【摘要】：随着中国汽车销量的不断提升,中国汽车零部件制造业也实现着每年20%以上的增长。同时,伴随着信息时代的发展,社会的进步,竞争的激烈,越来越多的汽车零部件公司觉察到仅仅通过人工管理采购流程是不行的,因为不仅会浪费很多的人力,还会浪费大量的纸张木材,重点是随着业务量的增多,出现数据错漏的情况逐渐增多,员工工作效率也逐渐下降。众所周知,IT技术可以有效支持企业内部运营,网络服务公司的首席信息官米歇尔·胡格斯先生认为使用各种新技术对有效地运营供应链是必要的[1]。同时,以自身业务过程的规范化和自动化来提高整体效率也是非常必要的。面向制造业的通用系统凭借自身自动化管理上的优势,得到了汽车零部件制造业公司的广泛应用。面向制造业的通用系统,是基于产品数据管理的一款管理信息系统。该系统将实际业务流程信息化,统筹产品的全部信息,确保产品信息的一致性与安全性,从而实现公司业务过程的规范化和自动化。目前,汽车零部件制造业中还是有问题,例如采购的一些基础结构设计还是缺少约束,业务之间的配合还是很不理想,没有在早期就与供应商建立良好的合作伙伴关系等等问题都导致了生产产品的总成本提高、生产产品的时间周期变长、向市场投放产品的时间变多、库存增多或者缺货断档和缺少对供应链上的可预测性[2]。在以上这些问题的基础上,汽车零部件行业基于精益求精的思想,在这10多年的迅速发展中,采购信息化的发展趋势相当明显,逐步接近国际水平。所以,采购管理基本是汽车零部件制造业的重点。因此,基于面向制造业的通用系统的采购流程的计算机化的设计与实现引来了很多学者的关注。本文是根据长春某汽车零部件制造业公司的实际需求出发,目标是采购流程的设计与实现。首先是对面向制造业的通用系统的相关介绍,基本概念和主要功能,采购流程的业务分析,功能性分析和非功能性分析,得出采购流程的设计目标;其次是采购流程的架构设计,包括关键技术,采购管理的基本流程图,基础数据,权限配置,用例图模型和通信功能,还介绍了采购流程设计基于通用系统结构的工作流和权限管理;然后介绍了采购流程的功能设计,包括开发平台和工具,基于的工作流的类设计和数据库设计,基于的权限管理的数据库设计,采购流程的类设计和数据库设计;最后介绍了采购流程的实现和测试,通过建立测试用例对相关模块的测试和模块实现结果的展示,全面的论述了采购流程的设计实现情况。
[Abstract]:With the continuous improvement of China's auto sales, China's auto parts manufacturing industry has also achieved an annual growth of more than 20%. At the same time, with the development of the information age, social progress, fierce competition, More and more auto parts companies are finding it impossible to manage the purchasing process manually, because it will not only waste a lot of manpower, but also waste a lot of paper and wood, with the emphasis on increasing the volume of business. The number of data errors is increasing and the efficiency of employees is declining. It is well known that IT technology can effectively support the internal operation of the enterprise. Michael Huggs, chief information officer of Web Services, believes that the use of new technologies is necessary for the efficient operation of supply chains [1]. It is also necessary to improve the overall efficiency by standardizing and automating their own business processes. The general system for manufacturing is a management information system based on product data management. The system informationization the actual business process and coordinates all the information of the product. Ensure the consistency and safety of product information to standardize and automate the company's business processes. At present, there are problems in the automotive parts manufacturing industry, such as the lack of constraints on some infrastructure designs for procurement. The cooperation between businesses is still not ideal, and the problems of not establishing good partnership with suppliers at an early stage have led to an increase in the total cost of producing products, and the time period for producing products has become longer. More time has been put on the market, more inventory or out of stock, and a lack of predictability in the supply chain [2]. On the basis of these problems, the automotive parts industry is based on the idea of excellence. In the rapid development of more than 10 years, the trend of procurement informatization is quite obvious, gradually approaching the international level. Therefore, procurement management is basically the focus of automotive parts manufacturing industry. The computerization design and implementation of purchasing process based on general manufacturing system has attracted the attention of many scholars. This paper is based on the actual demand of a Changchun automobile parts manufacturing company. The goal is to design and implement the purchasing process. Firstly, it introduces the general manufacturing oriented system, basic concepts and main functions, business analysis of purchasing process, functional analysis and non-functional analysis. The design objectives of the procurement process are obtained, followed by the architecture design of the procurement process, including the key technologies, the basic flow chart of the procurement management, the basic data, the authority configuration, the use case diagram model and the communication function. This paper also introduces the workflow and privilege management of purchasing process design based on general system structure, and then introduces the function design of procurement process, including development platform and tools, class design and database design based on workflow. The database design based on authority management, the class design and database design of purchasing process are introduced. Finally, the realization and test of purchasing process are introduced. The design and realization of purchasing process are discussed in detail.
