The roles and system resources are connected directly in normal role-based access control (RBAC) model, but the RBAC model can not be used widely in large information systems which have lots of system resources, because of the poor maintainability. This paper proposes an access control model based on role and function body (FRBAC) which adds function bodies between roles and permissions. The paper...
The report designer is the core part of flexible report systems which provides the decision support to information systems. In this paper, we propose an ontology-based report designer which provides a flexible mechanism to generate different reports. The paper gives the principle of report designer and details the formal description of report designer ontology. At last we give an application instance...
This paper proposes a flexible workflow management system (WfMS) model based on ontology through analyzing the architecture and generic knowledge of workflow management systems. The paper specially gives the composition principle of flexible workflow management system and proposes the formal description of workflow ontology. At last this paper gives the composition algorithm and an example which uses...
Through analyzing the architecture and domain commonness of enterprise information system (EIS), the paper proposes a composition model of EIS based on domain ontology. The paper specially gives the formal description of EIS domain ontology, and proposes the composition algorithm based on semantic similarity of concepts in domain ontology. At last this paper gives an example which uses the composition...
The discrete particle swarm optimization (DTSO) has many merits, for example simple, rapid convergence speed. This paper proposes an approach for web services composition based on quality of service (QoS) and DTSO. In the case of lots of web services, this approach has an obvious effect. The simulation results comparing with genetic algorithms (GAs) show that it can produce better results.
