【摘要】：据统计，在我国大型水电开发工程建设过程中，，其所需要的工程物资与机电设备等的采购成本约占工程总投资的40%~70%，在这样的特殊条件下，采购部门在对整个工程建设的成本控制、进度及质量保障等上起到了至关重要的作用，因此，需通过科学合理的采购决策方法，研究水电开发工程背景下业主统供物资供应商的选择，这对于水电开发工程是非常有意义的。本文建立了多阶段的物资采购决策模型。模型将不同阶段的供应商选择、绩效评价及采购量分配三个部分结合起来。在供应商选择问题中，研究分为供应链规划期与供应链构建期两个阶段，规划期选取待选供应商集合，构建期进行供应商招标，选中入选供应商；在供应商绩效评价问题中，对选择出的物资供应商相应的进行阶段性的绩效评价，记录绩效结果，引入采购量分配模型；在采购量分配问题中，建立多周期多目标采购量分配模型，通过对历史供货轨迹分析，实现对未来采购周期相关数据的预测，进行多周期滚动的采购量分配。论文以雅砻江流域水电开发公司相关电站建设阶段物资供应为数据来源，对本文所提出的采购决策方法的应用进行研究，并与雅砻江公司实际采购状况相对比，分析发现，本方法选得的物资供应商与雅砻江公司实际招标选择情况一致，且在采购量分配时，成本目标权重较高时，采购量按照供应商报价优先分配给报价较低的供应商；采购价值目标权重较高时，采购量会优先分配给绩效评分较高的物资供应商。
[Abstract]:According to statistics, during the construction of large-scale hydropower development projects in China, the procurement costs of engineering materials and mechanical and electrical equipment needed by them account for about 40% of the total investment in the project. Under such special conditions, The purchasing department plays an important role in cost control, progress and quality assurance of the whole project. Therefore, it is necessary to adopt a scientific and reasonable purchasing decision method. It is of great significance for hydropower development to study the selection of supplier in the background of hydropower development project. In this paper, a multi-stage material purchase decision model is established. The model combines three parts: supplier selection, performance evaluation and procurement volume allocation. In the problem of supplier selection, the research is divided into two stages: supply chain planning period and supply chain construction period. The performance of the selected suppliers is evaluated periodically, the results of performance are recorded, and the procurement quantity allocation model is introduced, and the multi-cycle and multi-objective procurement volume allocation model is established in the procurement volume allocation problem. By analyzing the track of historical supply, we can predict the relevant data of the future purchasing cycle, and carry on the multi-cycle rolling purchase quantity distribution. Taking the material supply of Yalong River Basin Hydropower Development Company as the data source, this paper studies the application of the purchasing decision-making method proposed in this paper, and compares with the actual purchasing situation of Yalong River Company. The material supplier selected by the method is consistent with the actual bidding selection of Yalong River Company, and when the cost target weight is high, the purchase quantity is first allocated to the supplier with lower quotation according to the supplier quotation. When the target weight of purchasing value is high, the quantity of purchase will be assigned to the material supplier with higher performance score.
