摘要
In view of the problems of small sample size and uncertain distribution in designing quality control charts for multi-variety and small-batch manufacturing processes, a multi-objective optimization design method based on non-parametric, adaptive and dynamic EWMA control charts is proposed. According to the theory of nonparametric statistics and the idea of adaptive control, control chart statistics independent of sample data distribution are constructed, and a dynamic sampling method based on clustering distance is designed to realize sample sampling; On this basis, multi-objective optimization design of the control chart is carried out considering the statistical and economic characteristics. Based on the improved artificial fish swarm algorithm and cloud clear comprehensive evaluation method, the model is solved, and the non parametric adaptive dynamic EWMA control chart for multi variety and small batch system is constructed. Finally, taking the manufacturing process of aerospace complex components as an example, the dynamic monitoring of the manufacturing process is carried out. The results show that the proposed method can quickly monitor the abnormal quality and has high monitoring performance, which proves the effectiveness and feasibility of the method, and provides an effective way for the actual quality monitoring of multi variety and small batch manufacturing process. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
