OBJECTIVE This study aimed to utilize failure modes and effects analysis (FMEA) to transform clinical insights into a risk mitigation plan for intrathecal (IT) drug delivery in pain management. METHODS The FMEA methodology, which has been used for quality improvement, was adapted to assess risks (i.e., failure modes) associated with IT therapy. Ten experienced pain physicians scored 37 failur...
این تحقیق در خصوص کاستی های fmea سنتی و معرفی روش جدیدی از fmea بر پایه تخمین هزینه فازی و مقادیر سودمندی میباشد که توسط این روش نوعی rpn جدید فازی تعریف میشود وسپس این rpn با استفاده از روش ahp گروهی و با استفاده از ایجاد یک پرسشنامه وزندهی میشود تا نوع جدیدی از تابع عضویت فازی برایrpn با تخصیص وزنهای مختلف برای هر یک از فاکتورهای شدت (severity) ، رخداد (ocurrance)و تشخیص (detection) بر ا...
Abstract Failure mode and effect analysis (FMEA) is a systematic approach for identifying potential failures before they occur, with the intent to minimize the risk associated with them. It has been widely used in the various manufacturing industries as a solution to reliability problems. As the importance of the service sector is increasing, however, it has been recently extended to some appli...
Constructability analysis and the resulting adjustments in facility design have a significant potential in improving cost effectiveness of construction projects. However, traditional constructability knowledge acquisition techniques are the key barrier to successful constructability improvement. A new approach to automated constructability lessons-learned documentation and constructability anal...
Conceptual design knowledge concerning with functions of products and phenomena unintended by designers is scattered around various forms such as the functional model and the FMEA sheet, which are dependent on engineering tasks. Aiming to promote sharing of such knowledge among designers, this paper proposes a knowledge transformation system from extended functional models to FMEA sheets based ...
In this report presents our experience with automating parts of the FMEA process using a model checker. As the case study a minepump control system is used, that prevents flooding in a mineshaft
Project management has been consolidated into organizations due to its high added value, allowing that project results are delivered on time, budget, scope and quality. This is specially important for ICT projects, for which innovation is usually present. For such, the correct resource allocation, and effective management require application of project management techniques and tools. In this s...
This paper proposes an integrated approach to identify, evaluate, and improve the potential failures in a service setting. This integrated approach combines FCS-FMEA, GRA and profitability theory for better prioritization of the service failures by considering cost as an important issue and using the profitability theory in a way that the corrective actions costs are taken into account. Conside...
Nowadays, improving and upgrading quality of products and services is one the main reason for outgoing the competitors and penetration into markets. This article is about the deficiency of the traditional FMEA, and introduces a new method based on estimated costs fuzzy FMEA and utility values. In the proposed method a new fuzzy RPN is defined. A pair wise comparison among Severity, Occurrence a...
Failure mode and effects analysis (FMEA) has been proven to be an effective methodology to improve system design reliability. However, the standard approach reveals some weaknesses when applied to wind turbine systems. The conventional criticality assessment method has been criticized as having many limitations such as the weighting of severity and detection factors. In this paper, we aim to ov...
