印刷过程瑕疵风险等级数据
收藏资源简介：
风险等级与风险分数量化评估使企业能快速分配资源。高风险项触发立即停线检查；中风险项安排计划性返修；低风险项纳入常规质量监控。 通过横向对比不同设备型号的生产瑕疵等级，可作为供应商考核或设备维护优先级的依据，也可给同行业企业选择设备供应商进行参考。1.数据收集：收集生产活动中的质检数据及客户投诉工单等。对采集到的缺陷数据、客诉数据等进行整合关联清洗。 2：数据处理：根据此前经验对缺陷严重程度进行评分，严重程度高计为5分，严重程度中计为3分，严重程度低计为1分。若可返修计为1分，否为5分。客户投诉与缺陷有关联计为5分，否为1分。工艺标准偏差百分比即该项得分。风险分数=严重程度评分*0.3+返修评分*0.2+客诉关联评分*0.2+工艺标准偏差*0.3。再根据风险分数对风险等级进行分级。 风险分数≥15，则风险等级为极高；15＞风险分数≥10，则风险等级为高；5≤风险分数＜10，则风险等级为中；风险分数＜5，则风险等级为低。
Quantitative assessment of risk levels and risk scores enables enterprises to rapidly allocate production resources. Items identified as high-risk will trigger immediate line shutdown for inspection; medium-risk items will be scheduled for planned rework; low-risk items will be incorporated into routine quality monitoring. By conducting horizontal comparisons of production defect grades across different equipment models, the assessment outcomes can serve as a basis for supplier evaluation or equipment maintenance priority determination, and also provide reference for peer enterprises when selecting equipment suppliers. 1. Data Collection: Collect quality inspection data and customer complaint work orders generated during production activities. Integrate, correlate and clean the collected defect data, customer complaint data and other relevant datasets. 2. Data Processing: Score the severity of detected defects based on prior operational experience: 5 points for high severity, 3 points for medium severity, and 1 point for low severity. Assign 1 point if rework is feasible for the defect, otherwise assign 5 points. Assign 5 points if customer complaints are associated with the defect, otherwise assign 1 point. The percentage of process standard deviation serves as the score for this process parameter. The total risk score is calculated using the formula: Risk Score = Severity Score × 0.3 + Rework Score × 0.2 + Complaint Association Score × 0.2 + Process Standard Deviation × 0.3. Subsequently, classify the risk level based on the calculated total risk score: - When Risk Score ≥ 15: Risk Level is "Extremely High" - When 15 > Risk Score ≥ 10: Risk Level is "High" - When 5 ≤ Risk Score < 10: Risk Level is "Medium" - When Risk Score < 5: Risk Level is "Low"
