Abstract:
A system for analyzing manufacturing process data to identify manufacturing process components affecting characteristics of a product produced by a manufacturing process, the system comprising:a plurality of data stores holding a plurality of records containing process data, each record associated with at least one of the process components;a virtual database engine coupled to the plurality of data stores;a user interface enabling a user to select records from within the data stores;a proxy virtual database created by the virtual database engine, the proxy database comprising copies of the selected records;a statistical analysis engine operatively coupled to the proxy virtual database to apply statistical analysis operations to the selected records within the proxy database and identify process components or combinations of process components having a significant effect on the characteristics of the product produced;a first graphical interface component displaying a two-dimensional relationship between process components or groups of process components and characteristics of the product produced indicating directionality and extent of correlation between the identified process components and the characteristics of the product produced; anda second graphical interface component enabling display of at least three dimensional relationships indicating directionality and extent of correlation between the identified process components and the characteristics of the product produced.
