This paper proposes the strategies of intelligent fixing test paper based on granularity synthesis by forming different granularity spaces of items bank,considering respectively the restrictions about the test paper according to priority.

• 提出了基于粒度合成计算原理的组卷策略；该策略通过形成题库的不同粒度空间；将试卷的多指标约束按优先权进行分级考虑；最后根据粒度合成算法实现智能组卷.
