In this paper, we describe a simulation model designed for studying orchard management in kiwifruit. It considers both fruit number and the distribution of fruit size at harvest in orchards in relation with some combined technical operations (plantation scheme, pruning, thinning and irrigation). The model attempts to account for fruit size variability by considering factors of variation taking place at different levels of organisation (flower, cohort of flowers, shoot, cane, vine, and plot). This is an important difference of design with the previous model of Doyle et al. (1989). We will examplify the use of the model by comparing several management options, using the cost of the technical operations and the expected value of the crop to build an economical criterion for evaluation
