Interoperating COTS Simulation Modelling Packages: A Call for the Standardisation of Entity Representation in the High Level Architecture Object Model Template

摘要

The High Level Architecture is the defacto standard for distributed simulation. Although widely used in defence-related real-time, virtual distributed simulations, the High Level Architecture has yet to make a significant impact in other simulation application areas that use COTS simulation modelling packages. There are many possible reasons for this. In an attempt to make progress in the development of distributed COTS simulation modelling applications, this paper discusses the use of the OMT in this area. This paper argues that the entity is the basis of information exchange between distributed models and that there is a the need for the standardisation of entity representation in the HLA Object Model Template. The paper attempts to do this by presenting a simple distributed simulation and demonstrates how entities can be represented in the Object Model Template as attributes and as interactions. The paper concludes that while neither representation is ideal, both can be used to represent entities and that standardisation is urgently needed.
