Abstract: This paper discusses the automation or support system for decision making in greenhouses. This automation is practised in the form of a computer program which are governed by setpoints. The choice of setpoints for environmental parameters must be done by a reasoning process integrating the situation outside the greenhouses, and inside situation that will be managed in an advantageous manner ensuring a profitable, though safe combination of growth and development factors while keeping the energy spending within acceptable bounds and as low as possible.
