Abstract

Growers of processed oranges attempt to maximize on tree returns by harvesting fruit when pounds-solids per acre near their maximum and harvest costs near their seasonal low. The actual harvest date for a specific block, however, is set in conjunction with processor objectives. Processors attempt to maximize returns by scheduling fruit inputs to fill plant production capacity, minimize processing and storage costs, and maintain quality parameters. Operational capacity and inventory management decisions within each processing firm govern allowable harvest and processing schedules that strive to meet optimal plant operation goals. Overlaying both grower and processor objectives are the capacity limitations and cost of hand-harvest crews. Recent developments in mechanical harvest systems have the potential to improve harvest labor productivity, allowing increased freedoms during harvest and increasing in the daily capacities. This paper discusses the grower's optimal harvest window, the processor's optimal production window, and the implications of maximizing the combined returns of both growers and processors.
