Healthcare supply chains face significant challenges during epidemic outbreaks due to rapidly changing demand, supply disruptions, and limited healthcare resources. These challenges are particularly pronounced for vector-borne diseases, where healthcare resource allocation must be coordinated with vector control operations. This study develops a tri-objective mixed-integer linear programming (MILP) model for healthcare supply chain network design that jointly considers material distribution, patient transportation, resilience, and responsiveness. The proposed network consists of primary suppliers, backup suppliers, distribution centers, VCUs, communities, and hospitals. To address uncertainty in the demand, facility capacity, and transportation costs, the established robust possibilistic programming (RPP) framework with trapezoidal fuzzy numbers is incorporated into the proposed optimization model. The resulting formulation simultaneously minimizes total system cost, critical-node penalties, and response deviations while accounting for both optimality robustness and feasibility robustness through heterogeneous penalty coefficients. The augmented ε-constraint (AEC) method is used to generate the Pareto-optimal frontier and analyze the trade-offs among the robust total objective, resilience, and responsiveness. The proposed model is validated using a real-world case based on the 2025 Chikungunya fever outbreak in Shunde District, Foshan, Guangdong Province, China. The results show that the proposed framework effectively supports healthcare resource allocation under uncertainty, while the RPP model with confidence levels of α = β = 0.5 exhibits the lowest cross-scenario variability among the tested configurations. The Pareto analysis further provides quantitative guidance for balancing operational cost, resilience, and responsiveness under different epidemic response scenarios. The proposed framework offers a practical decision support tool for healthcare administrators and emergency planners facing uncertain public health emergencies.
