According to the characteristics of industrial robots, user-customized configuration design pattern is showing to achieve rapid development of industrial robotics. In this paper, the definition of user-customized configuration design pattern is determined. The implementation approach of this pattern is given through introducing what role industrial robot stakeholders including suppliers, manufacturers, designers and users should play in the pattern. Then, the key technologies of implementation approach are introduced. Finally, system dynamics models are established for this design pattern and for traditional design pattern of industrial robots and are simulated by Anylogic simulation software. The simulation results prove that the proposed design pattern has better performances than traditional design pattern with regard to inventory and order response speed.
