Abstract

This study proposed a new real-time manufacturing process monitoring method to monitor and detect process shifts in manufacturing operations. Since real-time production process monitoring is critical in today’s smart manufacturing. The more robust the monitoring model, the more reliable a process is to be under control. In the past, many researchers have developed real-time monitoring methods to detect process shifts early. However, these methods have limitations in detecting process shifts as quickly as possible and handling various data volumes and varieties. In this paper, a robust monitoring model combining Gated Recurrent Unit (GRU) and Random Forest (RF) with Real-Time Contrast (RTC) called GRU-RF-RTC was proposed to detect process shifts rapidly. The effectiveness of the proposed GRU-RF-RTC model is first evaluated using multivariate normal and non-normal distribution datasets. Then, to prove the applicability of the proposed model in a real manufacturing setting, the model was evaluated using real-world normal and non-normal problems. The results demonstrate that the proposed GRU-RF-RTC outperforms other methods in detecting process shifts quickly with the lowest average out-of-control run length (ARL) in all synthesis and real-world problems under normal and non-normal cases. The experiment results on real-world problems highlight the significance of the proposed GRU-RF-RTC model in modern manufacturing process monitoring applications. The result reveals that the proposed method improves the shift detection capability by 42.14% in normal and 43.64% in gamma distribution problems.
