The construction of origin logistics infrastructure is essential for the sustainable development of agricultural supply chains. Against this background, we address the integrated location-allocation problem for agricultural product origin warehouses under decision-dependent demand uncertainty in a multi-product, multi-period setting. Specifically, we propose a two-stage distributionally robust optimization (DRO) model that captures demand uncertainty through a decision-dependent ambiguity set. We then transform the proposed DRO model into an exact mixed-integer linear programming formulation by leveraging duality theory and McCormick envelope techniques, which can be solved by the Gurobi solver. The computational results from an empirical study in Yunnan, China, indicate that, compared to the customer self-operated mode, the shared origin warehouse mode can reduce total construction area by 21 % and construction costs by 21.7 %, while achieving a utilization rate above 70 %. These findings demonstrate the benefits of cost-reduction and efficiency-enhancement of the shared origin warehouse mode in agricultural product distribution. Moreover, comparative analysis demonstrates the superior performance of the proposed method over traditional stochastic programming and conventional DRO models. This study presents an innovative modeling approach for addressing decision-dependent uncertainty in the sustainable development of agricultural supply chains.
