Claim:
1. A processor based method of detecting, in real time, incorrect operation of an engineering asset of which measurement values of operating parameters are taken over time, the method comprising, sequentially, a first part of recording events, a second part of recalling events, and a third part of performing a back check, wherein: each of said first and second parts comprises the steps of: receiving a vector A of n measurement values, where A converting each of the measurement values A concatenating, superimposing or adding all of the vectors B one of said first and second parts comprises the additional step of transforming each of the vectors B said first part comprises the further steps of: creating a binary vector M that has P bits set; recording a date vector against vector M in a database Z; and associating vector D into a correlation matrix memory R against vector M; said second part further comprises the steps of: using vector D to access the correlation matrix memory R to recall an association vector S; and applying vector S to the database Z to recover a date associated with vector S; and said third part comprises the steps of: checking similarity between a recall vector A′ and a previously recorded vector A; generating an alert signal that indicates incorrect operation of the engineering asset in real time when a measurement value of recall vector A′ differs from the corresponding measurement value of previously recorded vector A by an amount greater than a predetermined threshold value; and outputting data to indicate at least one of: one or more previously recorded vector A that is closest to the recall vector A′; the binning configurations of the recall vector A′ and one or more previously recorded vector A that is closest to the recall vector A′; and each measurement value that was found to differ between the recall vector A′ and a previously recorded vector A.
