[Abstract]:With the function of the hydraulic cylinder and the diversification of the performance requirement, the production mode of the hydraulic cylinder manufacturing enterprise has gradually changed from the mass standardized production to the small batch customized production, and the change of the production mode has increased the difficulty of production management. Especially for the basic parts manufacturing workshop, many kinds of parts, many specifications, great differences in process flow have been the important factors that can not improve the productivity of the workshop. The emergence of manufacturing execution system (Manufacturing Execution System,MES) provides a fast response flexible and fine standard manufacturing environment which effectively shortens the production cycle improves the production efficiency and reduces the production cost. Based on the analysis of the present production situation of the hydraulic cylinder base parts manufacturing workshop, the MES of the workshop is studied and designed in this paper. This paper analyzes the characteristics of the production process of the hydraulic cylinder basic parts manufacturing workshop, aiming at the existing production problems and management drawbacks of the workshop, designs the overall MES solution of the part manufacturing workshop based on the scheduling module and the production scheduling module. In order to solve the scheduling difficulties caused by complex and changeable order planning, a systematic scheduling module is designed based on group technology. Sequencing realizes the transformation of production mode from small batch to large quantity. According to the characteristics of part process route and the situation of workshop resources, a design scheme of production scheduling module is proposed, which includes two parts: scheduling calculation layer and scheduling control layer. The scheduling layer based on hybrid genetic algorithm is the core of this module. Taking Visual Studio 2010 as the development platform, the development and design of MES for hydraulic cylinder basic parts manufacturing workshop are carried out. The system has been applied in the workshop production and achieved the expected design goal. It can effectively improve the workshop productivity, shorten the production cycle and reduce the production cost. The research results in this paper have certain reference value for discrete manufacturing workshop with the same production mode.
