Abstract
FruitSim is a fruit growth simulation system that is based on the PEACH model of Grossman and DeJong (1994). It has been separated into three layers: graphical user interface (GUI), error handling and initialisation, and the functional core.
The functional core has been redesigned in an objectoriented fashion so that parts can be exchanged.
The aim of the design is to enable a stepwise refinement of the system to add new knowledge of management systems without compromising robustness and stability.
FruitSim is not only a system that calculates attainable yield under optimal conditions but also considers yield restricting factors.
The Swagman/Destiny soil model has been integrated to describe possible limitations from the soil.
The effects of soil salinity and soil water stress are described with this part of the model, however, implementation is not yet finished.
The interaction between the two models will be kept very simple; that is, a lack of nutrients and water decreases the potential assimilation.
This simplification has been chosen to keep testing to a minimum.
The aim of the design is to separate the different parts and to keep interactions simple in order to easily develop improvements and add or exchange model parts.
Thus, FruitSim has the potential to portray a multitude of factors in orchard management, to include other areas such as economy, to describe scenarios, and to support management decisions.
