[Abstract]:The fierce market competition requires the manufacturing enterprise to realize the rapid response to the continuous fluctuation of the market. At this time, the emergence of the ReconfigurableManufacturing System (RMS) theory, which takes into account the unit production efficiency and the discrete production flexibility, is the development of the production capacity evolution based on the adjustment of the manufacturing resource allocation. Support is provided, which provides a new idea for the dynamic change of manufacturing system in the process of rapid response to manufacturing. As the manufacturing enterprises are increasingly changing to the multi variety and mass production mode, the RMS research, which is biased on the static phase manufacturing system planning, has been difficult to support the dynamic and continuous changing manufacturing system. Therefore, this paper aims at realizing the continuous and dynamic optimization configuration for manufacturing execution process, taking the resource reconfiguration features as the starting point for the operation scheduling and scheduling, studies the theoretical method and implementation technology of the combination of production scheduling and RMS, and promotes the transformation of RMS to the level of manufacturing execution. On the basis of this idea, this paper studies the reconfigurable manufacturing system oriented to the manufacturing execution process, launches the systematic research on the basic theory of continuous reconfiguration scheduling and its implementation method, and opens a practical work to support the continuous reconfiguration and evolution of the manufacturing system. It also validates the research results in combination with the actual project application.

1, based on the multi variety variable mass production model, this paper systematically analyzes the reconfiguration requirements of manufacturing execution oriented manufacturing system adapting to the dynamic production environment, and takes the continuous reconfigurable scheduling method as the core method to realize the new reconfigurable manufacturing system, and establishes the technical system, function model and service of the manufacturing system reconfiguration scheduling. The process is the three key technology of refining the progressive reconstruction of the manufacturing unit, the running water discrete mixed reconfiguration scheduling and the production resource dynamic reconfiguration and scheduling driven by the production disturbance.
2, according to the continuous adjustment demand of manufacturing unit oriented manufacturing units, the progressive reconstruction technology of manufacturing unit is studied. The problems of similar clustering, load balance, resource sharing and inheritance adjustment in the process of manufacturing unit construction and reconstruction under the current production mode are analyzed, and the system based on unified reconfiguration constraints and targets is established. In order to support the initial construction of manufacturing units, the clustering analysis method considering logistics costs is studied to support the initial construction process of the manufacturing unit, and a method of dividing the manufacturing unit based on the reduction of the number of tasks across the unit and the negative load of the equilibrium unit is established. In the process of continuous adjustment of manufacturing resources, a configuration adjustment method for manufacturing cells based on inheritance strategy is established.
3, based on the characteristics of the coexistence of multi variety and batch production, the reconfigurable scheduling technology for the mixed operation type is studied. The continuous production in the unit and the problem of the resource sharing inside and outside the unit are analyzed, and the integrated operation type reconfiguration scheduling is established. In the framework, a hybrid reconstruction scheduling algorithm based on immune genetic algorithm is studied. In order to guarantee the formation of pipelined production mode in the manufacturing unit, a non waiting continuous production guarantee method based on the pressing part buffer is established, and the manufacturing resource sharing mode is analyzed, and the manufacturing resources based on the minimum manufacturing cost vaccine technology are established. Enjoy the way.
4, in view of the rapid response of diversified production disturbances in the process of manufacturing execution, the dynamic reconfiguration scheduling technology of manufacturing resources is studied. The requirements for the unified processing of the disturbances in the dynamic reconfiguration scheduling under the complex dynamic production environment are analyzed, the conflict between the rescheduling efficiency and stability, the disturbance response of the hybrid operation type, and the response of the dynamic reconfiguration and scheduling in the complex dynamic production environment are analyzed. As well as the problem of resource sharing under the influence of production disturbance, the dynamic reconfiguration scheduling framework of manufacturing resource driven by production disturbance is established, and the dynamic reconfiguration scheduling algorithm based on ant colony algorithm is studied. The modular production disturbance of four basic processing methods is established for the multiple disturbance types in the dynamic reconfiguration scheduling. In order to solve the problem of rescheduling and resource sharing, a comprehensive rescheduling target based on the delivery period and the adjustment of process equipment is set up, and the response method of production disturbance based on tolerance is given in response to the tolerance of production disturbance.
5, based on the requirements of manufacturing enterprises, the continuous reconfiguration and scheduling system of manufacturing system is designed and developed, and the research results of this paper are demonstrated in combination with specific project application research.
