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 aim of this paper was the application of the failure mode and effects analysis (FMEA) approach to assess the risks for patients undergoing radiotherapy treatments performed by means of a helical tomotherapy unit. FMEA was applied to the preplanning imaging, volume determination, and treatment planning stages of the tomotherapy process and consisted of three steps: 1) identification of the i...

background and objectives: surgical cancelation is a significant source of time and resource waste, patientsafety risk, and stress for patients and their families. in this study, a risk management-based approach is developed to prioritize factors contributing to surgical cancellation. methods: factors leading to surgical cancellation were comprehensively classified based on literature review.a...

Abstract Failure mode and effect analysis (FMEA) is a risk tool widely used in the manufacturing industry. However, traditional FMEA has limitations such as inability to deal with uncertain failure data including subjective evaluations of experts, absence weight values parameters, not considering conditionality between events. In this paper, we propose holistic overcome these limitations. The p...

Palm Oil Mill is an industry that processes Fresh Fruit Bunches into Crude Oil. The processing supported by the use of several production machines, one them a sterilizer machine works to boil TBS. Damage can reduce level productivity. To overcome occurrence such damage, it necessary analyze damage occurred. analysis was carried out using Failure Mode and Effect Analysis Caused Diagram approache...

FMEA is a systematic process for indentifying potential design or process failure before they occur. The aim is to eliminate them or minimize the risk associated with them. The method is a procedure to analize failure modes and clasified them by severity. It is a systematic process for identifying potential failures before they occur with the intent to eliminate them or minimize the risk associ...

intrbackground and objectives: good medical nutrition therapy (mnt) is crucial to inpatients' health and treatment, and is part of routine hospital cares. surgery ward is a highly danger-prone section in any hospital. the present study was conducted for a proactive risk analysis of nutrition and food distribution in mashhad qaem hospital’ women’s surgery ward in 2013 through health care fa...

Paper aims This paper proposes the combination of quality tool FMEA (Failure Modes Effects and Analysis) with DHFS (Dual Hesitant Fuzzy sets) technique to process judgements hesitation hence conduct prioritization failure modes considering a group decision making problem. Originality There are no studies that combine technique. Research method Firstly, this presents review current literature. T...

In any organization, the importance of failuremanagement cannot bementionedby a single word. However,most failure analysis is dominated by themanufacturing sector, despite the increasing importance of the service sector. In response, this paper proposes a systematic approach for identifying and evaluating potential failures using a service-specific failure mode and effect analysis (service-spec...
