PROCESS ABNORMAL STATE DIAGNOSING DEVICE AND ABNORMAL STATE DIAGNOSING METHOD

摘要

An anomalous state diagnostic device 1A diagnoses an anomalous state of a process based on a plurality of deviation indexes for the magnitude of deviation from a reference that is the normal state of the process, and includes: a color mapping unit 64 configured to configure a two-dimensional matrix that has a first axis as an axis of a temporal factor including time and that has a second axis as an axis of an item of each deviation index, associate each cell of the matrix with data for an item of the deviation index and a temporal factor, and allocate a color in accordance with the magnitude of the deviation index to each cell of the matrix; and a color map display unit 65 configured to display a color map produced by the color mapping unit.
