Abstract

While there has been much attention paid to the applications of Modeling and Simulation (M&S) by the Department of Defense (DoD) lately, little has been done to address those broad technology areas that enable application-oriented simulations to be more easily constructed, run and analyzed. Model Composabilty is the ability to compose models/modules across a variety of application domains, levels of resolution and time scales. A composability framework for simulations offers a quantum leap in capability and provides the sought after ease of use. However, Composability is still a frontier subject in Modeling and Simulation, and current capability is limited. While model reuse is close to the Holy Grail of M&S, the goal is not within sight. We are discovering that unless models are designed to work together, they don't (at least not easily and cost effectively). Without a robust, theoretically grounded framework for design, we are consigned to repeat this problem for the foreseeable future. This position paper outlines the challenges and basic researches that are needed for composable simulation developments.
