This proposed work is Decision Diagrams are a data structure that allows compact representation of discrete functions Boolean functions. The construction of DDS in terms of memory and time is considered as problems .we proposed method of eliminating, merging and reordering the set of cubes in matrix specification that results in the reduction of both memories occupied and time complexities of the construction of DDs. First we employ elimination algorithm followed by merging and then again elimination algorithm and reordering the set of cubes .In this way, the number of operations on the nodes is reduced. This reduction results in a decrease both in the number of temporary nodes and construction time the experiments show that the total number of created nodes is reduced on an average by 35% and construction time is decreased by 49%.
