Air and Space Command Control Centre is extremely important in Air and space information obtaining task assignment and resource assign. First, building the conceptual model from the function, work process, control center and correlation entity information alternation relation. Second, through analyzing the model system structure and simulation flow, the task instruction list, the information obtaining task assignment model and land station detecting and control support judgment model was designed. Finally, through example the model was proved to be veracity, effectiveness, continuity and integrality.
