The Analysis, Based On Standardized Principle Hla Specification

With the development of simulation technology at very fast speed, especially with its tremendous development in the field of military affairs and national defence, there bring up hearty requirement to the standard and criterion of simulation. In the field of ours national defence, the build of simulation system come down to a series of arms of services, weapon equipment and many departments, the simulation systems are often great and complex, but they have many common proportions, thus bring one question, namely the question of standardization. Occasionally, the exploitation of two different systems did not follow unitive standard and criterion, they can't join and use together, so can not form effective battle effectiveness. We must hurry up to strike up unitive standard and criterion in horse and foot, otherwise, the more based systems, the more waste and confusion. It is obvious that it is a quite urgently requirement to ensure simulation interoperability and reuse of these systems, the radically approach is the standardization of simulation. With the development of simulation technology, now have come into the phase of high level architecture, and have become an emphasis of the currently development of simulation technology. So that we spread the study of HLA standard and criterion. The analysis of HLA criterion based on standardization theory have an extraordinary important meaning to expedite the extension and application of HLA and the foundation of great military affairs simulation systems.At first, the article simple analyse some basic work elements and basic method of standardization activity, analyse and discuss some questions of term form, definition and term manage work. Then, in allusion to the development process of HLA standard from initial edition to presently up to date IEEE 1516 standard, analyse in what aspects the changes have taken place and how these changes make HLA better satisfy simulation requests.Finally, particular analyse some difficulties in the apprehend of simulation interoperability and the two methods to define simulation interoperability, analyse how it sustain interoperability in HLA from the apprehend of interoperability of HLA , the elements and methods of standardization activity of HLA, term definition and term manage work of HLA and the three HLA's composings: HLA Rules, HLA Federate Interface Specification and HLA Object Model Template.
