The uncertain factors in hospital operation scheduling process, selection of optimization problems in the risk level operation, in order to maximize the benefits of a hospital for elective surgery, in the fuzzy uncertain environment, considering the factors of time and resource constraints and risk confidence level, a fuzzy dependent chance programming model through the hybrid intelligent algorithm design to find the optimal solution of the model, finally this paper will illustrate the operability of the model, to prove the validity of the algorithm. 不确定条件下基于机会约束的医院手术调度研究 李卫宁 1 王付宇 1,2 安徽工业大学 管理科学与工程学院, 马鞍山, 安徽,中国 上海理工大学 管理学院, 上海,中国 1448522819@qq.com 通讯作者 李卫宁 关键词:模糊不确定;机会约束;手术调度;混合智能算法 摘要:医院手术调度过程中不确定因素较多,在风险置信水平下手术选择优化问题,为了最 大化医院择期手术收益,在模糊不确定的环境下,考虑了时间、资源限制和风险置信水平等 因素,建立了模糊相关机会规划模型,通过设计的混合智能算法求出模型的最优解,最后本 文将举例来说明模型的可操作性,证明算法的有效性。 1. 引言 医疗卫生市场竞争日益激烈,医院必须通过合理调度增加收益,提高病人满意度才能在 市场中占有一席之地。手术室作为医院最大的成本和收入中心,是影响整个医院的绩效的重 要方面。目前国内外相关研究人员对手术调度采用最多的方法还是通过对历史经验数据的 总结,从而分析出最合理的调度方案,使患者的手术顺序得到有效的排列。然而很多的多 医院手术调度中很少考虑在置信水平下的收益状况。本文在此基础上研究时间和费用均为模 糊的情况下,在一定的可信度(置信水平)下进行手术调度,并利用混合遗传算法解决此模 型。 129 Advances in Economics, Business and Management Research (AEBMR), volume 34 2nd International Conference on Financial Innovation and Economic Development (ICFIED 2017)
