Requirement eliciting, organizing, developing and managing are most important activities in the implementation of software systems. Changes of requirements are inevitable. But, too many changes of requirements might fail software projects. Thus, the stability of the software requirements of a project is critical to the software development success. However, there are no published studies on sof...

Some results of the implementation of a new support tool for automated hazard analysis are presented in this paper. We describe in detail the further progresses on the application of intelligent systems to the hazard analysis and especially to the HAZOP and FMEA analysis. A previously developed program, that allows the automatic generation of the report of the HAZOP analysis as regards the dete...

The Failure Mode and Effect Analysis (FMEA) is often used to improve a system’s reliability. This paper proposes new approach that aims overcome the most critical defects of traditional FMEA. methodology combines Entropy Best Worst Method (BWM) with EDAS System Dynamics, FMECA: EN-B-ED Dynamic FMECA. main innovation point proposed work presence an unknown factor (Cost) allows obtain objective w...

FMEA has been used for several years and proved its efficiency for system’s risk analysis due to failures. Risk priority number found in FMEA is used to rank failure modes that may occur in a system. There are some guidelines in the literature to assign the values of FMEA components known as Severity, Occurrence and Detection. This paper propose a method to assign the value for occurrence in mo...

This paper describes how the effects of possible component failures on an electrical system can be predicted through simulation of the correct behavior of the system, and repeated simulation of versions of the system containing faulty components. The results of such simulation are useful both for failure mode and effects analysis (FMEA), and for diagnosis. Such results have been used commercial...

BACKGROUND Failure Mode and Effect Analysis (FMEA) is a method used to assess the risk of failures and harms to patients during the medical process and to identify the associated clinical issues. The aim of this study was to conduct an assessment of blood transfusion process in a teaching general hospital, using FMEA as the method. METHODS A structured FMEA was recruited in our study performe...

Failure Mode and Effect Analysis (FMEA) is one of the well-known techniques of quality management that is used for continuous improvement in product or process design. One important issue of FMEA is the determination of the risk priorities of failure modes. The purpose of this paper is to compare three different methods for prioritizing failure modes in a process FMEA study. These methods are t...

One of the key pillars of any operating system is its proper software performance. Software failure can have dangerous effects and consequences and can lead to adverse and undesirable events in the design or use phases. The goal of this study is to identify and evaluate the most significant software risks based on the FMEA indices with respect to reduce the risk level by means of experts’ opini...
