A fitting system is provided that includes a plurality of fitting lines for fitting printed circuit boards with electronic components. A method for allocating printed circuit boards to the fitting lines includes: (1) determining requirements for fitting each of a plurality of printed circuit boards with allocated components; and (2) allocating the printed circuit boards to fitting lines under predetermined conditions by integral linear programming. Equipment families are determined for the fitting lines on the basis of the allocation, and the allocation is repeated until a criterion has reached a predetermined threshold. The criterion is established on the basis of the number of equipment families of the fitting lines, where an equipment family includes a quantity of different components with which a fitting line may be fitted in order to fit a predetermined amount of printed circuit boards.
