出于诊断或治疗原因，通常需要院内转运。根据医院的布局，护理病房和服务单位之间的交通要么由救护车提供，要么由经过培训的步行陪同患者的人员提供。德国许多大型医院的病人转运服务管理不善，缺乏工作流程协调。这导致更高的医院费用（例如，因为患者没有按时被送到手术室）并且给患者带来不便（例如，因为等待时间长）。我们设计了一个基于计算机的规划系统 Opti-TRANS©，它支持运输流程的所有阶段，包括旅行预订、调度运输请求以及实时监控和报告行程。我们开发的方法是为了解决潜在的优化问题（具有医院特定约束的动态叫车问题），利用快速启发式方法来确保高效、及时地提供交通。我们我...
Intrahospital transports are often required for diagnostic or therapeutic reasons. Depending on the hospital layout, transportation between nursing wards and service units is either provided by ambulances or by trained personnel who accompany patients on foot. In many large German hospitals, the patient transport service is poorly managed and lacks work-flow coordination. This contributes to higher hospital costs (e.g., because a patient is not delivered to the operating room on time) and to patient inconvenience (e.g., because of long waiting times). We designed a computer-based planning system, Opti-TRANS©, that supports all phases of the transportation flow, including travel booking, dispatching transport requests, and monitoring and reporting trips in real time. The methodology, which we developed to solve the underlying optimization problem—a dynamic dial-a-ride problem with hospital-specific constraints, draws on fast heuristic methods to ensure the efficient and timely provision of transports. We i...
