随着全球经济一体化的快速发展，化工欧亿·体育（中国）有限公司同质化竞争日趋激烈。尤其在国 家宏观经济调控和环境保护政策下，中华人民共和国国民经济和社会发展第十二 个五年规划纲要中，国家环境安全保护法提出要推动清洁能源生产模式和循环发 展经济模式，提高化工欧亿·体育（中国）有限公司排放标准，加强清洁生产管理评价指标，化工企业发 展面临的问题开始凸显。高排放标准和清洁生产要求，意味着化工企业环保投入 大幅增加，欧亿·体育（中国）有限公司面临洗盘和很多未知挑战。对企业采购管理而言，则需提高供应 商选择门槛和原材料采购标准，不断优化原材料采购策略，降低供应风险。AN 集 团虽然是老牌外商投资化工龙头企业，但同样面临市场竞争日趋白日化、企业成 本不断增加、原材料供应风险不断增加等问题。如何根据 AN 集团集中采购管理现 状，优化集中采购管理流程、发展战略合作供应商、降低采购成本和降低供应风 险，已经成为 AN 集团长远发展需要解决的迫在眉睫的问题。 本文将 AN 集团集中采购管理作为研究对象，通过对 AN 集团集中采购管理当 前所面临的集团采购流程执行不一致、多数使用分散采购模式、原材料成本高、 库存高、集中采购数据收集困难、供应商分散管理等问题进行深入剖析。从 AN 集 团全球采购管理架构变更、信息化系统数据共享、共享服务中心、库存成本控制、 采购风险预警和控制、供应商集团化管理等维度进行优化，制定出一套适合 AN 集 团发展的集中采购管理优化策略流程。 本文主要采用文献研究和理论与实际相结合的方法，通过对国内外相关理论 书籍和企业案例分析进行研究，结合 AN 集团当前集中采购管理流程中的问题与不 足，搭建了一套适合于 AN 集团集中采购管理的流程优化方案。从实际实施效果来 看，AN 集团集中采购管理模式得到有效实施、信息化系统全面高效运行、供应商 集中化管理成果明显、战略合作伙伴供应商明显增多、采购成本和库存得到有效 控制。AN 集团应变能力和抗风险能力明显提升，在激烈的市场竞争中保持竞争优 势，市场份额稳步上升，提升了 AN 集团的综合实力。 关键词：采购成本，战略合作，集中采购，流程优化湖 北 工 业 大 学 硕 士 学 位 论 文 II Abstract With the rapid development of global economic integration, homogenized co mpetition in chemical industry is becoming increasingly fierce. Especially in the national macroeconomic regulation and control and environmental protection polic ies, the People's Republic of China national economic and social development, in the twelfth five-year plan for national environmental security protection is put f orward to promote the development of clean energy production mode and the cir culation economic model, to improve the chemical industry emissions standards, i n order to strengthen the management of cleaner production evaluation index, the development of the chemical enterprise facing the problem began to highlight. High emission standards and cleaner production requirements mean that chemical enterprises have significantly increased investment in environmental protection, a nd the industry is faced with dishwashing and many unknown challenges. For en terprise procurement management, it is necessary to raise the threshold of supplie r selection and raw material procurement standards, constantly optimize raw mate rial procurement strategies, and reduce supply risks. Although AN Group is a lea ding foreign-invested chemical enterprise with a long history, it is also faced wit h increasing market competition, increasing enterprise costs and increasing raw m aterial supply risks. According to the current situation of centralized procurement management of AN Group, how to optimize the process of centralized procure ment management, develop strategic cooperative suppliers, reduce procurement co sts and reduce supply risks has become AN urgent problem to be solved for the long-term development of AN Group. This thesis takes the centralized procurement management of AN Group as t he object of study, and makes AN in-depth analysis of the problems currently fa ced by the centralized procurement management of AN Group, such as inconsiste nt execution of the procurement process of the group, most use decentralized pro curement mode, high cost of raw materials, high inventory, difficulty in collectin g centralized procurement data, decentralized management of suppliers and so on. Optimize the dimensions of AN Group's global procurement management structu re change, information system data sharing, Shared service center, inventory cost control, procurement risk early warning and control, and supplier group managem ent, and work out a set of centralized procurement management optimization stra tegy process suitable for the development of AN Group. This thesis mainly adopts the method of literature research and combination of theory and practice, through the study of relevant theoretical books at home a nd abroad and enterprise case analysis, combined with the problems and shortco mings in the current centralized procurement management process of AN Group, to build a set of process optimization scheme suitable for the centralized procure湖 北 工 业 大 学 硕 士 学 位 论 文 III ment management of AN Group. From the practical implementation effect, the ce ntralized procurement management mode of AN Group has been effectively impl emented, the information system has been fully and efficiently run, the centralize d supplier management results have been obvious, the strategic partner suppliers have increased significantly, and the procurement cost and inventory have been e ffectively controlled.AN Group's ability to adapt to changes and resist risks has been significantly improved, maintaining its competitive advantage in the fierce market competition, steadily increasing its market share, and enhancing its compr ehensive strength.
