目的 针对应急物资的供应商选择问题，希望通过与供应商之间签订柔性契约，以确保军队在应对突发灾害时能快速高效并且经济合理地获得救援物资。方法 通过建立随机规划模型，可针对不同供应商提供的协议条款选择采购成本最少的供应商。结果 运用该模型可分析得出，地处易发生Ⅰ，Ⅱ，Ⅲ，Ⅳ级灾害区域的军队采购部门在选择应急物资供应商时应重点协商的内容。结论 军队采购部门与应急物资供应商之间签订柔性契约，能在保证物资供应的前提下尽可能降低总的采购成本，从而实现双方共赢。

The work aims to sign flexible contracts with suppliers to ensure that the military can get relief supplies quickly, efficiently and economically in response to emergency disasters, with respect to the supplier selection problem of emergency supplies. By establishing the random planning model, the supplier with the lowest procurement cost could be selected according to the agreement terms provided by different suppliers. This model could be used to analyze the contents that military procurement departments in areas prone to Ⅰ, Ⅱ, Ⅲ and Ⅳ grade disasters should focus on during negotiation when selecting emergency supplies suppliers. The flexible contract signed between the military procurement department and the emergency supplies supplier can reduce the total procurement cost as much as possible on the premise of ensuring the supply of supplies, thus achieving a win-win situation for both parties.
