, in order to red...

The paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (FMEA). The approach is based on the ‘technique for order preference by similarity to ideal solution’ (TOPSIS). The priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...

The Forest Fire Fighting Vehicle (FFFV) is one of the most important pieces equipment in direct firefighting; therefore, its maintenance strategic to guarantee high levels reliability. history interventions essential support increase quality maintenance, namely with regard specificity each equipment, actual operating conditions. In absence previous information, it resort complementary tools tha...

OBJECTIVES Quantitative evaluation of safety after the implementation of a computerized provider order entry (CPOE) system, stratification of residual risks to drive future developments. DESIGN Comparative risk analysis of the drug prescription process before and after the implementation of CPOE system, according to the Failure Modes, Effects and Criticality Analysis (FMECA) method. MEASURE...

This paper provides an update to [1] on the developments associated with a Prognostics and Health Management (PHM) system design tool that integrates a model-based FMECA methodology with state-of-the-art system simulation directly linked to downstream Life Cycle Costs (LCC). This design tool will seek out recommended PHM system designs based on a cost function that accurately represents key LC...

Robots in hazardous environments must meet stringent requirements of both durability and reliability to be safe, as robust systems and efficient reliability techniques are critical to safe operation in these environments. Rosie, a large hydraulic robot designed for nuclear reactor decontamination and dismantlement, is a prime example of such a robot. The study discussed here uses a hydraulic te...
