The invention relates to a method for determining an optimum combination of sheet metal working installations (12a-12d) on a production site (10). The method involves multiple, in particular a multiplicity of, preferably all, possible installation combinations being created. This creation is preferably performed by a CLS module (CLS solver) (24). The created installation combinations are then ranked on the basis of at least one predefined optimization criterion (32). The optimization criterion (32) can be available in the form of the total installation costs and/or the total production time of the respective installation combination. The ranking can be carried out by means of an SMT module (SMT framework) (28). The SMT module (28) can additionally perform filtering on the basis of specific constraints (30), for example on the basis of a total production time that must not be exceeded for the respective installation combination. This allows well-trodden paths for the planning of a production site (10) to be left and unexpected optimum installation combinations to be found.
