[Abstract]:Manufacturing execution system (mes) is the application of modern information technology in workshop management. By transmitting information between the upper planning management and the bottom control layer of the workshop, it plays the role of connecting the preceding and the following, which is to realize the extension of information to the bottom of the workshop. Finally, the key to realize the full information integration of manufacturing enterprises. In the process of transforming our country from a big manufacturing country to a powerful manufacturing country, according to the characteristics of the actual manufacturing process, the research and development of mes is of great significance to improve the level of information technology in our manufacturing industry. It is also the need to advance the strategic goal of 2025 made in China. According to the characteristics of the reducer assembly process and the specific requirements of management and control, this paper has carried out a targeted manufacturing execution system research, on the basis of the research on the key problem, that is, the hybrid assembly scheduling problem. According to the theory and method of software engineering, the system is analyzed and designed, and the prototype system is realized. The main contents of this paper are as follows: firstly, starting with the analysis of the technical status and development trend of manufacturing execution system, the scheduling problem of mixed-flow assembly line in semi-open operation domain is studied. A mathematical model is established to minimize the overload time. In this paper, an improved particle swarm optimization algorithm based on penalty strategy is proposed, and the proposed improved particle swarm optimization algorithm is applied to solve the scheduling problem. Then, the functional modules of mes in assembly training workshop are analyzed, and the function structure of the system is designed in detail. The technology involved in the function modules such as human resource optimization, automatic material distribution, process document management and so on are screened, and the advantages and disadvantages of various technical realization methods are understood, combined with the actual requirements of mes system in assembly training workshop. Select appropriate implementation techniques for each function. Finally, according to the system requirement specification and the design specification of the system concept design stage, the mes system of the assembly training workshop is developed, and the mes prototype system of the assembly training workshop is constructed.
