[Abstract]:In order to control the adverse effects of large-scale emergencies in a timely and effective manner, the characteristics of uncertainty in the requirements of various emergency materials in the emergency response system are considered. A multi-objective-two-stage temporary distribution center location and emergency resource scheduling model is established to minimize total cost and total time. The relative robust optimization method is used to solve the model, and interval estimation is used to describe the uncertain factors, and the robustness and optimality of the disturbance coefficient and control parameter adjustment model are introduced. Numerical results show that the proposed model can effectively solve the problem of constructing emergency resource scheduling network under uncertain demand and can ensure good robustness of emergency decision. Finally, through the analysis of the results of the target values under the single-objective and multi-objective models and the target values under different control parameters and disturbance coefficients, it is further verified that the model accords with the actual situation of emergency response.
