Abstract
This industrial system is characterized by being provided with: a storage unit that stores design data used when constructing an industrial line; a simulation execution unit that executes a simulation of movement of the industrial line, based on the design data; and a detection unit that compares a result of the simulation with the movement of the industrial line during operation and detects an abnormality in components of the industrial line. With such a configuration and movement, the present invention can be utilized for line operation support and high-resolution abnormality detection.
