DEVS-HLA: 이 기종 분산 시물레이션 틀

Abstract

We describe a heterogeneous simulation framework, so called DEVS-HLA， in which

conventional simulation models and the DEVS (Discrete Event System Specification)

models are interoperable. DEVS-HLA conceptually consists of three layers: model layer,

DEVS BUS layer, and HLA (High Level Architecture) layer. The model layer has a

collection of heterogeneous simulation models, such as DEVS, CSIM, SLAM, and so on, to

represent various aspects of a complex system. The DEVS BUS layer provides a virtual

software bus, DEVS BUS, so that such simulation models can communicate with each

other. Finally, the HLA layer is employed as a communication infrastructure, which

supports several good features for distributed simulation. The DEVS BUS has been

implemented on the HLA!RTI (Run-Time Infrastructure) and a simple example of a

flexible manufactu꾀ng system has been developed to validate the DEVS-HLA.
