摘要
开发和利用生物能源可以在一定程度上缓解我国面临的能源紧张的局面。为了实现对生物能源的精益开发,有必要研究生物能源供应链的优化设计问题。在考虑原材料产量约束、精炼厂生产能力约束和需求满足约束的基础上,建立了以追求生物能源供应链总成本最小化为目标的整数规划模型,通过CPLEX软件进行求解,最终决策精炼厂的选址、精炼厂的规模设计及其年产量,并确定原材料产地、精炼厂和需求地三者之间的供应关系和配送量。以辽宁省的数据为实际算例,验证了模型的有效性。在总成本中,精炼厂的生产成本比重最大,约为总成本的59%,而运输成本最小约为8%。在此基础之上进行了灵敏性分析,讨论了该模型在价格和需求发生变化时的不同表现。
The development and utilization of biomass energy can ease the tension of energy .For the lean development of bioenergy , it is necessary to study the optimal design of bioenergy supply chain .In consid-ering the raw material production constraints , refinery capacity constraints , and demand satisfaction con-straints , a mixed integer programming model is established to minimize the total cost of the bioenergy sup-ply chain .It is solved by CPLEX and the refinery location , the scale of refinery , and annual production of refinery are obtained .In addition, supply relationship and distribution quality among raw material suppler , refinery and demand are determined .The effectiveness of the model is demonstrated through a numerical case study based on data of Liaoning Province .The production cost of refineries accounts for the largest proportion , about 59%of the total cost , and the transportation cost for the smallest , about 8%.The per-formance of the model with various prices and demands is discussed .
