A data analysis system includes: a memory; and a processor connected to the memory and that acquires data to be analyzed. The data to be analyzed includes parameters relating to a production element of a product produced in each of production batches; and an indicator for evaluating the product. The processor outputs, to the memory, the acquired data to be analyzed. The memory stores, in each of the production batches, the parameters and the indicator associated with the parameters. The processor calculates a correlation feature value for each of the production batches based on a correlation between the parameters and data of the correlation and the parameters. The processor causes a display to display the calculated feature value.

A method to be performed in a production support system configured to process a raw material and to produce a product. And the method includes: acquiring a plurality of element values relating to production elements of the product; determining whether the element values are within allowable ranges in which a quality of the product meets a predetermined allowed quality; resetting the allowable ranges of one or a plurality of other element values to the allowable ranges in which the quality of the product meets the predetermined allowed quality, upon determining that at least one element value exceeds the allowable range; and outputting information about the reset allowable ranges.

Production support system, method and product for monitoring production quality using adjustable allowable ranges

An information management apparatus may include a first collection unit that collects a measurement value measured by a measurement device connected to the information management apparatus via a network, a second collection unit that collects status information indicating statuses of the measurement device and the network, and a correction unit that correcting quality information indicating validity of the measurement value, which has been collected by the first collection unit, by using the status information that has been collected by the second collection unit.
