Abstract
In this paper, we present an improvement to evaluate the HLA lookahead for distributed DEVS/G-DEVS models in a HLA-compliant environment. The models considered in this distributed simulation have state lifetimes functions of several state variables. We use the graph theory Dijkstra search to compute the different values of the state variables and a mathematical function analysis to determine the lookahead for the model states. We illustrate on an example how this solution extends the range of DEVS/G-DEVS models that can be involved into distributed simulations.
