Different production systems are being assessed with regard to machine capacity, machinery costs and timeliness costs. Timeliness costs are those costs that can have an impact on the choice of machine capacity and machine size. Timeliness costs are caused by losses of quality or quantity when a field operation such as sowing or harvesting is not performed at a time that would maximise the value of the crop.
One part of our research is to estimate the timeliness costs for different operations. Optimisation of machine systems and choice of machine capacity is conducted using models based on discrete event simulation or linear programming.
