基于相对决策条件的规则提取方法

提出一种多重查询调度算法——连续读取特性(CRP)调度算法，该算法应用连续读取特性，使查询的数据可以重组出某些连续关系，从而使之具有连续读取特性，解决了现有算法中有部分系统资源闲置的问题，提高查询速度。仿真实验结果表明，CRP调度算法的系统利用率和系统性能均优于其他算法。

Rule Extracting Method Based on Relative Decision Condition

The concept of relative decision is put forward and the method for finding absolute reduction decision rule through combining rules of relative decisional condition sets is given in this paper. In the process of decision table reduction, the discernibility matrix between decision category should be created in order to decide the relative decision conditions which are conjoined to find the decision conditions of all the decision classes. The relative decision conditions are extracted by creating smaller discernibility matrix, and the scales of computing can be cut down substantially and saving storage space.
