PROBLEM TO BE SOLVED: To make it possible to check quality in line with an actual manufacturing situation more flexibly without effort.SOLUTION: When an actual value acquisition section 105 acquires a temperature measurement value which is the actual value of a newly manufactured product, a statistic value calculation section 102 calculates the average value of a temperature measurement value measured for each manufacturing process of each product and a standard deviation by statistical processing of a plurality of actual values stored in an actual value storage section 101 to calculate the range of three times of an average value ± a standard deviation as a statistic value. Next, a detector 103 determines whether a temperature measurement value that the actual value acquisition section 105 has newly acquired is within the range of three times of an average value ± a standard deviation which is a statistic value calculated by the statistic value calculation section 102.SELECTED DRAWING: Figure 1 |
