Abstract:

The complex multistage manufacturing process contains many quality characteristics which are characterized by high dimensional multicollinearity and group effect. In the actual production process, subjected to the cost and technology constraints, all quality characteristics cannot be monitored. How to identify the key variables from a lot of quality characteristics with high dimensional multicollinearity and group effect has become increasingly necessary. To solve this problem, The Partial Least Squares- Adaptive Elastic Net (PLS-Aenet) method is applied to model and analyze the complex multistage manufacturing process and identify the key quality characteristics of the process. The PLS-Aenet method is used and the state space idea is integrated to model and identify the key quality characteristics of complex multistage manufacturing processes, and the specific steps are given to identify the key quality characteristics based on the PLS-Aenet Net method. Finally, the applicability and effectiveness of the PLS-Aenet Net method and the variable selection method such as Ridge Regression、Lasso、PLS-Lasso、Elastic Net method in the identification of key quality characteristics of the complex multistage manufacturing process are compared through simulation analysis. The simulation and real case results show that the PLS-Aenet method achieves a more effective performance when the key quality characteristics are strongly correlated with each other.

Key words: multistage manufacturing process, complex product, state space model, PLS-Aenet, key quality characteristics
