It is technologically possible for a biorefinery to use a variety of biomass as feedstock including native perennial grasses (e.g., switchgrass) and agricultural residues (e.g., corn stalk and wheat straw). Incorporating the distinct characteristics of various types of biomass feedstocks and taking into account their interaction in supplying the bioenergy production, this paper proposed a multi-commodity network flow model to design the logistics system for a multiple-feedstock biomass-to-bioenergy industry. The model was formulated as a mixed integer linear programming, determining the locations of warehouses, the size of harvesting team, the types and amounts of biomass harvested/purchased, stored, and processed in each month, the transportation of biomass in the system, and so on. This paper demonstrated the advantages of using multiple types of biomass feedstocks by comparing with the case of using a single feedstock (switchgrass) and analyzed the relationship of the supply capacity of biomass feedstocks to the output and cost of biofuel.
从技术上讲，生物精炼厂可以使用各种生物质作为原料，包括本地多年生草本植物（例如柳枝稷）和农业残余物（例如玉米秸秆和麦草）。本文考虑了各种类型生物质原料的不同特点及其在供应生物能源生产方面的相互作用，提出了一个多商品网络流模型，以设计多原料生物质到生物能源产业的物流系统。该模型被制定为混合整数线性规划，确定了仓库的位置、收获团队的规模、每月收获/购买、储存和加工的生物质类型和数量、以及生物质在系统中的运输等。本文通过与使用单一原料（柳枝稷）的情况进行比较，展示了使用多种生物质原料的优势，并分析了生物质原料供应能力与生物燃料产量和成本的关系。
