Description
Summary:The complexity of multi-variety mixed production mode makes it difficult to find out the critical points to guide the quality control and improvement activities of the shopfloor. To excavate these critical nodes, a complex network analyze method is proposed in this article. A quality control network of multi-variety mixed production is constructed based on directed weighted network using unqualified batches’ manufacturing information. In order to evaluate the critical degree of a manufacturing resource node of quality control network, this article proposes a QCD-NodeRank indicator and an evaluation method based on improvement of PageRank method. This critical degree evaluation method reflects the connection relationship of manufacturing resource nodes and considers the quality situation of them. The manufacturing resource node with high QCD-NodeRank values is considered to be the critical one. Then, a hierarchical clustering method is introduced to evaluate the critical nodes for quality control. Finally, an example is provided to illustrate the proposed approach.
