Production management system, production management method, and production management program

A production management method comprising:

• acquiring operational data regarding a production element in a target production process as a target among a plurality of production processes for producing a product from a material;
• acquiring quality data indicating quality of a target product which is a product of the target production process;
• analyzing the operational data and the quality data to estimate an influence, which is caused by an upstream product, on the quality of the target product, the upstream product being a product of an upstream production process which is an upstream process of the target production process and serving as a material in the target production process;
• and
• outputting, on a basis of an analysis result, feedback data for evaluating a production element in the upstream production process on a basis of the quality of the target product in the upstream production process.

A non-transitory computer readable medium having recorded thereon a production management program that, when executed by a computer, causes the computer to function as:

• an operational data acquisition unit configured to acquire operational data regarding a production element in a target production process as a target among a plurality of production processes for producing a product from a material;
• a quality data acquisition unit configured to acquire quality data indicating quality of a target product which is a product of the target production process;
• an analysis unit configured to analyze the operational data and the quality data to estimate an influence, which is caused by an upstream product, on the quality of the target product, the upstream product being a product of an upstream production process which is an upstream process of the target production process and serving as a material in the target production process;
• and
• a feedback unit configured to output, on a basis of an analysis result, feedback data for evaluating a production element in the upstream production process on a basis of the quality of the target product in the upstream production process.
