"Green manufacturing is the core issue that the manufacturing industry must adhere to, but also one of the important paths of sustainable development, it plays a decisive role in the equipment manufacturing industry and the national economy. With the continuous development of manufacturing technology, the reasonable establishment of manufacturing control system complexity has become a prerequisite for giving full play to the advantages of advanced manufacturing technology, and is also one of the research hotspots in the field of production operation management. To minimize the difficulty of enterprise management and improve enterprise efficiency in the development of automation and self-actualization, it is necessary to take system complexity as a consideration factor in layout evaluation in the stage of system layout design. In this paper, based on the study of the complexity of machining manufacturing system, on the basis of satisfying the green manufacturing and manufacturing process, the complexity of machining manufacturing system in the process of production organization is deeply studied. By measuring the complexity of different layout schemes, the layout of the factory is evaluated, and the optimal scheme is obtained. (1) By summarizing the considerations of equipment layout evaluation in previous studies, it is pointed out that it is necessary to evaluate equipment layout scheme through system complexity. Based on the previous research on the complexity of machining manufacturing system, it is proposed to measure the complexity of machining manufacturing system by the complexity of process, and then evaluate the difference of different equipment layout. (2) Through the analysis of the analysis sources of factors affecting processing and manufacturing, the research framework of the complexity of machining and manufacturing system is proposed. On the premise of considering the complexity of the process, the complexity of machining and manufacturing system in the process of production organization is studied. The measurement methods of the complexity of one person and many machines, the complexity of operation and the complexity of decision are given by comprehensively considering the problem of one person and many machines in the system. the problem of multi-type product processing and the behavior process of workers in the production process. By redefining the complexity of the machining and manufacturing system, the differences of the complexity of the production organization are considered comprehensively, and then the differences of equipment layout are evaluated. (3) Establish an evaluation model, and use developed a software to program the model and verify the results. (4) Combined with the case of the machining and manufacturing system of the main parts of the two-stage deceleration, using the developed software for plane drawing, using SOLIDWORKS for factory simulation planning, the two methods proposed above are applied in practice, and the results obtained by the two methods are compared and analyzed. It is reasonable to measure the complexity of machining manufacturing system by considering the complexity of manufacturing process and production organization process. Through the production case of reducer parts, the proposed method is applied to the evaluation cases of different layout forms of the mechanical processing and manufacturing system of the part, which provides an effective decision-making basis for selecting the optimal equipment layout scheme of the manufacturing system.
