自设采购点模式下最优采购策略研究——以枣庄十里泉电厂为例

Analysis on straw purchasing model based on the cost

在我国秸秆资源开发利用的起步过程中,秸秆资源的有效采购成为我国秸秆能源化亟待解决的重要"瓶颈"。论文基于山东枣庄十里泉电厂自己设立采购点进行秸秆采购的模式建立最小成本模型,针对不同采购点数设置下的成本进行分析,选择出最经济的采购点数;然后根据区域平分、选取中心点的原则确定采购点位置;最后测量出采购点到电厂的距离,通过fortran、excel等软件的计算和处理,得出最小成本和此成本下每个采购点的最经济秸秆采购量。由分析可得,枣庄十里泉电厂秸秆采购点确定为5个时,秸秆采购成本最低,文中也说明了各个点最优的采购量分配。本文的研究思路和基本方法可为我国的秸秆发电厂建立经济合理的原料采购模式提供重要参考。

The problem how to purchase straw effectively has become a important 'bottleneck' which needs to resolve urgently in the first process of straw's exploitation.The paper builds the minimum cost model based on the power plant's mode of purchasing by itself,analyzes The costs under different purchasing points,gets the best points number,then Calculates the optimal quantity of straw and the minimum.cost.The results show that when the Plant chooses to build 5 purchasing points,the cost is lowest.We can see the purchasing quantity of each points.The study method could provide useful references for a Plant to build one reasonable and economical mode to purchase raw material.
