Meanwhile, the convergence of manufacturing and IT is changing the paradigm of production methods and is emerging as a key factor in the resurgence of the manufacturing industry. However, as user requirements for cost reduction increase due to the massive increase in data and the worsening economy, it is necessary to search for diversified solutions.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .
