锥形水泥杆成本计算模型及预测分析研究

Research on Cost Calculation Model and Prediction Analysis of Conical Cement Pole

摘要: 本文运用单根锥形水泥杆的成本计算模型，选择试点水泥杆品类的供应商采集主材成本、生产成本、经营成本等各项数据，运用回归模型计算出锥形水泥杆的合理价，借助皮尔逊相关函数、方差膨胀因子用以验证模型可靠性，并穿插比较分析法，针对合理价影响最大的主材成本进行深入分析，锁定混凝土、螺纹钢为主材成本的关键构成项。本文应用模型结论，提出适用于物资专业采购管理、策略优化的建议举措，进而达到提高水泥杆采购质效管理的总体目标。

Abstract: The paper uses the cost calculation model of a single conical cement pole, selects the suppliers of the pilot cement pole category to collect the main material cost, production cost, operating cost and other data, uses the regression model to calculate the reasonable price of the conical cement pole, verifies the reliability of the model with the help of Pearson correlation function and variance expansion factor, and intersperses comparative analysis. The cost of main materials, which has the greatest impact on reasonable price, is analyzed in depth, and concrete and rebar are the key components of the cost of main materials. Based on the conclusion of the model, the paper puts forward some suggestions and measures suitable for material professional procurement management and strategy optimization, so as to achieve the overall goal of improving the quality and efficiency management of cement pole procurement.
