随着患者的临床情况随着时间的推移而变化，可以获得更多信息。某些程序需要时间来执行，导致订购测试和获得结果之间存在延迟。此外，随着患者病情随时间的变化，可以进行连续测量。更多数据的可用性可以对患者进行更准确的评估。当有更多信息可用时，在患者护理临床过程早期产生的不确定性、猜测或错误也可以被识别和解决。利用随时间变化的数据流进行推理对专家系统的设计者提出了挑战。在专家系统中使用事后诸葛亮要求适当注意数据的时间关系，并在修改决策时小心谨慎。我提出了一个数据依赖系统，即时间控制结构（tcs），旨在支持随时间变化的数据进行推理，并展示如何使用它来实现事后推理。
As the clinical picture of a patient evolves over time, more information becomes available. Certain procedures require time to perform, causing delay between the time when the tests are ordered and when the results are available. Furthermore, as the patient's condition changes over time, serial measurements can be made. The availability of more data allows a more accurate assessment of the patient. Uncertainties, guesses or errors that were made early in the clinical course of patient care can also be identified and resolved when more information is available.Reasoning with a stream of data that changes over time presents a challenge to the designers of expert systems. The use of hindsight in expert systems requires that appropriate attention be paid to the temporal relations of the data and that care is exercised in revising decisions. I present a data-dependency system, the Temporal Control Structure (tcs), designed to support reasoning with data changing over time and show how it can be used to implement reasoning by hindsight.
