The Unified Modeling Language (UML) is the de-facto standard modeling language for the development of software with broad ranges of applications. It supports for modeling a software at different stages during its development: requirement analysis, design and implementation. The use of UML encourages software developers to devote more effort on requirement analysis and modeling to produce better...

Reliability is an important performance index of a modern power electronics converter. The failure modes and effect analysis (FMEA) is one the mostly used techniques to evaluate or possibly improve the reliability of a power electronic system. This is one of the key challenges in electronics converters for vehicle industry. The project aim is to increase the reliability of a 3.3 kW on-board veh...

In the past years, the scale of software is growing quickly as more and more organizations begin to deploy their business on Internet. As a result, requirement analysis becomes a challenging issue and conventional approaches might significantly increase the costs of software development. Therefore, automatic requirement analysis techniques have attract more and more attentions, which allows for...

The paper presents how CSP and the associated tool FDR are used to support FMEA of a software intensive system. The paper explains the basic steps of our approach (formal specification, systematic fault identification, fault injection experiments and follow-up) and gives some results related to the application of this method to the industrial case study, a railway signalling system that is pres...

Failure mode and effects analysis (FMEA) is one of the well-known techniques of quality management that is used for continuous improvements in product or process designs. While applying this technique, determining the risk priority numbers, which indicate the levels of risks associated with potential problems, is of prime importance for the success of application. These numbers are generally at...

This article aims to show few advanced approach method for improving Failure Mode and Effect Analysis (FMEA). The possible failure situations in the system design are investigated separately considered a Hierarchical FMEA worksheet form. authors propose three different methodological methods based on hybridized fuzzy logic FMEA.

A thorough requirements analysis is indispensable for developing and implementing safety-critical software systems such as nuclear power plant (NPP) software systems because a single error in the requirements can generate serious software faults. However, it is very difficult to completely analyze system requirements. In this paper, an effective technique for the software requirements analysis ...

Objective: The objective of this project was to evaluate the risks associated with converting a paper-based pediatric chemotherapy ordering process to a fully electronic system. Methods: Formal process redesign and systems analysis, primarily through Failure Mode and Effects Analysis (FMEA), was used to evaluate the current, paper-based chemotherapy medications process. A commercial software sy...
