| Abstract:
Our research has focused on the development of a crop growth model, and its incorporation into an organizational and operational planning model for the greenhouse production process. In Part I., an outline of the planning model of the greenhouse production process, which currently incorporates a plant production model, space planning and economic components, and will include components for labor, device and materials utilization, and space optimization, will be presented. The components of the model are organized into a hierarchical format as proposed by Challa et al (1985). Part II. consists of a detailed description of a crop growth model for the single truss production system which can relate the total available photosynthetic photon fluence (PPF) to both crop timing and crop yield. It produces a production schedule, allocates greenhouse growing space and predicts the quantity and value of plant yields for continuous tomato production. The current model has been tested and verified. Additional refinements are proposed. | |
