A Research on Integrated Optimization of Resilient Supply Chain Network Considering Risk-averse Behavior

The design and operational strategy optimization of resilient supply chain network under multi-dimension risk environment is focused on, with decision makers′ risk-averse behavior considered in the utility function, stochastic scenarios used to simulate the multi-dimension risk environment and nonlinear shortage penalty cost function used to restrict the shortage, which assures the resilience of the supply chain network under multi-dimension risk environment. Based on the process above, a nonlinear mixed integer stochastic programming model is built. The piece-wise linearization approach and SAA (sample average approximation) solution method are used to solve the nonlinear optimization model. The effectiveness and practical value are tested through a case study and sensitivity analysis.
