Quality Control Model for Complex Manufacturing System Based on Danger Theory of Biological Immune System

In this article we introduce a new quality control model for complex manufacturing system which has the potential to enable enterprise to protect itself from harmful non-conformance in a way like biological system. The model is based on danger theory. In the proposed quality control model, a co-stimulation is necessary to confirm the danger implied by the presence of a detected quality variation, anomalies that are not confirmed by signal 2, or harm were not considered as faults. With the multiple confirmation mechanism and dynamic detector update, the range of quality defects space is reduced. High levels of quality defects detection is made possible at reasonable computational cost. The architectures and behavior of the proposed quality model resembles the structure and behavior of biological immune system, which may improve the reliability and efficiency of the manufacturing system, especially for the highly dynamic complex manufacturing system.
