Abstract: Provided is a production management system including: an operational data acquisition unit for 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; a quality data acquisition unit for acquiring quality data indicating quality of a target product; an analysis unit for analyzing the operational and quality data to estimate an influence, caused by an upstream product, on the quality of the target product, the upstream product being a product of an upstream production process and serving as a material in the target production process; and a feedback unit for outputting, based on an analysis result, feedback data for evaluating a production element in the upstream production process based on the quality of the target product in the upstream production process.

Abstract: Provided is a production management system including: an operational data acquisition unit for 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; a quality data acquisition unit for acquiring, as quality data indicating quality of a target product, feedback data for evaluating the production element in the target production process based on quality of a downstream product in the target production process, the feedback data being output from a production management system for managing a downstream production process of producing the downstream product by using, as a material, the target product; an analysis unit for analyzing the operational feedback data; and a control information decision unit for deciding control information for controlling the production element in the target production process based on an analysis result.

Abstract: Provided is an integrated management system including: a registration unit configured to register a plurality of production management systems for each managing a target production process as a target among a plurality of production processes of producing a product from a material in association with a sequence of the plurality of production processes; a feedback data acquisition unit configured to acquire, from at least one of the plurality of production management systems, feedback data for evaluating a production element in an upstream production process, which is an upstream process of the target production process, on a basis of quality of a target product, which is a product of the target production process, in the upstream production process; and a feedback data providing unit configured to provide the feedback data to an upstream production management system configured to manage the upstream production process on a basis of the sequence.

Abstract: Provided is a learning apparatus comprising: a correspondence receiving unit for receiving a correspondence between each produced object of a target process and a quality evaluation of each downstream produced object produced by using each produced object of the target process; a learning processing unit for generating, through learning, an estimation model for estimating the quality evaluation of the downstream produced object, by using the at least one production parameter about the production of each produced object of the target process and the quality evaluation of each downstream produced object; a calculating unit for calculating a model evaluation based on at least one of certainty or complexity of the estimation model; and a model evaluation sending unit for sending the calculated model evaluation, to an evaluation apparatus for evaluating at least one upstream process by using a model evaluation about each of the at least one upstream process.
