摘要：

A crop growth model is used to investigate the optimal control problem associated with plant factory operation. The aim is to find the optimal age-dependent spacing between individual plants such that the profit of the farmer is maximized, in a situation when the production is quota limited. It is shown that the optimal spacing is such that the crop density is kept constant, corresponding to a constant value of the co-state variable in the associated optimal control problem.
