More than 50% of the cost to load, haul, and deliver a weekly supply of herbaceous biomass from temporary storage locations near the production fields to a bioprocessing plant (50 Mg/h average capacity, 24/7 operation) is from truck ownership cost. The management policy that a bioprocessing plant uses to schedule trucks determines the maximum number of trucks required and thereby, the total cost for the logistics system. Two different management policies, one based on travel time (Policy 1) and another based on the assignment of trucks to given sectors of the surrounding production base (Policy 2) was used to develop truck schedules. The logistic system was modeled as a discrete event simulation model, and the schedule was validated.
