System state assessment of a grey immune mechanism-based organic manufacturing system

Based on a comparison of manufacturing and biological organism systems, we have proposed the concept of an organic manufacturing system. To eliminate promptly uncertain disturbances during the organic manufacturing system´s operation, an immune monitoring model of an organic manufacturing system, analogous to a biological immune system mechanism is proposed. The implementation of immune recognition, assessment, learning, memory and regulation in response to abnormal disturbance factors is investigated. The system´s grey assessment model based on an analytic hierarchy is carefully analyzed, and the effectiveness of the system state assessment method is verified experimentally through simulation.
