Abstract
ABSTRACT: Distributed simulation cloning technology is designed to analyze alternative scenarios of a distributed simulation concurrently within the same simulation execution session. One important goal of the technology is to optimize execution by avoiding repeated computation amongst independent scenarios. This paper introduces the design and functionalities of the modules handling the cloning of High Level Architecture (HLA) based distributed simulations. The federate cloning mechanism is established upon a decoupled federate architecture to replicate federates as described in a previous paper. This paper first presents the process of cloning at decision points and the method of coordinating and synchronizing clones, to ensure the state consistency of the overall simulation. A mapping approach is designed for the clones to map the new HLA entities created in state replication to the existing ones known to the simulation model. This entity mapping method helps in supporting user transparency and reusability of existing federate codes. An example of a simple supply-chain simulation indicates that the proposed approach provides correct distributed simulation cloning and can reduce the execution time of distributed simulations significantly. 1.
