考虑手术间及医疗团队间准备时间的手术排程

Surgical scheduling considering setup time between surgeries and setup time between surgical teams

从医疗运营的角度出发,构建了包含手术间准备时间和医疗团队间准备时间的排程模型.该模型考虑了存在于手术时间和手术间准备时间的学习效应和存在于医疗团队间准备时间的恶化效应,以最小化所有手术完成时间为目标.研究表明,当每个医疗团队按照病人基本手术时间的非减顺序进行手术,按照给定多项式的非减顺序进入手术室时,完成所有病人手术的时间最短.最后通过数值算例来模拟现实手术的排程,验证了该排程模型能有效地缩短手术完成时间.

From the perspective of hospital operation, a surgical scheduling model including the set- up time between consecutive surgeries and that between surgical teams was built up. The learning effect in both surgical duration and the setup time between consecutive surgeries as well as the deteriorating effect in the setup time between consecutive surgical teams was considered. The minimum of completion time of all the surgeries was set as the objective. The results show that the completion time is the shortest when each surgical team performs surgeries according to the non-decreasing order of normal surgical duration and all the surgical teams enter operating room according to the non-decreasing order of given multinomial. Finally, a set of numerical experiments are presented to simulate the process of surgical scheduling, proving that the proposed surgical scheduling model can shorten the surgical completion time effectively.
