Title:
ANALYSIS DEVICE FOR EVENT THAT CAN OCCUR IN PRODUCTION FACILITY
Document Type and Number:
WIPO Patent Application WO/2021/053782
Kind Code:
A1
Abstract:
A first analysis device according to the present invention is provided to a production facility that is for production of products and that has at least one driving means for driving the production facility and at least one monitoring means for monitoring the production, the driving means and the monitoring means having one or more controllable feature amounts, the first analysis device being for an event that can occur in the production facility. The first analysis device is provided with a control unit and a storage unit, wherein the storage unit stores a plurality of the feature amounts and the control unit causes execution of: a step for calculating correlations with respect to the event between the plurality of feature amounts; a step for, when one of the correlations indicates a strong correlation satisfying a predetermined requirement, generating a group including the plurality of feature amounts such that one of the feature amounts having a strong correlation is employed and the other feature amounts are not employed; a step for constructing a causal relation model that indicates causal relations between the plurality of feature amounts included in the group; a step for constructing causal relations between all the feature amounts including the other feature amounts that are unemployed; and a step for applying causal relations pertaining to the one feature amount also to causal relations of the other feature amounts.
