[Abstract]:With the development of the social economy, the market competition is increasing and more and more show the characteristics of globalization, dynamic and user driven. In the new situation, the operating environment of the manufacturing system is full of uncertainty, often accompanied by continuous and unpredictable tasks and events. How to respond quickly and effectively to the manufacturing environment All kinds of uncertain factors are the key problems that must be considered in the modern manufacturing system. In addition, it is also a difficult problem to seek the adjustment mode and scheduling technology of the manufacturing system with self-adaptive and self-organizing features. In this context, this paper, inspired by the mechanism of immuno endocrine regulation, proposes a biologically based system. The system regulation model is made and the scheduling technology of the biologically based manufacturing system is deeply discussed. The main research work is as follows: 1, the regulation model of the biological manufacturing system is established. First, the biological background of the biologically based manufacturing system is introduced. Then, the modern manufacturing system is analogized to the human body system, and the mechanism is designed. The structure and function of the unit are constructed, and the structure of the biologically based manufacturing system is constructed, and the role of different organic manufacturing units in the framework is analyzed. Finally, according to the principle of the neuroendocrine immune coordination, three regulating models of the biological manufacturing system,.2, are established, and the workshop dynamics based on the neuroendocrine regulation mechanism are studied. First, based on the analysis of the mechanism of neuroendocrine regulation, the dynamic scheduling model of the plant like manufacturing system is established. Secondly, based on the multiple feedback regulation model of neuroendocrine, the resource allocation mechanism of the biologically based manufacturing system is constructed, and the cost, delivery time and resource utilization ratio are considered in the distribution process. Then, the dynamic scheduling coordination process is analyzed for dynamic events. Finally, the experimental case is verified. The results show that the dynamic scheduling method of the biologic manufacturing system can improve the performance.3 of the manufacturing system in the dynamic environment, and study the AGV and machine based on the endocrine hormone regulation mechanism. On the basis of the analysis of the mechanism of hormone reaction diffusion in the endocrine system, the method of simultaneous scheduling of AGV and machine tools is proposed. Secondly, based on the antagonism and synergistic law of hormone, the secretory mechanism of AGV and machine tools is established. Then, the collaborative process of simultaneous scheduling between AGV and machine tools is analyzed for transportation tasks. Finally, the results show that the proposed method is more superior in solving the scheduling problem by comparing with other methods in the literature, and the results are.4 based on the neuroendocrine immune system. On the basis of the analysis of the mutual regulation mechanism between the nervous system, the endocrine system and the immune system, the disturbance processing method of the biological manufacturing system is proposed. Secondly, an organic manufacturing unit with monitoring and scheduling power is designed, and a class biologic system is constructed. The mechanism of system disturbance detection and diagnosis is made. Then the corresponding disturbance processing strategy is given for different types of disturbance, and the implementation steps of the strategy are introduced in detail. Finally, the feasibility and effectiveness of the proposed method are verified by contrast experiments. The simulation platform of the biologically based manufacturing system is developed.5. First, based on the biologically based manufacturing system In the framework of the system, a physical simulation platform is built, and the protocol of the hormone like communication between the organic manufacturing units is designed. Secondly, the corresponding software simulation platform is developed and the main functional modules of the platform are designed. Finally, the experiment is carried out on the developed biological manufacturing system simulation platform to verify the immunity based on the neuroendocrine exemption. The feasibility and effectiveness of dynamic scheduling method for biologically based manufacturing system with epidemic regulation mechanism is discussed.
