论文摘要
集线器位置问题在逻辑系统，航空公司行业，供应链网络设计和电信中具有多个应用程序。在集线器位置问题中，应选择许多节点作为用于充当主要分销商和其他节点的集线器节点。进入轮毂节点的输入流非常大，因此我们经常在集线器节点中面对充血，从而引起整个系统中的干扰。此外，我们的服务率不同，这是造成干扰的另一个原因，并且应该由模型解决。本文通过提供阻止系统拥塞的模型来解决这些问题。我们通过考虑多个服务器选项和不同的服务率，将排队系统纳入了P-Median集线器位置问题。 CAB数据集（包含25个美国城市）用于实施中，我们的发现显示了考虑到集线器位置网络设计的拥塞的重大影响。
Hub location problems have multiple applications in logistic systems, airways industry, supply chain network design, and telecommunication. In the hub location problem, a number of nodes should be selected as the hub nodes to act as the main distributors and other nodes are connected together by these hubs. The input flow to the hub nodes is very large so more often we face the congestion in the hub nodes that causes disturbances in the whole system. Also, we have different service rates which is another cause of disturbance and should be addressed by the models. This paper addresses these issues by providing a model that prevents congestion in the system. We incorporated queuing system in the p-median hub location problem by considering multiple server options and different service rates. CAB dataset (contains 25 US cities) was used in the implementation and our findings show the big impact of considering congestion on the hub location network design.
