The Society for Modeling and Simulation International (SCS) is pleased to announce that as of January 2002, all the research articles previously published in both SIMULATION and TRANSACTIONS will be combined into a single, archival, peer reviewed monthly journal called SIMULATION: Transactions of The Society for Modeling and Simulation International. Published on behalf of the SCS, the leading society devoted to advancing the discipline and profession of modeling and simulation SIMULATION: Transactions of The Society for Modeling and Simulation International will include articles devoted to theory and applications, all with clear relevance to general modeling and simulation issues. In addition to building the knowledge base in theory, methodology and technology, the journal also aims to help professionals and researchers (particularly those involved in multidisciplinary projects) apply advances in modeling and simulation to their application areas.
