Stochastic programming and simulation are also employed to solve bioenergy supply chain problems with uncertainty. Osmani and Zhang [4] developed a two-stage stochastic MILP for strategic and tactical decision making in a multi-feedstock bioethanol supply chain. Kim et al. [5] propose an integer stochastic programming model for a biorefinery network structure for single and multiple design scenarios. Sodhi and Tang [6] introduce a two-stage sto- chastic model for supply chain management under uncertainty by applying a stochastic mixed integer non-linear programming to determine the production topology, plant sizing, product selection and allocation and vendor selection. Simulation methods are important tools to monitor the behavior of complex real world systems. They are also useful to analyze the impact of variations in system parameters. Sokhansanj et al. [7] developed a dynamic in- tegrated biomass supply analysis and logistics model to simulate the flow of biomass from field to biorefinery. Climatic and opera-
