Abstract
When credit inquiry of the enterprise is evaluated, the qualitative scoring seat might be used. At that time, it was a problem to give the standard assumed to be able to evaluate credit inquiry correctly again that objectivity was given to a qualitative evaluation. Moreover, it can be said that it is preferable to do the scoring seat to there are a lot of evaluation items an integrated evaluation by a quantitative standard. The array of the score was caught here as a kind of pattern, and the Mahalanobis distance of the quality engineering was used for the method of requesting the value of an integrated pattern from the score. Moreover, to make the rule of the pattern visible, the application of the orthogonal array was applied. As a result, it was achieved to clarify a potential structure in the factor effect chart that was requested by the numerical value that the qualitative score of 36 items unified and obtained from the orthogonal array.
