Abstract: This paper makes a research on time management services of High Level Architecture(HLA). It proves optimistic time advance can solve lack of agility and a long emluator time of conservative time advance via analyzing and comparing of conservative time advance and optimistic time advance; And it introduces a generalized list storage structure. Its two-dimensional storage effectively resolves key storage and retraction technique of optimistic time advance. By testing and verification of the arithmetic, it proves that the arithmetic shortens the emluator time and heightens real-time of the simulation system.

Key words: High Level Architecture(HLA), conservative time advance, optimistic time advance, generalized list, retract
