Research And Implementation Of ERP System For Additive Manufacturing Enterprises

In "made in China 2025",one of the primary goals is to substantially improve the level of manufacturing informatization by 2020.ERP system is the basis and key of manufacturing informatization.The existing standard ERP system in the market is designed according to the production mode of batch production of finalized products,which is difficult to meet the management requirements of additive manufacturing enterprises for customized production according to orders.The research object of this subject is a typical additive manufacturing enterprise,which urgently needs to develop a set of ERP system that not only meets the current business needs,but also is suitable for long-term development,solves the existing problems of enterprise management,and improves the core competitiveness of the enterprise.For this reason,this paper designs and develops the ERP system according to the production characteristics and business requirements of the enterprise,and tests the developed system to verify that the system functions meet the needs of users.The specific work is as follows:First of all,it analyzes the characteristics of additive manufacturing and production management as well as the current situation of informatization,summarizes the existing problems of enterprise management,uses the object-oriented method to analyze the requirements of additive manufacturing enterprise ERP system,describes the participants and specific functions of each module of the system through UML use case diagram.Secondly,the overall design of ERP system is described from three aspects: function design,architecture design and database design.According to the demand analysis,ERP system functions are divided into eight modules: production management,purchase management,sales management,customer management,inventory management,project management,equipment management and personnel management.The functions,system architecture and database of the modules are designed in detail.At last,the paper puts forward the method of object-oriented development and modular development to develop ERP system.The interface layer uses the method of combining HTML,CSS,XML and JS.The middle layer uses the ORM framework to encapsulate the data model and business logic model.The data storage layer uses the open-source database Postgre SQL to store enterprise data.This paper summarizes the development core of ERP system,the development of business data and business logic,and the development of visual view,and forms a set of standard development template.By using this template,the development cycle of ERP system can be shortened,the development cost can be saved,the development interface can be unified,and the code readability can be enhanced.The ERP system including production management,purchase management,sales management,customer management,inventory management,project management,equipment management and personnel management function modules has been realized,and design the test case test ERP system,analyze the test results,verify that the functions of the system meet the needs of enterprise management,through the implementation of this system can achieve the purpose of integrating enterprise resources,standardizing business management,guiding production,the follow-up information construction of the enterprise can be based on this system.
