Residual Biomasses from agriculture and forestry activities are among the most promising renewable energy sources. To face the growing need of such resources for the energy producing industry the delivery of residual biomass fuels must be effectively enhanced compared to the current state. By help of the simulation software “Vensim DSS” ® (Ventana Systems Inc.) we developed a set of equations representing one biomass harvesting and supplying chain. The considered system, which has the Time step of one day and covers a time span of three years, is composed by three sub models which are related to: a) energy plant dimensioning; b) supply transport cost estimation; c) harvesting and conditioning operations cost estimation. Model output underwent to univariate and multivariate sensitivity analysis to check its behavior at changing of parameters’ values. Model behavior turns out to be quite robust at varying of the input parameters for all the considered variables: evaluation of behavior pattern measures showed that with reference to €/MWh primary energy equilibrium level is quickly achieved meaning that negative feedback loops become soon dominant in the system.
