确定分配给外科医生的合适的手术时间，并选择安排选择性病例的日期，可以最大限度地利用手术室。我们使用计算机模拟来模拟手术室调度。计算机模型的输入包括确定患者何时进行手术的不同方法（在线装箱算法），病例持续时间，患者等待手术的时间长度（2周是门诊患者认为可接受的最长时间中位数[n = 367]），每天的阻滞时间小时数以及每周的阻滞次数。为了分配阻塞时间以最大限度地利用手术室，必须指定两个参数：决定患者哪一天进行手术的方法和患者等待手术的平均时间长度。手术室的利用率很大程度上取决于，并随着患者等待手术的平均时间的增加而增加。意义：手术室的利用率可以通过以下方式最大化：根据可选病例的预期总时数为可选病例分配分区时间，在4周内提供开放分区时间的情况下，将患者安排在第一个可用日期，否则将患者安排在分区时间以外的“溢出”时间。
Determining the appropriate amount of block time to allocate to surgeons and selecting the days on which to schedule elective cases can maximize operating room (OR) use. We used computer simulation to model OR scheduling. Inputs in the computer model included different methods to determine when a patient will have surgery (on-line bin-packing algorithms), case durations, lengths of time patients wait for surgery (2 wk is the median longest length of time that the outpatients [n = 367] sun eyed considered acceptable), hours of block time each day, and number of blocks each week. For block time to be allocated to maximize OR utilization, two parameters must be specified: the method used to decide on what day a patient will have surgery and the average length of time patients wait to have surgery. OR utilization depends greatly on, and increases as, the average length of time patients wait for surgery increases. Implications: Operating room utilization can be maximized by allocating block time for the elective cases based on expected total hours of elective cases, scheduling patients into the first available date provided open block time is available within 4 wk, and otherwise scheduling patients in "overflow" time outside of the block time.
