Robust Assembly Processes as a Means of Achieving Systemability

The operating economy of automated assembly plants is directly related to their yield of OK parts. A hitherto unutilised opportunity for optimization consists in minimizing the scattering in the performance and fault characteristics of an assembly system. The key to this optimization is robust processes which can be created with the aid of various measures. Such measures include avoiding or compensating for variable parameters, or reducing and restructuring process chains. Reference data such as processability or the new systemability indices serve as a basis for assessing the robustness of assembly processes and in particular the complex interplay between them. It thus becomes possible to analyse factors influencing the boosts the efficiency assembly process and system, and to visualise them. By way of information feed back, control circuits which of existing assembly processes and process chains, and which are of use in the planning of new plants, can be built up.
