MES系统对精车内圈生产计划控制分析数据

轴承制造行业中，精车内圈生产领域是对高精尖技术要求及其苛刻的领域，下游应用领域包括汽车制造、工程机械、高端农机、摩托车、家电、减速机等行业。在行业领域内引进MES系统，目的是通过在生产过程中的各种数据要素感知、采集和转化，实现需求和生产的精准对接，减少因信息不对称产生的产能浪费，最大化提升产能效率。而企业引进MES系统后，是否真正实现了该行业领域产能效率的提升，是该行业内众多企业共同的疑问，这需要通过对相应数据要素的分析计算去体现。本条数据分析解决的即是通过算法规则运算分析MES系统是否真正实现了该行业领域产能效率的提升的问题。提取的数据要素有：上报完工数(CRD)、实际生产时长(PD)、计划日产量(RPO)。1.算法规则：根据公式计算综合生产效率(CPE)= CRD/（RPO*PD）*100%。实际生产时长按天数计算，不足1天的按1天计算。2.数据分析：若CPE>100%,则状态为“生产超标”；若CPE=100%,则状态为“生产达标”；若CPE<100%，则根据上报完工数或实际生产时长，标记状态为“生产不达标”。3.根据状态分析结论：若状态为“生产超标”，则代表引进MES系统成功实现了产能效率提升；若状态为“生产达标”，则代表引进MES系统既没有提升产能效率、也没有降低产能效率；若状态为“生产不达标”，则代表引进MES系统反而降低了产能效率。

In the bearing manufacturing industry, the precision turning inner ring production sector imposes extremely stringent requirements on cutting-edge technologies. Its downstream application fields include automotive manufacturing, construction machinery, high-end agricultural machinery, motorcycles, home appliances, reducers and other industries. In this industry, introducing the Manufacturing Execution System (MES) aims to achieve precise docking between market demand and production through the perception, collection and transformation of various data elements in the production process, reduce production capacity waste caused by information asymmetry, and maximize production efficiency. However, whether the introduction of MES has truly improved the production capacity efficiency of this sector has become a common concern for numerous enterprises in the industry, which needs to be verified through analysis and calculation of corresponding data elements. This data analysis aims to solve the problem of verifying whether the MES has truly improved the production capacity efficiency of this sector via algorithmic rule-based operations. The extracted data elements are: Reported Completed Quantity (CRD), Actual Production Duration (PD), and Planned Daily Output (RPO). 1. Algorithmic Rules: Calculate the Comprehensive Production Efficiency (CPE) using the formula: CPE = (CRD / (RPO * PD)) * 100%. Actual production duration is calculated in days, with any duration less than 1 day counted as 1 day. 2. Data Analysis: If CPE > 100%, the status is marked as "Overproduction"; if CPE = 100%, the status is marked as "Standard Production"; if CPE < 100%, the status is marked as "Underproduction" based on the reported completed quantity or actual production duration. 3. Status-based Analysis Conclusion: If the status is "Overproduction", it indicates that the introduction of MES has successfully improved production capacity efficiency; if the status is "Standard Production", it means that MES has neither improved nor reduced production capacity efficiency; if the status is "Underproduction", it indicates that the introduction of MES has instead reduced production capacity efficiency.
