RESULT CACHING FOR IMPROVING STATISTICAL EFFICIENCY OF COMPOSITE SIMULATION MODELS

Embodiments of the present invention provide a method for result caching to improve the statistical efficiency of a composite model comprising a first component model and at least one other component model. The method comprises developing at least one metamodel for at least one component model of the composite model, computing a re-use factor that maximizes an asymptotic efficiency measure based on the metamodel, determining a number of executions to run for the composite model, and determining a number of executions to run for the first component model based on the re-use factor and the number of executions to run for the composite model. The number of executions to run for the first component model is fewer than the number of executions to run for the composite model. Each output generated from each execution of the first component model is cached and provided as input to another component model.
