Companies compete in different markets with different products. To survive in these markets with the goods and services they produce and to make a reasonable profit, companies need to be competitive. Competition can be based, among other things, on price or quality, with the focus on creating added value for the customer. The allocation of available resources is therefore an essential element in achieving competitiveness. The changes in the horticultural sector in Germany highlight the need for analysis and modelling to provide companies, consultants and political decision-makers with an economic assessment of the competitiveness of the horticultural sector and to enable forecasting. In addition, alternative courses of action should be presented to support strategic and operational planning at micro and macro levels.
