Production management system and non-transitory storage medium storing production management program

A production management system that manages a production line for producing a commodity, the system comprising:

• at least one production line device comprising a packaging device that packages supplied raw materials and discharges a product;
• an inspection device that constitutes the production line together with the at least one production line device and is located at a subsequent stage of the production line device;
• and
• a host computer configured to communicate with the production line device and the inspection device, and to store an arrangement of each device in the production line,
• wherein the inspection device transmits inspection result information which is information regarding an inspection result in the inspection device, to the host computer,
• wherein the host computer is configured to determine that the production line has an abnormal tendency based on the inspection result information and the processing result information,
• wherein the packaging device transmits packaging result information which is information regarding a processing result in the packaging device, to the host computer,
• wherein in a case where a number of processed products identified in the packing result information is different between the inspection device and the packaging device, the host computer determines that a production line device between the packaging device and the inspection device has an abnormal tendency and outputs an alarm,
• wherein the production line comprises a weighing device that measures a weight of the raw materials and discharges the raw materials to the packaging device after combining the raw materials to have a predetermined weight, and
• wherein in a case where a standard deviation of a weight of the product in the inspection result information is larger than a predetermined value, and the measured weight in the processing result information from the weighing device is within a predetermined range near a target weight, the host computer determines that the packaging device has an abnormal tendency and outputs the alarm.
