针对目前计算机维护还处在先故障后维修的亡羊补牢式的维修方式，导致即使故障修复，但损失已酿的结果，提出了建立有预测功能的 FMEA 故障模型解决方案。先对计算机硬件设备故障进行分类，建立 FMEA 故障模型。然后，综合各部件故障数据生成 FMEA 分析表，通过分析表了解各故障部件之间的联系，预测故障机率，从而得出可能出现故障的预测结果，进而采取相应措施消除故障隐患，同时可以对易损部位做充分准备。通过分析研究和实际应用表明，对计算机硬件设备建立 FMEA 故障模型，可大幅度降低故障发生率，且对不可规避的故障也可以有准备地最快最简便的排除，减少损失。
針對目前計算機維護還處在先故障後維脩的亡羊補牢式的維脩方式，導緻即使故障脩複，但損失已釀的結果，提齣瞭建立有預測功能的 FMEA 故障模型解決方案。先對計算機硬件設備故障進行分類，建立 FMEA 故障模型。然後，綜閤各部件故障數據生成 FMEA 分析錶，通過分析錶瞭解各故障部件之間的聯繫，預測故障機率，從而得齣可能齣現故障的預測結果，進而採取相應措施消除故障隱患，同時可以對易損部位做充分準備。通過分析研究和實際應用錶明，對計算機硬件設備建立 FMEA 故障模型，可大幅度降低故障髮生率，且對不可規避的故障也可以有準備地最快最簡便的排除，減少損失。

Now,computer maintenance mode is still in the primary step,maintenance performed after the fault occurs,which results in the loss even if the fault has been repaired.A solution of FMEA fault model predictive capabilities is proposed in this paper.First computer hardware equipment failure is classified to establish FMEA fault model.Then,FMEA analysis table is generated by integrating failure data of each component to understand the relationship between the failure parts and predict the probability of failure.The predicted result for the parts to be failed is obtained to take the appropriate measures to eliminate hidden faults and fully prepare the vulnerable parts.The research and application show that FMEA fault model,made for computer hardware,can significantly reduce failure rate and fully perform preparation for troubleshooting the failures and reducing losses.
