For scale cotton-picker operation, combination of production resources including field, machine,
and drivers, should be organized reasonably both in temporal and spatial dimensions. Xinjian Agri.
is such a scale cotton picking service company, which owns more than 400 cotton-pickers, hires
nearly 1000 personnel, and works for more than ten big farms each season. The total operation
area is about 90,000 ha. In this paper, a Cotton-picker Operation Scheduling & Monitoring System
(CPOSMS) was developed for Xinjian Agri. CPOSMS is a WebGIS and BeiDou based management
software, which includes four main function modules. Overall scheduling module aims to help the
company to create machine fleets for the farms based on operation demands and operation capacity.
A real-time evaluation model was studied to adjust the rationality. Local scheduling module is
to dispatch machines and personnel to form machine unit. Central navigating module is to guide
staff to specific field. Operation monitoring module is to monitor and analyze operation process.
Experiments in 2015 showed that the CPOSMS is the necessary tool for the company, and the
evaluation model and BeiDou based system can improve management efficiency.
