摘　　要：研究基于局部粗糙集模型下的决策规则提取.对经典粗糙集的决策规则提取进行改进,给出局部粗糙集模型下的决策规则公式,并研究相关性质.结合局部粗糙集模型给出的规则提取公式,引入参数值α,α∈(0,1),使规则提取公式的泛化能力更强,适用性更广.通过3个实例对局部粗糙集模型决策规则提取的运用进行说明.We mainly study the decision rule extraction based on local rough set model.Make improvement on the rule extraction based on classical rough set,we give the decision rule formula based on the local rough set model,and find its related theorems.Parameter valueα,α∈(0,1)is introduced into the rule extraction formula based on local rough,which makes the generalization ability and applicability of the rule extraction formula stronger.Three examples are given to illustrate the application of decision rule extraction in local rough set model.
