Abstract: Aiming at the problem that the innovative agents might suddenly discontinue collaboration which severely led to the structure crash and efficiency losses for Customer Collaborative Product Innovation Systems(CCPIS),a robustness analysis and optimization method of CCPIS was proposed based on complex network theory.The complexity of CCPIS was analyzed and a process model of robustness analysis and optimization was constructed.By considering the influence factors and methods of CCPIS robustness,the structural robustness,performance robustness and their metrics were defined.Robustness analysis scheme was proposed followed to random failure and target attack.Based on the percolation theory and optimization method,the optimization model of robustness under the constraint of cost was developed.A mobile phone manufacturing enterprise was taken as the case to verify the feasibility and effectiveness of the models and methods.
