摘要

Supply chains aim to satisfy customer demand, yet negotiated delivery quantities may differ from the originally requested amount. This study proposes a multi-objective mixed-integer linear programming model to evaluate a multi-mode demand policy considering the triple bottom line of sustainability: customer satisfaction, profit, and GHG emissions within a multimodal transportation network. The model is solved using the AUGMECON method, and three performance indicators are developed to assess economic, environmental, and social impacts. Results show a clear trade-off. The multi-mode demand policy improves profitability and reduces emissions by enabling better utilization of existing facilities and avoiding the establishment of costly high-polluting plants. However, customer satisfaction declines compared with the original demand mode because customers face shortage risk in low modes and inventory and budget burdens in high modes. Overall, flexible demand fulfillment enhances operational and environmental efficiency, while full demand fulfillment remains the most favorable option from the customer perspective.
