Design of a biofuel supply network under stochastic and price-dependent biomass availability
提出了一个利润最大化的生物能源供应链战略设计框架，考虑生物质价格响应和产量不确定性，通过两阶段随机整数规划模型和L-shaped算法求解，并在德克萨斯州案例中展示了生物质与生物燃料价格关系及最优网络设计。
This article presents a framework for profit-maximizing strategic bio-energy supply chain design by taking into account variability in biomass as a response to price set as well as uncertainty in biomass yield. We present our model as a two-stage stochastic integer program for a multi-period integrated design of a network in which the here-and-now strategic decisions include biorefinery locations and size as well as base biomass price. To efficiently solve our model, we suggest an L-shaped-based algorithm along with a Sample Average Approximation approach. Finally, we demonstrate our results in a case study in Texas using realistic data. Within our framework, we present the relationship between biomass and biofuel price, as well as the optimal network design for the biofuel producer.
