摘要: 提出了一个功能可重构的MES系统访问控制机制的解决方案。对离散制造企业组织机构进行分析,给出了组织相关概念的基于BNF的形式化定义,建立了组织职责分配模型。对RBAC访问控制模型进行扩展,建立了Group-RBAC模型,给出了基于关系运算的权限配置理论模型。基于Group-RBAC给出了航空发动机装配车间MES功能可重构设计方案。

Abstract: A solution of access control mechanism of reconfigurable Manufacturing Execution System(MES) is proposed.Analyzing the organization in the discrete manufacturing enterprise,some definitions about organization are formally expressed in BNF and a model of responsibility assignation of organization is given.In the basis of organization model,a Group-RBAC model extending from RBAC model is constructed.The method of permission granting is expressed in database relation operation.The Group-RBAC model is utilized to construct a reconfigurable MES for the aero engine assembly workshop.

Key words: access control, reconfigurable, discrete workshop, Manufacturing Execution System(MES), Role-Based Access Controls(RBAC)
