| 摘 要： | 利用含序粗集方法, 依据标准的优先序信息及标准间的支配关系, 解决了推导含序信息规则问题. 提出一种新的规则生成算法, 并与其他规则产生算法进行了简单对比. 算法按照后件由强到弱产生规则, 能保证生成极小规则, 在某种意义下规则集是完备和无冗余的.

| Abstract: | Based on preference order information carried by criteria and dominance relation between them,(deduction) of ordered information rules was solved.New rule generation algorithm GRs was proposed and a(simple) comparison with other algorithms was carried out.The rules are generated from strong to weak according to strength of rules' consequent.The algorithm ensures the minimality of rules.In some degree,the rule set is complete and non-redundant.Corresponding definition and notation,data analysis method,rule types on(Containing) Order Rough Set Methodology(CORS) are introduced also. |

| Keywords: | criteria dominance relation containing order rough set methodology rules generation algorithm completeness |
