1. A method for monitoring the status of a production order in a factory, the method comprising:
generating a production IoT model based on a production scheduling system document, the production IoT model comprising a first set of process attributes of product processing;
generating a product IoT model based on a product design specification document, the product IoT model comprising the first set of process attributes of product processing;
associating the production IoT model with the product IoT model;
learning data of a production device acquired by a data acquisition automation control system in the factory to obtain a data model representing processing steps of a product; and
matching the processing steps against the process attributes of the product IoT model and determining the status of the production order in the factory based on the matching result.
