[Abstract]:The manufacturing industry is the pillar industry of our national economy and the important symbol of the national competitiveness. The unit manufacturing system characterized by high efficiency, high flexibility, high quality and low cost has become the mainstream trend in the development of manufacturing industry. Unit construction is the basis of unit manufacturing, and the reasonable construction of the manufacturing unit is the modular production of the manufacturing system. Production, production system reengineering and the rapid application of rapid group technology provide the foundation. It is the core cell for rapid restructuring of manufacturing systems.
In view of the current needs of the development of the unit manufacturing system and the many problems existing in the current static and dynamic unit construction research (such as the shortage of precondition: without considering the actual situation of the original manufacturing system (machine equipment, human resources, etc.), a new method is proposed which is different from the static and dynamic units. The method of quasi dynamic unit construction, which uses the idea of phase construction to obtain the optimal scheme for each cycle unit. The thesis focuses on the theory, methods and implementation techniques of quasi dynamic unit construction, and establishes a unified paradigm (abstract function) for the construction of description units. The internal influence of construction is introduced into the construction of quasi dynamic unit. Finally, the mathematical model of the quasi dynamic dual resource unit is put forward, and the sensitivity analysis of the important parameters and the empirical analysis of the construction plan are carried out. The manufacturing strategy of the manufacturing system, the modular unit manufacturing, the group technology and so on is put forward. It provides basic technical support to promote the transformation and upgrading of China's manufacturing industry and the ability to respond quickly to market changes. It provides a substantial scientific contribution to the development of the theory and technology of the unit manufacturing system.
1) the theoretical study of the quasi dynamic element construction method. On the basis of the detailed analysis of the construction method of static and dynamic units, the basic idea and analysis method of quasi dynamic unit construction are put forward. The connection and difference of different types of unit construction methods are analyzed and analyzed, and the unified paradigm of the standardized construction method of the description unit is established.

3) the study of unit construction under quasi dynamic dual resource constraints. On the basis of the quasi dynamic element construction method, considering the division of equipment unit, the assignment of staff task and the effect of unit layout on the efficiency of the unit manufacturing system, the problem of unit construction under quasi dynamic dual resource constraints is studied, and the corresponding mathematical model is established. Then the appropriate solution method is studied.
4) case analysis. On the basis of the actual research and data analysis of the enterprise, the unit construction mathematical model under the quasi dynamic dual resource constraint is applied to the actual enterprise, and the original production mode is changed to the unit production mode, thus the material handling distance is greatly reduced, the quality of production, the efficiency of the staff and the whole unit system are improved. The efficiency of the system.
