Abstract: A mounted board manufacturing system that manufactures a mounted board, which is a board mounted with a component. The mounted board manufacturing system includes: at least one component loading device that executes a component loading operation for loading the component on a board; a rule base with which at least one machine parameter for executing the component loading operation performed by the at least one component loading device can be calculated; an operation information aggregator that aggregates, for each component data, results of processing executed by the at least one component loading device, together with operation information; and a calculation processor that selects, as actual training data, component data corresponding to an operation result that exceeds a predetermined reference, from the operation information aggregator, and estimates at least one machine parameter of a new component, using the actual training data, the rule base, and basic information of the new component.

Abstract: An abnormality analysis device including: an overall information obtainer that obtains overall information indicating an overall feature amount of a manufacturing system; an overall abnormal degree calculator that calculates an overall abnormal degree that is an abnormal degree of a whole of the manufacturing system by statistically processing the overall information; an individual information obtainer that obtains individual information indicating a feature amount of each of the plurality of constituent elements; an individual abnormal degree calculator that calculates an individual abnormal degree that is an abnormal degree of each of the plurality of constituent elements by statistically processing the individual information; and a determiner that determines whether or not the overall abnormal degree exceeds a threshold value, wherein the individual abnormal degree calculator calculates the individual abnormal degree when the determiner determines that the overall abnormal degree exceeds the threshold value.

Abstract: An unauthorized communication detection device that detects unauthorized communication in a manufacturing system that manufactures products includes: an obtainer that obtains operation information of the manufacturing system; a storage that stores element information indicating one or more target elements among a plurality of elements related to manufacturing of the products; a specifier that specifies, for each of a plurality of communications performed in the manufacturing system, an element corresponding to the communication, based on the operation information; a calculator that calculates an abnormal degree of each of one or more communications, which satisfy that the element specified by the specifier is included in the one or more target elements indicated by the element information, among the plurality of communications; and a determiner that determines that, when an abnormal degree calculated by the calculator is larger than a threshold value, a communication corresponding to the abnormal degree is the unauthorized communication.
