Collaborative software infrastructure for adaptive multiple model simulation

This paper presents a software infrastructure being developed to support the implementation of adaptive multiple model simulations. The paper first describes an abstraction of single and multiple model simulations into the individual operational components with a focus on the relationships and transformations that relate them. Building on that abstraction, consideration is then given to how adaptively controlled multiple model simulations can be constructed using existing simulation components interacting through functional interfaces. This includes addressing how experts would provide the infrastructure with the needed components and define the relations and transformations needed to interact with other components, and for users to define the simulations they wish to be executed. Next, a discussion of the software environment used to implement the multiple model simulation infrastructure is given. Finally, there is discussion of the implementation, using this infrastructure, of two multiscale and one multiple fidelity model simulation applications.
