摘      要：Sugarcane crop occupies an area of about 23.78 million hectares in 103 countries,and an estimated production of 1.66 billion tons,adding to this volume more than 6%to 17%concerning residual biomass resulting from *** destination of this residual biomass is a major challenge to managers of *** are at least two alternatives which are reduction in residue production and increased output in electricity *** two conflicting objectives are mathematically modeled as a bi-objective *** study developed a bi-objective mathematical model for choosing sugarcane varieties that result in maximum revenue from electricity sales and minimum gathering cost of sugarcane harvesting residual *** approach used to solve the proposed model was based on theε-constraints *** were performed using real data from sugarcane varieties and costs and showed effectiveness of model and method *** experiments showed the possibility of increasing net revenue from electricity sale,i.e.,already discounted the cost increase with residual biomass gathering,in up to 98.44%.
