摘要: 本文以并行项目多周期钢铁采购问题为研究对象,选取某时间段内上升趋势的钢铁历史价格数据为样本,通过平稳性检验、纯随机性检验和季节性分析处理,建立钢铁价格的时间序列预测模型,结合钢铁采购成本与融资成本的采购模型得出并行项目多周期钢铁最优采购策略。研究结果表明,预测模型和采购模型可以解决钢铁价格为上升趋势时的并行项目多周期钢材采购与库存管理问题,在不同的融资利率条件下其相应的采购策略比其他策略节约成本。

Abstract: Taking the concurrent project multi-period steel procurement problem as the research project, this paper establishes steel price time series prediction model through the stationarity test, pure random inspection and seasonal analysis processing by selecting the increasing steel historical price data in a certain period as sample. Then combining steel ordering cost with financing cost in an order model, the paper finally gets optimal strategy for concurrent project multi-period steel procurement strategy. Research results show that the prediction model and purchasing model can solve concurrent project multi-period steel procurement and inventory problems under the condition of increasing prices, and compared with other strategies, the corresponding purchasing storage strategy can save cost under the condition of different financing rates.

Key words: supply chain management; price forecasting; time series; concurrent project, multi-period steel procurement
