A simulation-model information management system is introduced. First, after arguing about the importance about model management, the definition of simulation-model lifecycle information management is presented. Secondly, the main research contents about simulation-model lifecycle information management are described. As is presented, in the simulation-model information management system, model management can be divided into two phases by time, management phases of developing model and of running model. At last, the framework and main functions of model information management system are discussed.
