| The Manufacturing Execution System(MES)is a manifestation of the application of modern information technology in workshop management.It is an information management system that serves the entire process of production between the on-site shop floor control and the upper production management system.In recent years,the concept of Industry 4.0 proposed by Germany and the “Made in China 2025” plan formulated by China have both promoted industrialization through informationization and promoted the sound and rapid development of modern manufacturing as a priority issue for development.The MES system is The best platform and good vehicle for this subject.However,due to the fact that China’s discrete manufacturing informatization is just at the initial stage,in the general environment,especially the machinery manufacturing industry,for example,the production data collection volume is large and the processing is complicated.The workshop scheduling and scheduling operations are complicated and inefficient;the work coordination is difficult;The management data collection requirements are very high;the management difficulties such as real-time monitoring of the on-site job conditions on the shop floor cannot be achieved.In the process of reading a large number of documents and personally participating in the MES implementation process of related prototype companies,this paper adopts a combination of theoretical research and practical exploration.First of all,it studies the MES system from a macro perspective,and uses Wuhu TY as a research object,combining TY.The company’s production characteristics and MES requirements,from the micro point of view to face the MES system for the design of the program and the layout of system functions,and related technologies in the application process such as production scheduling,information integration,data acquisition and processing,etc.Described.The main work includes:(1)Introduce the production dilemma encountered by discrete manufacturing companies and the importance of enterprise information management.The necessity of using MES system is summarized and summed up by combining the operation status of TY company’s lithium battery production line and the theory of MES system.(2)Through the mastery of TY company’s production management status,it analyzes the basic requirements and functional requirements of the MES implementation of the discrete manufacturing industry represented by TY,and arranges the overall architecture and business process of the system,and completes the network topology at the same time.Structure and system platform construction.(3)Concentrate on the key technologies in MES implementation,mainly include: 1.Establish the workflow model(distribution business process model and scheduling control information flow model)and the mathematical model of the scheduling problem by understanding the flow of the shop scheduling process,and After comparing the scheduling algorithms,a genetic algorithm is selected to solve the specific production scheduling problem of TY.2.After comprehensive analysis of the characteristics of the existing data collection methods and the operating requirements of the TY company’s lithium battery production process,select RFID radio frequency identification technology to achieve MES data collection and collation.3.Through the establishment of an intermediate database and the integration of major businesses such as order fulfillment,quota picking,and warehouse completion,information integration between MES and ERP systems is finally achieved.(4)Detailed design of the MES system of TY Inc.,including the selection of the latter to complete the development of the system after analyzing the overall advantages and disadvantages of the B/S and C/S structures;the difference between the conceptual structure and logical structure of the MES database Design and display some database tables;define the main functions of enterprise MES such as production scheduling,plan management,and process outsourcing management.Briefly introduce the implementation environment of TY’s MES software,present part of the login and operation interface and complete the test of the system.(5)This article will play a certain role in the research and application of discrete manufacturing MES system. |
