| 摘 要： | 采用组合优化方法研究了考试系统中题库量与随机抽取试题量的关系，给出了在约束条件下题库量与试题量之间的数据模型和无约束条件的计算式。实验表明，只要题库量达到3 000或3 000以上时，用计算机从题库中随机抽取100个试题生成一份试卷，其重复率很低，可满足常见的考试要求。

| Abstract: | This paper studied apply combinatorial optimization methods to the examination system and the relation between test questions-base numbers and random extraction deeply, presented the mathematical model and calculating formulas in unconstraint and constraint conditions respectively. The experiment results show that when test questions-base numbers reach 3 000, it can satisfy the requirement of traditional examination by random extraction 100 questions using computer. |
