GWorkS-model simulates crop operations in greenhouses

Wageningen UR Greenhouse Horticulture and Wageningen University, group Farm Technology developed a simulation model for labour in greenhouses.

Global competition urges growers to continuously improve labour efficiency and to innovate crop operations in order to control labour costs and to offer appealing jobs and healthy work conditions in greenhouses. Computer simulation was used to find effects of organizational and technical modifications in crop operations. For this purpose the GWorkS- was developed.

The GWorkS model was applied in rose cultivation. It creates short-term work schedules and simulates the crop operations harvest, disbudding and bending of roses with a limited number of employees and trolleys. Several labour scenarios were simulated. A real labour management scenario as applied in a Dutch cut-rose grower company was used as a reference. Harvesting, disbudding and bending represent more than 90% of crop-bound labour time in the greenhouse. The model calculates the labour time in these processes well with 10.9 per s rose in the simulation and 11.5 s per rose in practice.
