Production information management system and production information management method

A production information management method using a production information management system, wherein

• the production information management system includes
• a storage device that stores
• 4M (man, machine, material, and method) data information including time series data in which a state of each element of 4M per unit time is associated with acquisition accuracy of 4M data defined for each target and acquisition method of 4M, and
• analysis model information defining a criterion for determining a production loss from a combination of the 4M data information,
• a processor, and a display unit, and
• the processor performs
• analyzing the 4M data information by the analysis model information to estimate a production loss, and calculating estimation accuracy for the each production loss to generate production loss information, and
• production loss displaying of causing the display unit to display the production loss information.
