【摘要】：采购是企业管理中重要的一环——采购管理流程严密且固定，评估和认证都需要进行重重检测，查找新的产品、新型材料和信誉度高的供应商、搜集多方资料、开发新的材料源都是重中之重。由于原材料市场价格多变、品质状况参差不齐，为了确保采购低成本、高品质的材料，采购员要严格审查材料质量、制定采购计划、及时掌握市场变化、妥善和供应商以及其他部门的负责人沟通协商等。采购管理中需要进行大量的数据交换。目前国内外采购管理系统的开发人员追求的不二法则是：设计合理的数据库结构来保存数据信息，减少冗余数据表；搭建高效的程序结构平台来支持各种数据执行运行操作，尽量减少人员手工操作。本文主要工作是设计并实现一款采购系统，该系统是基于PDM开发的。产品数据管理简称PDM（Product Data Management），它是一种能够满足企业实现管理体系自动化、智能化、科学化和规范化等需求而诞生的新型的企业管理模式。在制造过程数据文档管理系统，，实现车间无纸化生产。它最主要的特点就是可以实时、精准的掌握变化的采购信息。借助网络和软件管理，实现实时掌握原材料市场价格和行情变化就成为了可能，进而就加速了急需物流的周转率、提高了服务质量、扩大了企业经营面，还能够减少因为材料统计程序繁杂而产生的各种问题。本文所设计的系统以软件开发过程为线索：先从软件开发环境开始，依次介绍了系统开发设计的详细过程，分别是系统数据库设计、各模块功能设计和实现以及具体的数据库连接过程、代码测试与系统调试等。该采购系统的功能模块主要有：系统权限的授权以及管理、系统原始数据输入存储、各模块数据的汇总以及修改、查询等其他操作。从而，实现对采购单下达、采购单审核、员工信息及供应商信息等实现全面、动态、及时的管理。通过相关实验及系统测试，该采购系统基本满足了采购行业的各种功能需求，该系统的实现使得企业的部门管理、库存管理、采购管理及供应商管理等工作实现了信息化、网络化，提高了企业的工作效率和管理水平。
[Abstract]:Procurement is an important part of enterprise management-purchasing management process is strict and fixed, evaluation and certification need to be heavily examined, new products, new materials and suppliers with high reputation are found, and various kinds of information are collected. Developing new sources of materials is a top priority. In order to ensure the purchase of low cost and high quality materials, buyers should strictly review the quality of materials, formulate purchasing plans, and keep abreast of market changes in order to ensure that the prices of raw materials are changeable and the quality of materials is not uniform. Communicate and negotiate with suppliers and other department leaders. A large amount of data exchange is needed in purchasing management. At present, the developers of procurement management system at home and abroad pursue the following principles: design reasonable database structure to save data information and reduce redundant data tables; Build efficient program structure platform to support all kinds of data execution operation, reduce the number of manual operation personnel as far as possible. The main work of this paper is to design and implement a purchasing system, which is based on PDM. Product data Management (PDM (Product Data Management),) is a new enterprise management model which can meet the requirements of automatization, intelligence, science and standardization of enterprise management system. In the manufacturing process data document management system, realizes the workshop paperless production. Its most important feature is to be able to real-time, accurate grasp of changing procurement information. With the help of network and software management, it is possible to grasp the market prices and market changes of raw materials in real time, thus accelerating the turnover rate of the badly needed logistics, improving the service quality, and expanding the business scope of enterprises. It can also reduce the variety of problems arising from the complexity of material statistics procedures. The system designed in this paper takes the software development process as the clue: starting with the software development environment, the detailed process of the system development and design is introduced in turn, which is the system database design. Each module function design and realization as well as the concrete database connection process, the code test and the system debugging and so on. The function modules of the purchasing system mainly include: authorization and management of system authority, input and storage of system raw data, summary and modification of data of each module, query and other operations. Thus, complete, dynamic and timely management of purchase order, purchase order audit, employee information and supplier information are realized. Through relevant experiments and system tests, the procurement system basically meets the various functional requirements of the procurement industry. The realization of the system makes the department management, inventory management, procurement management and supplier management of the enterprise information. Network, improve the efficiency of the enterprise and management level.
