1. A method for optimizing performance of a robotic cell, wherein the robotic cell comprises at least one workstation and at least one robot, the method comprising:

  • determining a factor and a corresponding workstation sensitive to the performance of the robotic cell by performing a sensitivity analysis on an initial cell layout for the robotic cell; and

    performing a performance optimization process on the corresponding workstation based on the determined factor to obtain an improved cell layout for the robotic cell;

    wherein the determining a factor and a corresponding workstation sensitive to the performance of the robotic cell comprises;

    performing a sensitivity analysis on the at least one workstation in the robotic cell regarding processing time and travelling time;

    ranking influences of the processing time and the travelling time on the at least one work station based on sensitivity analysis results; and

    determining one of the processing time and the travelling time and a workstation associated therewith which have the greatest influence on the performance of the robotic cell as the factor and the corresponding workstation sensitive to the performance of the robotic cell;

    wherein if the determined factor is processing time, a performance optimization process regarding a robotic cell pattern with scheduling is performed.
