Development of model for planning and controlling of operations rooms

德国的卫生系统正面临着不断增加的成本和竞争压力。因此，医院被迫重新考虑以生产力为导向的运营方式。医院的手术室是最大的增值部门，约占每位患者手术当天总费用的40%至50%。因此，最大的成本节约和提高效率的潜力是在医院的这一特殊领域。这个研究项目的目的是开发一个通用模型来规划和控制操作室。这个创新的模型将描绘计划和非计划操作的不同订单类型，而不像现有的模型只包括计划操作。因此，该模型将有助于手术室的优化规划和控制。新开发的角色模型描述了操作室中所有参与者的复杂关系和目标系统。所有行为者的目标系统将与生产控制系统相互关联，并结合为业务规划和控制的总体模式。模型内部复杂性的外部（订单类型）和内部（参与角色的目标系统）驱动因素的完整映射允许提高物流效率并降低物流成本。

The German health system is facing increasing costs and competitive pressures. As a result, hospitals are forced to rethink towards a productivity-oriented operating. The operations rooms of a hospital represent the largest value-added sector, for approximately 40 to 50 % of the total costs per patient incur on the day of surgery. Accordingly, the largest cost savings and raising efficiency potential is in this special area of a hospital.The aim of this research project is to develop a general model for planning and controlling operations rooms. This innovative model will picture different order types of planned and unplanned operations unlike existing models that include only planned operations. Thus this model will contribute to an optimized planning and control of the operations rooms. A newly developed role model depicts the complex relationships and target system of all actors in the operations rooms. The target system of all actors will be interrelated with the system of production control and combined to an overall model of operational planning and control. The complete mapping of the outer (order types) and inner (target systems of the participating roles) drivers of complexity within the model allow for improving the logistics efficiency and as well as reducing logistics costs.
