Abstract

A hierarchical scheduling approach for non-iterative cosimulation is presented. With an increasing number of subsystems the number of possible combinations and permutations increases dramatically, resulting in an unsolvable problem to define a proper co-simulation scheduling for application engineers. This paper shows an approach to get an optimal trade-off between simulation duration and simulation accuracy by the usage of a multi-objective optimization approach to find an optimal scheduling for hierarchical co-simulation.
