In this thesis, based on the temporal relations of indeterminate instant, the definition and simultaneous temporal relations of indeterminate periods are proposed. Because of the characteristics of the history case data and requirement of the association rules mining, we use a DHP algorithm with additional constrains and composite items, integrating the temporal relations of indeterminate periods, to mine interesting association rules. In the end, a complete model of data mining is proposed.
