Abstract

A software system (2) utilizing a filtered priority queue (10) is provided. A filtering module (4) is operable to access a plurality of data records of entities (16, 18, 20, 22, 24, 26 and 28) of a priority queue and to filter and arrange the data records in a memory storage device (8) to form the filtered priority queue (10). The filtered priority queue (10) comprises a remaining set (12) and a filtered set (14). The filtered set (14) contains a first subset of data records (20, 22, 24, 26, and 28). The first subset of data records (20, 22, 24, 26, and 28) form sublevels of a lattice. The remaining set (12) contains a second subset of data records (16 and 18). The second subset of data records (16 and 18) comprise lattice heads of the lattice. A sorting module (6) is coupled to the filtering module (4). The sorting module (6) is operable to access the remaining set (12) and to order the data records (16 and 18) in the second subset of data records to identify a data record (16) of a most critical entity.
