Aiming at the problem of closed-loop supply chain network design in uncertain environment,a closed-loop supply chain network planning model is constructed with the goal of minimum network cost,carbon emission and loss of customer satisfaction.The polyhedral uncertainty set is used to describe the uncertain parameters,and a multi-objective robust optimization model based on polyhedral uncertainty set is established.An adaptive cuckoo search algorithm based on dynamic step size and dynamic discovery probability is proposed,and the group search strategy is introduced to increase the population advancement efficiency.Combined with the operation data of the case enterprise, the dynamic adaptive cuckoo search algorithm is used respectively.The superiority of the improved cuckoo search algorithm is verified by the dynamic adaptive cuckoo search algorithm and the non-dominated sorting genetic algorithm.Finally,in order to verify the robustness of the model,the polyhedron robust optimization model is compared with the deterministic model,the box robust optimization model and the interval polyhedron robust optimization model to verify the effective inhibition of the proposed model to the uncertain disturbance.
