设备维修是确保设备正常运行的主要手段,是企业的一项重要的管理工作,也是一项主要的生产费用支出。据有关资料表明,我国固定资产中60%以上为机电设备,机电系统的费用支出已占成本的40%以上;另外,各类事故及重大火灾在很大程度上是由于机电原因引起的。正是由于认识到设备维修的重要性和复杂性,许多企业借助于计算机和专家系统等先进手段,采用以可靠性为中心预防维修策略,使设备在一个相对延长的寿命周期内可靠地工作,并尽可能地避免了无效维修。
Equipment maintenance is to ensure the normal operation of the main means of equipment is an important business management, but also a major production costs. According to relevant information, more than 60% of fixed assets in China are mechanical and electrical equipment, and electromechanical systems have accounted for over 40% of the cost. In addition, all kinds of accidents and major fires are caused in large part by mechanical and electrical reasons. It is in recognition of the importance and complexity of equipment maintenance that many enterprises rely on reliability-centric preventive maintenance strategies with advanced tools such as computers and expert systems to reliably operate their equipment over a relatively extended life cycle, And as far as possible to avoid invalid maintenance.
