Research and implementation of research collaboration platform based on workflow

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 networking tools,and the system is implemented by J2EE technology.Petri net as the modeling theory and Java business process management(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.
