【摘要】:航空发动机结构复杂,零部件众多,质量可靠性要求极高,其原材料及零部件的质量及采购成本将直接影响发动机的性能及成本。 论文针对某航空发动机企业Enterprise Resource Planning(以下简称ERP)系统在采购供应中的应用现状及存在的问题,,以ERP系统提供数据为依据,首先运用多种工业工程方法对其库存占用进行详细分析,确定库存占用最大的关键物料种类,然后从物料分类方法和库存控制几个方面对企业采购供应进行改善,最后结合企业供应链环境,构建了战略供应商评价体系及采购绩效评价体系,并予以实施验证。 论文主要研究工作如下: (1)介绍了企业的采购供应体系,对ERP在企业采购供应中的应用现状进行了简述,最后分析了企业采购供应存在的问题及改善点; (2)基于企业ERP系统中物料的库存数据及原有物料分类方法,运用排列图、饼图、折线图及分层法对不同类物料的账龄分布进行了统计分析,基于分析结果,从物料分类方法、库存控制模型、供应商管理库存等方面提出了优化改善方案,并选择典型物料进行了优化改善实施验证; (3)基于上述分析结果,运用问卷调查及层次分析法构建了战略供应商综合评价体系,运用该体系对企业现有供应商进行评价,结果验证了该体系的有效性和可行性。 (4)运用SWOT法与战略地图分析了企业战略目标,采用鱼骨图及头脑风暴法分析造成企业当前采购绩效低的原因,从而确定了初步KPI指标;进而确定平衡计分卡指标;通过专家小组打分,运用古林法计算出各项指标权值,构建了完整的具有KPI指标特征的平衡计分卡采购绩效评价体系,应用案例验证了该体系的有效性。 论文研究工作一定程度上实现了对企业采购全过程的监督和管理,对航天企业采购成本的控制,采购供应绩效的进一步提升具有一定的借鉴及参考意义。
[Abstract]:The structure of aeroengine is complex, the parts are numerous, and the quality and reliability of the engine are very high. The quality and purchasing cost of the raw materials and parts will directly affect the performance and cost of the engine. This paper aims at the application status and existing problems of Enterprise Resource planning system in a certain aero-engine enterprise, which is based on the data provided by ERP system. Firstly, the inventory occupation is analyzed in detail by using a variety of industrial engineering methods to determine the type of key materials that occupy the largest amount of stock, and then the procurement and supply of enterprises are improved from several aspects of material classification and inventory control. Finally, a strategic supplier evaluation system and a procurement performance evaluation system are constructed and verified in the enterprise supply chain environment. The main research work of this thesis is as follows:. 1) this paper introduces the purchasing supply system of enterprises, briefly introduces the application status of ERP in enterprise procurement supply, and finally analyzes the existing problems and improvement points of enterprise procurement supply; Based on the inventory data of materials in enterprise ERP system and the classification method of original materials, this paper makes statistical analysis on the aging distribution of different kinds of materials by using arrangement diagram, pie chart, broken line diagram and stratification method. Based on the analysis results, the method of material classification is presented. In the aspects of inventory control model, supplier management inventory and so on, the optimization improvement scheme is put forward, and the typical materials are selected to carry out the optimization improvement implementation verification; 3) based on the above analysis results, a comprehensive evaluation system of strategic suppliers is constructed by questionnaire survey and analytic hierarchy process (AHP). The effectiveness and feasibility of the system are verified by using the system to evaluate the existing suppliers in enterprises. 4) using SWOT method and strategic map to analyze the strategic goal of the enterprise, using fishbone map and brainstorming method to analyze the reasons for the low purchasing performance of the enterprise at present, so as to determine the preliminary KPI index, and then to determine the index of the balanced scorecard. Through the expert group scoring, using the ancient forest method to calculate the weights of each index, a complete performance evaluation system of the balanced scorecard with the characteristics of KPI index is constructed, and the effectiveness of the system is verified by a case study. To a certain extent, the research work of this paper has realized the supervision and management of the whole process of enterprise procurement, which has certain reference and reference significance to the control of procurement cost and the further improvement of procurement and supply performance of aerospace enterprises.
