摘　　要：以某重机企业工具工装管理系统的需求为背景,提出了基于角色、身份和用户的多维访问控制模型,解决了分布式多层协同工作环境下的访问控制问题;利用计算机全球唯一标识符和数据库技术解决了协同工作的并发控制问题;采用分层设计降低了系统的复杂程度,采用面向对象程序设计和可视化编程技术,使复杂的计算机语言编写量降到最低限度,开发出的工具工装管理系统可大幅度提高重机企业工具工装管理水平。In view of the requirements of the tool and jig management system in a certain heavy machinery enterprise, the multi-dimensional access control model was proposed based on role, identity and user to solve the access control in distributed multi-layer cooperative working environment. The globally unique identifier and database technology were used to solve the concurrency control during collaborative working process. The hierarchical design was used to reduce the complexity of the system, the object-oriented program design and visual programming technique were used to make the duty of compiling computer language to the minimum. The tool and jig system could greatly improve the tool and jig management level in heavy machinery enterprises.
