Precision engineering, which is concerned with repeatability and uncertainty in range of micrometers or sub-micrometers, is a typical application field of heterogeneous systems. A crucial issue of heterogeneous systems design in the context of precision is the optimization of coupling in the technical system. Current approaches of optimization of couplings are limited to the embodiment stage of the design process. Due to the fact that technological constraints are limiting the potential of optimization of couplings in this advanced stage of the design process this frequently results in significant changes of the system-structure. The first stage of the design process which allows an estimation of couplings in a technical system is the basic function-structure further on referred to as function-topology. This paper describes an approach to evaluate heterogeneous systems exemplified with a planar-positioning-system. Focussing on couplings between sub-functions this paper presents an algorithm which allows counting couplings between any two elements throughout all possible arrangements of heterogeneous sub-systems at an early stage of the design process.
