In this paper a method is presented for mapping the simulation state between models of different level of detail in dynamic multiresolution modeling of discrete event material flow systems. In dynamic multiresolution modeling it is possible to inactivate a model part of certain detail and activate a model of higher or lower detail representing the same part of the system during simulation. To allow a consistent simulation, the state of the inactivated model has to be mapped to the activated model. The mapping is done by first mapping the jobs, then mapping the breakdown status and statistical variables. Experiments show that consistent states are generated, such that the simulation continues after state mapping. The errors generated by mapping are small and caused by the loss of information in the models of lower detail.
