Estimation of uncertainty for logic output produced by multi-dimensional data hypercubes

This paper investigates the problem of uncertainty estimation for logical output produced by multidimensional hypercube structures under the conditions of real disturbances of data in information databases and multidimensional data warehouses. The meaning of measure of data uncertainty is introduced. The criteria of decrease (increase) of uncertainty measures for logic output have been received taking into account the different changes of hypercube basic parameters.
