摘要
为提高科研管理系统的群体交互性,改善业务流程动态性,优化资源共享率,提出了工作流技术与社交网络工具整合的体系结构,采用J2EE技术进行了系统实现。通过Petri网进行建模,以JBPM(业务流程管理)工作流引擎为技术框架,解决了业务流程的变更问题,提高了科研活动的协作效率,增强了系统的可扩展性和灵活性。针对科研协同平台下访问控制的约束条件较为复杂的问题,给出了一种增强型RBAC模型,提高了系统的可靠性及安全性。
To improve group interaction in scientific research management system, ameliorate dynamics of business processes and optimize the rate of resource sharing. A system architecture is proposed combined with workflow technologies and social networ- king tools, and the system is implemented by J2EE technology. Petri net as the modeling theory and Java business process mana- gement （JBPM） workflow engine as the technical framework, which is used to solve the problem of business process changes, improve collaboration efficiency of research activities and enhance scalability and flexibility of the system. Aiming at solving the problem of complex access control constraints in the research collaboration platform, an enhanced role-based access control （RBAC） model is proposed to improve the reliability and safety of the system.
