Embodiments of the present disclosure relate to a method and apparatus for optimizing performance of a robotic cell. The robotic cell comprises at least one workstation and at least one robot. The method may comprise 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. With embodiments of the present disclosure, it is possible to perform performance optimization of the robotic cell on the sensitive workstation regarding to the sensitive factor, and thus it may efficiently determine an improved cell layout which may achieve performance improvement.
