Abstract
By analyzing the current development status and existing issues of the open-loop shared pallet system, the work aims to construct a transportation model for the system, to identify a scientific and reasonable transportation plan and reduce transportation costs. Aiming at the current research gap and practical demands, an in-depth investigation was conducted into the transportation optimization of open-loop shared pallet systems under supply-demand uncertainty. With the objectives of minimizing total transportation costs and maximizing customer satisfaction, a stochastic chance-constrained programming model was constructed. The feasibility of the model was verified, and numerical examples were solved with the Gurobi solver. The findings revealed that under the supply-demand uncertainty, the proposed stochastic optimization model effectively reduced the system's total transportation costs. This provides robust theoretical support and practical solutions for enterprises to address supply-demand uncertainties and formulate more economically efficient transportation decisions within open-loop shared pallet systems.
