摘要
建立韧性供应链要求有效防控地震等自然灾害可能给供应链关键环节带来的风险。随着大数据、物联网、人工智能等技术普及,精密电子元件的生产设备成为微电子产业供应链的关键且昂贵环节。合理评价其在地震作用下的功能损失是微电子产业供应链地震风险防控的重要基础。该文以某精密元件生产厂为研究对象,利用其某型精密电子元件生产设备在2014—2023年多次远场地震中的功能损失事件及其周边地震动数据,建立面向精密生产的功能损失模型和功能损失等级评价方法。结果表明,与其他地震动强度指标相比,中心频率为0.4 Hz的1/3倍频程均方根速度V_(RMS)(0.4 Hz)与影响率的相关性最强,拟合的功能损失曲线质量最高。当该精密元件生产厂周边的地面运动的V_(RMS)(0.4 Hz)仅约为12 mm/s时,即可能严重影响精密生产设备的正常功能。
Building resilient supply chains requires effective prevention and control of the risks that natural disasters,such as earthquakes,may bring to key nodes in the supply chain.With the increasing popularization of the application of big data,Internet of Things,artificial intelligence and other technologies,the manufacture equipment of precision electronic components(hereinafter referred to as precision equipment)has become the key link in the supply chain of the microelectronics industry,and is also the most expensive component.The reasonable assessment of its functional loss is an important basis for the prevention of the seismic risk of the supply chain of the microelectronics industry.By taking a precision manufacture plant as the research object,and using the events in which its certain precision equipment suffered functional loss in far-field earthquakes from 2014 to 2023 and the seismic ground motion data obtained nearby,the precision-manufacture-oriented functional loss model and assessment method of loss levels are established.The results show that,compared with other ground motion intensity measures,1/3-octave root-mean-square velocity with a center frequency of 0.4 Hz(V_(RMS)(0.4 Hz))has the strongest correlation with the damage rate,and the functional loss curves based on it are fitted with the highest quality.When V_(RMS)(0.4 Hz)of the ground motion around the precision component manufacturing plant is only about 12 mm/s,it is possible to affect the normal function of the precision manufacture equipment at a serious level.
