The recommended phrase format is to use an"action verb"followed by a"noun"to describe a measurable function. 推荐的短语格式为:一个“行为动词”后加一个“名词”,表示可测量的功能。 修正: The recommended phrase format is to use anaction verbfollowed by anounto describe a measurable function. 推荐...
从可能的多因素原 因中找出主要原因; ─ 应用失效树分析(FTA)找出复杂系统的失效原因与机理; ─ 充分发挥小组的经验,采用头脑风暴法,对可能的原因进行归 纳分析; 24 Note: Don ' t take the working environment (such as Vibrating due to uneven, impact, changing of temperature, humidity, stive and ...

Agree with Inna, combining stat/math and prior scientifical knowledge is the key. But..in my opinion another limitation of the FMEA approach is – by definition – that it is an univariate (qualitative or semi-quantitative) tool. How is it possible to assign a correct risk ranking to pharma...
The FTA has been used to model pipeline failures, which is mapped using the BN model. Noisy-OR gate is then used to determine the conditional probability of the related nodes of the BN and thus the failure probability. The data relies on literature and expert knowledge. The study shows ...
Tableis removed from the Handbook 该表从手册中删除 Martin老师解读:删除“基于时间的失效预测值来评价DFMEA发生度”的评分表格,DFMEA更多基于定性分析的考虑,定量分析参考FMEDA、FTA。 打开网易新闻 查看精彩图片 打开网易新闻 查看精彩图片 章节F2.1 原文: ...

Tube hydroforming technology is widely used in the automotive industries due to its advantages such as weight reduction, increased strength, improved quality, and reduced tooling cost compared to conventional manufacturing technology. The hydroformed parts often have to be structurally joined at some poin...
At the same time, different professional backgrounds of experts may lead to different weights in modeling the evaluation. How to model the relative weight of an expert is an important problem. We propose an improved risk analysis method based on triangular fuzzy numbers, the negation of basic ...
