Method for automatically generating engine failure rate analysis report

The invention discloses a method for automatically generating an engine failure rate analysis report. The method comprises the following steps: step 1, defining quality indexes; step 2, extracting and marking data; and step 3, generating a fault rate report, and forming the fault rate report according to the engine debugging fault rates of different product batches, the engine class I and class II fault rates, the fault rates within 3 months after the engine is put into the market, and the fault rates within 12 months after the engine is put into the market according to the product batches. According to the fault rate report, recent fault points and long-term fault points of the engine can be deeply excavated and positioned layer by layer, and a direction is indicated for subsequent quality improvement of the engine. 本发明公开了一种发动机故障率分析报表自动生成方法，包括以下步骤：步骤1:质量指标定义；步骤2:数据抽取和标注；步骤3:故障率报表的生成，按产品批次，将不同产品批次的发动机调试故障率、发动机Ⅰ、Ⅱ类故障率、发动机投放市场后3个月内的故障率、发动机投放市场后12个月内的故障率，形成故障率报表。本发明的故障率报表可从逐层深挖定位发动机近期故障点和长期故障点，为发动机后续的质量改进指明方向。
