小型包裹递送公司提供服务，保证在给定的时间范围内递送包裹。由于旅行时间的可变性，轴辐式交付网络的配置对于确保满足服务水平保证的高概率至关重要。我们提出了随机p-枢纽中心问题的机会约束，我们使用的模型的服务水平保证。我们讨论了分析结果，提出解决方案，并提出了计算实验的结果。
Small package delivery companies offer services where packages are guaranteed to be delivered within a given time-frame. With variability in travel time, the configuration on the hub-and-spoke delivery network is vital in ensuring a high probability of meeting the service-level guarantee. We present the stochastic p-hub center problem with chance constraints, which we use to model the service-level guarantees. We discuss analytical results, propose solution heuristics, and present the results from computational experiments.
