继80年代大力推广应用预知维修方式之后,进入90年代以来,美国工业界探讨维修体制及设备状态监测与故障诊断技术方面的活动十分活跃。在国际国内商业竞争日益激烈的形势下,许多企业在总结自己经验的基础上纷纷提出要建立一个世界水平的设备维修方式来降低成本,提高竞争力。如著名的3M公司的录像带工厂在1988年开始实行预知维修时,录像带每盘零售价为28.95美元,由于包括韩国和中国在内的太平洋周边地区国家的竟争,现在每盘零售价已被迫降低为2美元。技术含量如此高的产品要把成本降到如此低廉确非易事。因而降低维修成本成为该厂重要出
Following the vigorous promotion and application of predictive maintenance methods in the 1980s, since the 1990s, the U.S. industry has been active in discussing maintenance system and equipment condition monitoring and fault diagnosis technologies. Under the increasingly fierce international and domestic commercial competition, many companies have proposed to establish a world-class equipment maintenance method based on their own experience to reduce costs and improve competitiveness. For example, when the well-known 3M company’s video tape factory began to implement predictive maintenance in 1988, the retail price of the video tape was $28.95. The retail price in each of the regions around the Pacific, including South Korea and China, has now been forced to compete. Reduced to 2 dollars. It is no easy task to reduce the cost of such a high-tech product. Therefore, reducing maintenance costs becomes an important issue for the plant.
