Hierarchical synthesis of multi-level design parameters in assembly system

This paper proposes a novel methodology to optimize heterogeneous design tasks with competing parameters. It is based on the principle of design parameter sensitivity, taking into account the notion of robustness at an early phase of process design. The aim is to improve the quality of the assembly system in order to make it less sensitive to variations/changes of design parameters. The methodology is based on the development of: (i) analytical design task function; (ii) inner- and outer-sensitivity; (iii) design parameter sensitivity; and (iv) decision making module. The methodology is demonstrated using results involving an automotive door assembly.
