两级林木生物质供应链的决策与优化研究

Optimal Decision of Two-Level Forest Biomass Supply Chain Based on Game Model

研究了由收集中心与生物质炼油厂组成的两级林木生物质供应链的决策与优化问题。构建了由收集中心与生物质炼油厂组成的林木生物质供应链模型。分析了Stackelberg博弈与Nash协商博弈两种情形下的供应链决策问题,求解得出生物质销售价格、生物柴油产出量以及收集半径的最优值。最后,通过数值算例分析了单位面积林木生物质的产出量、市场容量及生物炼油转化率等系统参数对供应链最优决策的影响。

A two-level forest biomass supply chain was studied. Firstly,a supply chain model consisting of a collection center and a biomass refinery was constructed.Then the profit function of the collection center and the biomass refinery was given. Secondly,the decision-making under two different scenarios was studied.The optimal solutions of both scenarios were obtained.Finally,system parameters such as the output of forest biomass per unit area,market capacity and bio-refining conversion rate were analyzed by numerical results.
