An iterative procedure is presented to solve the process planning problem for robotic assembly systems. The procedure consists of two levels: Level 1—station loading and Level 2—operation scheduling. The main task is to select and load stations and to schedule operations so as to minimise the overall cost of the system with respect to several constraints: (i) time constraints to avoid the bottleneck as well as idle time due to given production ratio, (ii) transportation constraints to avoid returns of the processed assembly to the same station. The procedure is illustrated on the example of modernisation of the system for railcar sides assembly.
