  • 有人了解国外注册工程师的工作要求、资格认证和待遇水平吗?

    目前在北京,上海,深圳可以进行CRE考试,2008年CRE考试每年有2次考试,3月和7月。如果你的能力够的话可以尝试做做CRE题目。目前在美国地区得到广泛应用,在我国台湾和香港地区也有很多大公司要求CRE,此外,像国外Dell,Intel,hp,Sunmicro等公司有要求ODM可靠性工程师取得CRE资格证书。一般来说取得CRE证书后比没有取得证书薪资方面回增加2~3倍,目前国内正在逐步开始CRE的培训。 同时根据ASQ的要求,考试人员对各种不同学历的人都有要求。 ReliabilityEngineerCertification[b]StudyGuide[/b] Testyourpreparednessfortheexamusingthisstudyguide.Answersareattheend.

    CRE是对可靠性工程师整体水平的评估,它不是对可靠性试验能力或理论水平的一种要求.换句话说一个在知名企业干了10年以上对产品试验了如指掌,也不一定可以取得,它主要是去检验一个工程师面对可靠性方面的一些问题和各种问题的应对能力评估,比如它会问到一些可靠性方面的,testplan如何制定?可靠性工程师在公司是扮演什么角色等等问题.附件有一份CRE的BOK.里面有许多关于CRE工程师提问的问题。 知识大纲(BOK)下载:[url] 链接[/url]
