Failure modes and effects analysis (FMEA) has been used to identify the critical risk events and predict a system failure to avoid or reduce the potential failure modes and their effect on operations. The risk priority number (RPN) is the classical method to evaluate the risk of failure in conventional FMEA. RPN, which ranges from 1 to 1000, is a mathematical product of three parameters—severit...

پل­ها با هر شکل سازه­ای و با هر نوع مصالحی که ساخته شوند، دیر یا زود اثرات فرسودگی در آنها ظاهر می­شود. در نوع و میزان این فرسودگی­ها و میزان گسترش آنها عوامل متعددی تاثیرگذار می­باشند. هر یک از این عوامل چنانچه مورد توجه و رسیدگی قرار نگیرند، منجر به کاهش عمر مفید سازه خواهند شد. در این پژوهش پس از بررسی­های انجام شده با استفاده از روش FMEA-FUZZY، مشخص ش...

Medical product development (MPD) process is highly multidisciplinary in nature, which increases the complexity and the associated risks. Managing the risks during MPD process is very crucial. The objective of this research is to explore risks during MPD in a dental product manufacturing company and propose a model for risk mitigation during MPD process to minimize failure events. A case study ...

In the development of safety-critical systems, it is important to perform failure modes and effects analysis (FMEA) identify potential failures. However, traditional FMEA activities tend be considered difficult time-consuming tasks. To compensate for difficulty task, various types tools are used increase quality effectiveness reports. This paper explains an automatic tool that integrates model-...

Objective Using Failure Mode and Effects Analysis (FMEA) as an example quality improvement approach, our objective was to evaluate whether secondary use of orders, forms, and notes recorded by the electronic health record (EHR) during daily practice can enhance the accuracy of process maps used to guide improvement. We examined discrepancies between expected and observed activities and individu...
