PROBLEM TO BE SOLVED: To provide a situation analytical system capable of analyzing easily and quickly a situation of a monitoring object by using a Mahalanobis-Taguchi method, and capable of correcting properly an error in analysis.;SOLUTION: An indication receiving part 101 receives an indication about the propriety of accumulation as to data obtained from the monitoring object. A data accumulation means 102 accumulates the data according to the indication received by the indication receiving part 101. A reference space preparing means 103 prepares a reference space based on the data accumulated in the data accumulation means 102. A data acquiring means 104 acquires the data from the monitoring object. A distance calculating means 105 calculates a Mahalanobis distance by inputting the data obtained by the data acquiring means 104 into the reference space prepared by the reference space preparing means 103.;COPYRIGHT: (C)2007,JPO&INPIT
