【摘要】：近年来,随着汽车市场的竞争越来越激烈,为了改善自身的盈利能力,各大整车企业往往采取降低成本的方法来取得更高的利润。采购在降低成本方面正发挥着巨大作用。供应商选择是采购管理中的一项重要环节,所以选择合适的方法来选择供应商对于整车企业来说非常关键。本文首先对整车企业的物料基于Kraljic矩阵进行了分类,并分析了四大类物料(战略物料、瓶颈物料、杠杆物料和一般物料)的特点、相应的采购战略以及Kraljic矩阵物料分类的方法。其次将供应商评估指标结合整车行业的特点分为能力评估指标和项目评估指标两类,并详细介绍了运营状况、质量、物流、项目成本等指标的概念、计算方法以及评分等级。再次在分析物料特点的基础上,提出了不同的物料采用不同的供应商选择方法的方案,具体表现为:战略物料对应合意选择法,瓶颈物料和杠杆物料对应权重选择法(AHP法),一般物料对应成本选择法(NPV法)。同时进一步对其中的层次分析法的步骤和验证方法进行了详细的描述。最后选取G公司的案例对目前的供应商选择现状提出了优化意见并以温度传感器这一瓶颈物料的供应商选择为例对各个供应商评估指标进行评分,最终运用AHP法求出该项目满意的供应商。本文得到的结论是整车企业可以根据Kraljic矩阵的物料分类的不同,采用相对更有针对性的供应商选择方法可以有效提高整车企业的供应商选择的效率和可靠性。
[Abstract]:In recent years, with the increasingly fierce competition in the automobile market, in order to improve their profitability. The major automobile enterprises often adopt the method of reducing the cost to obtain higher profits. Procurement is playing a great role in reducing the cost. Supplier selection is an important link in the procurement management. So choosing the appropriate method to select the supplier is very important for the whole vehicle enterprise. Firstly, this paper classifies the material of the whole vehicle enterprise based on Kraljic matrix. The characteristics of four kinds of materials (strategic material, bottleneck material, lever material and general material) are analyzed. The corresponding procurement strategy and Kraljic matrix material classification method. Secondly, the supplier evaluation index combined with the characteristics of the vehicle industry can be divided into two categories: capability evaluation index and project evaluation index. And introduced in detail the operation condition, the quality, the logistics, the project cost and so on index concept, the computation method as well as the score grade. Again in the analysis material characteristic foundation. Put forward different materials with different supplier selection methods, the specific performance is: strategic materials corresponding to the preferred selection method, bottleneck material and leverage material corresponding weight selection method AHP). General material corresponding cost selection method / NPV method). At the same time, the steps and verification methods of AHP are described in detail. Finally, the case of G company is selected to optimize the current status of supplier selection and the bottle of temperature sensor is given. The supplier selection of neck material is used as an example to evaluate each supplier's evaluation index. Finally, the AHP method is used to find out the satisfied suppliers of the project. The conclusion of this paper is that the vehicle enterprises can be classified differently according to the Kraljic matrix. The efficiency and reliability of supplier selection can be effectively improved by adopting more targeted supplier selection methods.
