在本文中，我们调查了一个设施的位置和几个转运点，作为需要该设施服务的客户的收集点。例如，紧急服务的需求是在需要中央设施（例如医院）的服务的一组需求点处产生的。患者以正常速度转移到直升机停机坪（转移点），然后以更快的速度转移到设施。该模型涉及多个转运点和一个设施的位置。 Berman 等人研究了在已知一组请求点和设施位置时定位一个转运点的问题。 （2004a）。 Berman 等人对给定设施位置后的几个转运点的位置进行了调查。 （2004b）。在本文中，我们提出了解决该问题的启发式方法，并报告了 40 个问题测试集的计算实验。
In this paper, we investigate the location of a facility and several transfer points to serve as collector points for customers who need the services of the facility. For example, demand for emergency services is generated at a set of demand points that need the services of a central facility (such as a hospital). Patients are transferred to a helicopter pad (transfer point) at normal speed, and from there they are transferred to the facility at increased speed. The model involves the location of multiple transfer points and one facility. Locating one transfer point when the set of demand points and the location of the facility are known was investigated in Berman et al. (2004a). Location of several transfer points when the location of the facility is given is investigated in Berman et al. (2004b). In this paper, we propose heuristic approaches for the solution of this problem and report computational experiments on a test set of 40 problems.
