Unreliable failure detectors, proposed by Chandra and Toueg [2], are mechanisms that provide information about process failures. In [2], eight classes of failure detectors were defined, depending on how accurate this information is, and an algorithm implementing a failure detector of one of these classes in a partially synchronous system was presented. This algorithm is based on all-to-all comm...

The failure mode and effect analysis (FMEA) approach was used to assess the potential risks for patients during the delivery of tomotherapy treatments. This study, which completed a previous investigation recently performed on the tomotherapy pretreatment phases, enabled the delineation of the delivery process tree and the identification of 30 failure modes, 9 of which were judged to be of part...

This paper argues that software engineering should not overlook the lessons learned by other engineering disciplines with longer established histories. As software engineering evolves it should focus not only on application functionality but also on mature engineering concepts such as reliability, dependability, safety, failure mode analysis, and maintenance. Software is rapidly approaching the...

a r t i c l e i n f o Keywords: Failure mode and effects analysis Data envelopment analysis Overall risks Risk priority ranking Failure mode and effects analysis (FMEA) is a method that examines potential failures in products or processes and has been used in many quality management systems. One important issue of FMEA is the determination of the risk priorities of failure modes. In this paper ...

The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely tedious for an engineer to perform, as well as being error-prone. This paper presents the implementation of a novel method for automating code-level software FMEA based on treat...

Communicating failure mode information during design and manufacturing is a crucial task for failure prevention. Most processes use Failure Modes and Effects types of analyses, as well as prior knowledge and experience, to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and information i...

Quality and reliability of product and manufacturing process are the critical factors to the product development. However, to ensure good quality and reliability of the product and to predict any inadequacies of the product, an efficient quality system must be established at the earliest stage of the product development process. Failure Mode and Effect Analysis (FMEA) is a popular quality tool ...

Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...

This paper introduces a new method for safety analysis called HiPHOPS (Hierarchically Performed Hazard Origin and Propagation Studies). HiP-HOPS originates from a number of classical techniques such as Functional Failure Analysis, Failure Mode and Effects Analysis and Fault Tree Analysis. However, it extends, automates and integrates these techniques in order to address some of the problems cur...

The need to establish power plants to supply the required electricity of the country has been rising due to increasing demand levels as well as the lack of governmental resources. Furthermore, the available traditional attitude in performing and conducting power plant projects has made government seek a modern attitude. This paper tries to use the topics that have been employed in automotive in...
