The aim of the research was to make a simple model which can help producers when starting the greenhouse production system. Based on the chosen plant production and available production area, the model suggests which type of greenhouse farmers should, as well as the optimal technical systems and area for further expansion. The control of the model flow was carried out in the MS Excel program. During the testing phase, it was concluded that the MS Excel is not so good in programming so Quick Basic version 4.5 was used and it appeared simpler and easier for programming. The results show that the model is very suitable for producers, to whom adequate solutions of the greenhouse production systems can be suggested, based on its elementary idea ...
