目前,许多企业在确定适合自身情况的设备维修方式时,通常是凭主观感觉和经验,或以设备的购置费高低、该设备在企业生产中所处的重要程度等判断,而较少在理论上研究。本文仅从可靠性基本理论方面,在预防维修和事后维修权衡方面做一初步探讨,以确定哪些设备应采取预防维修,哪些设备应采取事后维修。一、权衡的模型建立设某设备中有一易损零件,该零件的可靠度为R(t),在设备使用过程中对维修形式就存在着一个决 At present, many enterprises in the determination of their own equipment maintenance mode, usually by subjective feeling and experience, or equipment purchase costs, the importance of the equipment in the production of enterprises to judge, but less in theory On the study. This article only from the basic theory of reliability, preventive maintenance and after-sales service trade-offs to make a preliminary study to determine which equipment should be preventive maintenance, which equipment should be taken after maintenance. First, the trade-off model established Let a device in a vulnerable parts, the reliability of the part R (t), the use of equipment in the maintenance of the form there is a resolution
