考虑设备退化维护的医疗调度研究

Study on Patient Scheduling with Medical Device Maintenance and Variable Maintenance Duration

研究了一台医疗设备环境下,同时考虑固定周期维护且维护时间可变的退化维护,目标函数为最小化滞后医疗检查数量的调度问题,建立其数学模型,并提出了一个基于Moore算法的三阶段动态启发式算法,通过算例证明了算法的有效性。

This paper studies a single medical device scheduling problem with the objective of minimizing the number of tardy examination for a case in which periodic maintenance activities should be performed and the duration of each maintenance activity is variable, i. e. deteriorating maintenance. A mathematical model is developed and a three-phase heuristic based on Moore＇s algorithm is proposed. Finally, the effectiveness of the heuristic is verified by a series of computational experiments
