对一个存在最大风险约束的运输网络而言,由于各路段的固有风险不同,使得运输网络的总风险会随着垃圾运输车辆在不同路段的行驶变化而变化。受网络总风险的约束,运输网络所能接纳的运输车辆总数也将处于动态变化的状态。文中针对任意起点存在运输车辆进入运输网络需求时,如何进行风险分配的问题,构造了网络优化的数学模型,并给出了模型求解的算法及不同优化策略比较分析。
對一箇存在最大風險約束的運輸網絡而言,由于各路段的固有風險不同,使得運輸網絡的總風險會隨著垃圾運輸車輛在不同路段的行駛變化而變化。受網絡總風險的約束,運輸網絡所能接納的運輸車輛總數也將處于動態變化的狀態。文中針對任意起點存在運輸車輛進入運輸網絡需求時,如何進行風險分配的問題,構造瞭網絡優化的數學模型,併給齣瞭模型求解的算法及不同優化策略比較分析。

For a transport network existing the biggest risk constraint, the inherent risk of each section is different, which makes the total risk of the transport network vary with the garbage transport vehicles travelling in the different section. Due to the constraint of the total risk of the transport network, the total number of garbage transport vehicles what the transport network can accommodate is in a dynamic state. Aiming at the problem of how to conduct risk al-location when a starting point exists a need which transport vehicles enter the transport network, this paper constructs the mathematical model of network optimization and gives the solving algorithm of the model and the comparative analysis of different optimization strategy.
