Previous studies approach surgery scheduling mainly from the mathematical modeling perspective which is often hard to apply in a practical environment. The aim of this study is to develop a practical scheduling system that considers the advantages of both surgery categorization and newsvendor model to surgery scheduling.
DESIGN/METHODOLOGY/APPROACH: The research was carried out in a Finnish orthopaedic specialist centre that performs only joint replacement surgery. Four surgery categorization scenarios were defined and their productivity analyzed by simulation and newsvendor model.
Detailed analyses of surgery durations and the use of more accurate case categories and their combinations in scheduling improved OR productivity 11.3 percent when compared to the base case. Planning to have one OR team to work longer led to remarkable decrease in scheduling inefficiency.
In surgical services, productivity and cost-efficiency can be improved by utilizing historical data in case scheduling and by increasing flexibility in personnel management.
ORIGINALITY/VALUE: The study increases the understanding of practical scheduling methods used to improve efficiency in surgical services.
以往的研究主要从数学建模的角度探讨手术调度问题，而这种方法在实际环境中往往难以应用。本研究的目的是开发一种实用的调度系统，该系统将手术分类和报童模型的优势应用于手术调度。
设计/方法/途径：该研究在一家仅进行关节置换手术的芬兰骨科专科医院进行。定义了四种手术分类方案，并通过模拟和报童模型分析了它们的生产率。
与基础案例相比，对手术时长进行详细分析，并在调度中使用更精确的病例类别及其组合，可使手术室生产率提高11.3%。计划让一个手术室团队工作更长时间可显著降低调度效率低下的情况。
在外科服务中，通过在病例调度中利用历史数据和增加人员管理的灵活性，可以提高生产率和成本效益。
原创性/价值：该研究增进了对用于提高外科服务效率的实用调度方法的理解。
