Abstract: To promote energy conservation and carbon emission reduction,the robust optimization of location-routing problem with hierarchical capacities in distribution network design under carbon tax policy was studied.A mixed integer nonlinear programming model was proposed to describe the problem.Then,the nonlinear model was transformed into a linearized robust equivalent model based on the strong duality theory.The solver GUROBI was adopted for numerical calculation and analysis.The conclusions showed that the carbon tax policy had the effect of reducing emissions;with the increasing of carbon tax rate,the carbon emission showed a ‘step’ downward trend;the uncertain fluctuation of unit freight would affect the optimal decision of enterprises;using more vehicles within a certain range could reduce carbon emissions.The government should set a reasonable carbon tax rate according to the size and structure of the market.Enterprises could choose robust control parameters according to their decision preferences,and should make or adjust the optimal decision scheme considering the impact of carbon tax.
