The invention relates to the technical field of agent collaboration systems, in particular to a power station equipment anomaly detection decision management method based on Agent collaboration and related equipment, the system constructs four functional modules of a detection Agent, a diagnosis Agent, a knowledge Agent and a scheduling Agent, and real-time collection and standardized processing of multi-source heterogeneous detection data are achieved. The detection Agent monitors the standardized data in real time, and triggers the scheduling Agent to generate a diagnosis task tree when the standardized data is abnormal; and the scheduling Agent issues the subtasks to the diagnosis Agent for root cause analysis, or calls the knowledge Agent to obtain auxiliary diagnosis knowledge. The diagnosis Agent generates a preliminary conclusion, the knowledge Agent provides domain knowledge support, and the scheduling Agent fuses the information of the diagnosis Agent and the knowledge Agent to form a final decision containing an abnormal level, a risk level and an operation and maintenance strategy. According to the system, through data sharing and task collaboration between Agents, accurate identification, rapid diagnosis and scientific decision making of power station anomalies are realized, and the operation and maintenance efficiency and safety are improved.

A system and method for multivariate learning and optimization that repeatedly generates self-organizing experimental units (SOEUs) based on one or more hypotheses of a randomized multivariate comparison of a process decision to be provided to a user of the system. The SOEU is injected into the system to generate a quantitative inference regarding the process decision. In response to injecting the SOEU, at least one confidence interval within the quantization inference is identified, and the SOEU is iteratively modified based on the at least one confidence interval to identify at least one causal interaction of the process decision within the system. Causal interaction can be used for testing, diagnosis and optimization of system performance.
