Fractal-agent based Web access control of enterprise cooperative manufacturing system

The cooperation mode based on fractal-agent of the networked cooperative manufacturing system is introduced. According to the task executing principle of the fractal-agent, the dynamic task is bound to the corresponding dynamic role. It leads to raise the fractal-agent based Web access control approach, security policy and the relating access control matrix. Furthermore, the approach is carried out to enable the secure access, administration and control of the cooperative manufacturing system. The experimental results show that the research can meet the requirement of the Web access security of the enterprise cooperative manufacturing system.

Research on DOL system based fractal control engine of the workflow management system for re-configurable manufacturing cooperation

To facilitate the re-configuration of the networked manufacturing cooperation, the theory of networked fractal cooperation is raised. The kernel of the theory contains both parts including fractal-agent and DOL based control engine of the workflow management system. The framed fractal-agent is explicated to express the cooperation organization with several levels. According to the self-similar cooperating course, a novel fractal approach is raised to simplify and to construct the control engine for re-configurable manufacturing cooperation. The control engine can be depicted by the proposed DOL formula. The complete process of the manufacturing cooperation can be implemented under the control of the expanding DOL formula. The primary experiment showed the DOL based control engine could efficiently support the workflow management of the re-configurable manufacturing cooperation and made it easy to develop and to administrate the information platform.
