Usage of Case-based Reasoning in FMEA-driven Software

2014

Abstract Failure Mode and Effect Analysis (FMEA) is among the most widely used safety analysis procedures in the various industries. The procedure is generally perceived as complex and time-consuming, hindering an effective reuse of previous knowledge. In this paper we present an innovative usage of knowledge system into FMEA process using the Case-based reasoning to reduce the time and effort associated with this analysis. Knowledge system is built to serve multi-projects work that nowadays are in place in any manufacturing or services provider, and knowledge must be retained and reused at the company level and not only at project level. Collaboration is assured trough web-based GUI that s…

Introducción de nuevos equipos e implementación de técnicas especiales aplicadas al tratamiento de lesiones de piel en radioterapia

2017

En el presente trabajo se ha realizado un análisis de riesgo de dos modalidades de tratamiento radioterápico de piel, la braquiterapia electrónica (eBT) y la irradiación total de la piel con electrones (TSEI). Paralelamente, se ha hecho un estudio de blindajes para la unidad de tratamiento de eBT. El trabajo se ha dividido en 4 capítulos. El capítulo 1 resume las principales ventajas de las técnicas de tratamiento del cáncer de piel no melanoma que se utilizan actualmente en radioterapia, contextualizando la implantación de la eBT. También se expone el tratamiento de la micosis fungoide en radioterapia, enfermedad que afecta a toda la superficie corporal del paciente, para la cual, la TSEI …

Safety studies of a hydrogen refuelling station: Determination of the occurrence frequency of the accidental scenarios

2009

At present, the hydrogen vehicles technology appears to have future Prospective for reduction in greenhouse gas emissions. Nevertheless, the development of such a technology requires appropriate infrastructures for production, Storage and refuelling stages in a refuelling station. This one presents safety challenges due to the hydrogen chemicophysical characteristics. So, to avoid hazards, it is necessary to implement safety practices that, if early adopted in the development of a fuelling station project, can allow very low impact, safety being incorporated in the project itself. However, a drawback is the not sufficient experience and the scarcity of the relevant data collection. To deepe…

Focus on failure avoidance and risk reduction through Variation Mode and Effect Analysis

2009

Variation Mode and Effect Analysis (VMEA) is a quality improvement tool initially thought to help product development engineers focusing on variation. The method was inspired by the wide use of Failure Mode and Effect Analysis (FMEA) in business and industry and the increased attention on robust design. However, FMEA is based on the concept of failure while VMEA is developed on the concept of variation, i.e. it implies a step further toward the awareness of variation and its implications in terms of risk and failures. VMEA helps identifying, scrutinizing and measuring the sources of variation and the way they channel through and impact on important characteristics of the system under study.…

Failure mode and effects analysis of skin electronic brachytherapy using Esteya® unit

2016

Purpose: Esteya® (Nucletron, an Elekta company, Elekta AB, Stockholm, Sweden) is an electronic brachytherapy device used for skin cancer lesion treatment. In order to establish an adequate level of quality of treatment, a risk analysis of the Esteya treatment process has been done, following the methodology proposed by the TG-100 guidelines of the American Association of Physicists in Medicine (AAPM). Material and methods: A multidisciplinary team familiar with the treatment process was formed. This team developed a process map (PM) outlining the stages, through which a patient passed when subjected to the Esteya treatment. They identified potential failure modes (FM) and each individual FM…
