The AsiaSim conference is an annual international conference that started in 1999, and has primarily been organized by the three Asian simulation societies, Chinese Association for System Simulation (CASS), Japanese Society for Simulation Technology (JSST), and Korea Society for Simulation (KSS). In 2011, the Federation of Asia Simulation Societies (ASIASIM) was set up to promote the advancement of modelling and simulation in industry, research and development in Asia and beyond. International Conference on Simulation Technology (JSST 2014), which is annually organized by Japan Society for Simulation Technology (JSST), will be held to disseminate progress in the state-of-the-art of simulation methods and report their applications in natural and social sciences. This event is to bring together outstanding researchers in modeling, simulation and scientific computing areas to share their expertise and experience.
