英文摘要：

Based on the indetermination of the optimized distribution problem about many factor resources, this text built the assigned model of many indetermination factors based on the number zone, showed the theories of the model＇s establishment, gave a whole optimized arithmetic, expanded the assigned model of many indetermination factors based on the num ber zone, solved the optimized distribution problem about many factor resources under the indetermination condition. Thinking about the effect of many factors, based on the efficiency of the mission accomplishment, taking example for the distribution problem about many targets and many factors with five types of resources, it obtained the whole optimized results about the assigned model. This text developed the decision approach for the research of the optimized distribution problem about the resources under the indetermination condition.
