INDUSTRIAL EQUIPMENT OPERATION, MAINTENANCE AND OPTIMIZATION METHOD AND SYSTEM BASED ON COMPLEX NETWORK MODEL
The present invention discloses an industrial equipment operation, maintenance and optimization method and system based on a complex network model. The method includes the following steps: obtaining data of all sensors of industrial equipment, and calculating a Spearman correlation coefficient between data of every two of the sensors within the same time period; using each sensor as a node, and using the Spearman correlation coefficient as a weight of a network edge, to construct a fully connected weighted network; and obtaining, when an adjustment instruction for a target feature is received, a currently optimal parameter adjustment path of the target feature based on the fully connected weighted network. In the present invention, production equipment in reality is digitized to construct a complex network oriented to industrial big data. An optimal path for equipment parameter tuning may be found by using the network, thereby reducing dependence of an enterprise on a domain expert.

PROCESS CAPABILITY INDEX WARNING SYSTEM AND WARNING METHOD FOR THE SAME
A process capability index warning system and a warning method for the same are provided. The system includes a process capability index calculation device, which determines whether a quantity of test samples of the test device within a cycle of a warning interval is less than a quantity threshold. When the quantity of the test samples is less than the quantity threshold, the quantity of the test samples is accumulated until an end of a next cycle of the warning interval. When the quantity of the test samples is not less than the quantity threshold, the process capability index calculation device calculates and obtains process capability index values, and determines whether or not the process capability index values are less than an index threshold. When any of the process capability index values is less than the index threshold, the process capability index calculation device sends a warning message.
