什么是EAM？EAM，英文全称Enterprise Asset Management，中文全称企业资产管理系统，是面向资产密集型企业的信息化、制造业信息化、企业信息化解决方案的统称。EAM是指在资产密集型产业里通过信息化手段，合理安排维修计划及相关资源与活动。EAM以提高资产可利用率为目标来实现增效，通过优化安排维修资源来实现降本，从而提升企业经济效益及增强企业市场竞争力。EAM的前身为CMMS（Computerized Maintenance Management System：计算机化的设备维护管理系统）。
18世纪第一次产业革命至19世纪
EAM系统在此时的作用是当设备故障或失效时非计划性维修。
19世纪至20世纪30年代
EAM系统在此时的作用是定期点检及早期维护，在这阶段，EAM系统包括计划检修和定期检修。其中计划检修是以设备修理周期、结构和复杂度系数等一套定额标准为依据，采用强制预修理，即按计划周期图表对设备修理。EAM系统中定期维修是以设备日常点检和定期点检为基础，依据点检发现缺陷，及时编制检修计划，以便对设备修理、排除隐患，恢复设备的性能。
20世纪40年代至80年代
EAM系统在这时的作用是经济检修，此后EAM资产管理系统的功能升级为全员维修。EAM系统在这时的功能包含事后维修(BM)、预防维修(PM)、改进维修(CM)和维修预防(MP)。EAM系统在这时的特点是设备现代化、管理现代化，EAM系统在这时开始拥有设备寿命周期评价，在此阶段，也产生了设备综合工程学、维修工程学等学科，EAM系统维修组织集中化发展，维修活动全员参与。
20世纪80年代至今
EAM系统在这时的功能是依据对设备运行状态监测、预测和判别做出维修决策。维修决策的产生条件是从科学技术领域分化、综合发展，EAM系统对设备管理，不仅有各种理论支持，还以监测和诊断的科学技术手段为基础。在这一阶段，设备管理也向着社会化、专业化和国际化发展，运行人员在此时开始参与检修。

What is EAM? EAM, the English full name of Enterprise Asset Management, the Chinese full name of enterprise asset management system, is a general term for information technology, manufacturing information technology and enterprise information technology solutions for asset-intensive enterprises. EAM refers to the reasonable arrangement of maintenance plans and related resources and activities in asset-intensive industries by means of information technology. EAM aims to improve the utilization rate of assets to achieve efficiency, optimize the arrangement of maintenance resources to achieve cost reduction, so as to enhance the economic benefits of enterprises and enhance the market competitiveness of enterprises. EAM is formerly known as CMMS (Computerized Maintenance Management System: Equipment Maintenance Management System). Digital transformation network szhzxw.cn
18th century The first industrial revolution to the 19th century
The role of the EAM system at this time is to perform unscheduled maintenance when the equipment fails or fails.
Digital transformation Network from the 19th century to the 1930s
The role of the EAM system at this time is to periodically check and early maintenance, in this stage, the EAM system includes scheduled maintenance and periodic maintenance. The planned maintenance is based on a set of standard standards such as equipment repair cycle, structure and complexity coefficient, and adopts compulsory pre-repair, that is, equipment repair according to the planned cycle chart. In the EAM system, regular maintenance is based on the daily spot check and regular spot check of the equipment. According to the spot check, defects are found, and maintenance plans are prepared in time to repair the equipment, eliminate hidden dangers, and restore the performance of the equipment.
Digital transformation Network from 1940s to 1980s
The role of the EAM system at this time was economic maintenance, and since then the function of the EAM asset management system has been upgraded to full maintenance. The functions of the EAM system at this time include post maintenance (BM), preventive maintenance (PM), improved maintenance (CM), and maintenance prevention (MP). At this time, EAM system was characterized by equipment modernization and management modernization. And EAM system began to have equipment life cycle evaluation. At this stage, comprehensive equipment engineering, maintenance engineering and other disciplines were also produced. And the maintenance organization of EAM system was centralized and developed, and maintenance activities were fully participated.
1980s to the present digital transformation network
The function of the EAM system at this time is to make maintenance decisions based on the monitoring, forecasting and discriminating of equipment operating conditions. The condition of maintenance decision is differentiated and comprehensive development from the field of science and technology. EAM system not only has various theoretical support for equipment management. But also is based on scientific and technological means of monitoring and diagnosis. At this stage, equipment management is also becoming social, professional and international. And operators begin to participate in maintenance at this time.
