1) replacement policy
更换策略
1.
Under the conditions that the repairman vacation time is respectively random variable and constant,replacement policy is considered based on the working.
在修理工休假时间分别为随机变量和定长的情况下,选取系统的总工作时间T和故障维修次数N为更换策略,以长期运行单位时间内的平均停机时间为目标函数,通过更新过程和几何过程理论建立数学模型,导出了目标函数的解析表达式。
2.
Assume that the system after repair is not "as good as new", by using geometric processes we consider a replacement policy N based on the f.
在该系统为”修复非新”时,我们利用几何过程考虑了以系统的故障次数N为更换策略,以长期运行单位时间内的期望费用为目标函数,通过目标函数最小化确定了最优更换策略。
3.
An optimal replacement policy for series repairable system is studied assuming that the component after repair is not "as good as new" by using the geometric process model.
在假定故障部件不能"修复如新"的条件下,基于几何过程模型研究可修串联系统的最优更换策略。
2) replacement policy N
更换策略N
1.
A replacement policy N is adopted by which the system will be replaced by an identical new one at the time following the Nth failure.
作者采用更换策略N,即当且仅当系统已经失效N次时用一个全新的系统更换,然后得到了系统长期运行下的平均费用的表达式,并且找到了最优更换策略N*的解析表达式,最后给出了一个数值实例。
3) Strategy of roller replacement
轧辊更换策略
4) age replacement policy
工龄更换策略
1.
Based on the concepts of potential fault and delay time,the age replacement policy and spot checking and regularly repairing policy was researched under the condition that the initial defect time and delay time distribution models were known.
在已知设备初始时间、延迟时间分布规律的基础上,由潜在故障和延迟时间的概念出发,分别研究了工龄更换策略和点检定修策略的费用模型、功能故障风险模型,并通过算例进行了两种策略的比较分析。
5) repair and replacement policy
维修更换策略
1.
This paper studies the reliability, preventive repair and replacement policy for a repairable system consisting of one component and one repairman and with no preventive repair time.
研究了具有预防维修的单部件一个修理工的可修系统的维修更换策略。
6) chip changing tactics
监控片更换策略
1.
A problem about the chip changing tactics during the depositing process of multiplayer optical coatings that monitoring by separating control technique was investigated.
分析了不同的监控片更换策略对所淀积薄膜光学特性的影响,得出了监控片的更换策略也是决定所镀制光学薄膜成功与否的关键因素之一的结论。
补充资料：更换彩壳
随着手机的逐渐普及，人们对手机的要求已不单单是要求其内在的质量或性能，对外观的追求也日益增强，单一的手机外形或外壳已不能满足要求个性的手机用户的需求。所以手机更换彩壳的功能被厂家广泛应用。
更换彩壳顾名思义即手机可以根据用户个人爱好或需求随意更换手机原有外壳。目前，更换手机外壳主要有三种类型：前后壳均可更换；仅能更换前壳；仅能更换前壳上一部分面板。
