摘要: 在多工序锂电池制造过程中,数据分析面临多源异构和缺失挑战。针对这一问题,本文提出一种融合自回归积分滑动平均(auto regressive integrated moving average,ARIMA)模型与插值技术的填充方法。该方法通过ARIMA模型提取时间序列数据的趋势与周期性特征,结合插值技术修复因设备故障或数据采集不完整导致的缺失值,增强了对复杂数据变化规律的捕捉能力。通过多组实验表明,该方法在填充精度和数据完整性上均优于均值填充、K近邻填充和单独的插值填充方法。本文提出的ARIMA-插值混合填充模型能够有效提高锂电池制造过程的多源异构的缺失值填充质量,为后续特征提取和分析提供可靠数据基础。

Abstract: In multi-process lithium battery manufacturing, data analysis faces challenges of multi-source heterogeneity and missing data. To address these issues, this article proposes a filling method that combines autoregressive integrated moving average model (ARIMA) with interpolation techniques. The proposed method extracts trends and periodic features of time series data through ARIMA models, and integrates interpolation techniques to repair missing values caused by equipment failures or incomplete data collection, enhancing the ability to capture complex data change patterns. Multiple experiments have shown that the proposed ARIMA-interpolation method outperforms traditional techniques such as mean filling, K-nearest neighbor filling, and standalone interpolation in terms of filling accuracy and data integrity. The results confirm that the proposed method effectively improves the quality of data preprocessing in lithium battery manufacturing, providing a reliable data foundation for subsequent feature extraction and analysis.

Key words: missing value filling, data preprocessing, multi-process production, autoregressive integrated moving average (ARIMA)
