PROBLEM TO BE SOLVED: To provide an operation state evaluation device that generates an operation evaluation function with an operation factor having a large effect on the quality of an operation state being input variable data and evaluates the operation state of a process.;SOLUTION: An operation state evaluation device includes: a correlation analysis unit that performs probability distribution correlation analysis for classifying operation conditions included in result data indicating an operation state of a process into plural ranges by operation variable and calculating the probability distribution of quality determination results that are evaluation of quality of the operation state for each classification on the basis of evaluated result data including the result data and the quality determination result and for extracting an operation variable having a high correlation with the quality of the operation state of the process on the basis of the degree of effect on operation calculated from each probability distribution; an operation evaluation function configuration unit that configures an operation evaluation function using a support vector machine on the basis of the operation variable having a high correlation and the quality determination results; an operation evaluation unit that calculates an operation evaluation value for new result data on the basis of the operation evaluation function; and an operation evaluation output unit that presents the operation evaluation value for the new result data.;COPYRIGHT: (C)2013,JPO&INPIT
