目的：在本文中，我们定义了一种原则性的方法来表示临床指南中的时间约束并进行推理（即，以约束传播的形式执行推断）。我们考虑不同类型的约束，包括复合和重复动作，并提出不同类型的时间功能（例如，背景：关于动作、持续时间、延迟和动作的周期性重复的约束是大多数临床指南的固有部分。虽然有几种方法提供了表达时态形式主义，只有少数处理相关的时态推理issues.Methodology：我们首先提出了一个时态表示形式主义和两个时态推理算法。然后，我们考虑之间的权衡表现力的形式主义和算法的计算复杂性，以设计一个正确的，完整的和易于处理的方法。最后，我们展示了如何利用这些算法来提供具有不同类型的时间facility.Results的临床指南系统：我们的方法提供了几个优点。在指南获取阶段，它能够表示时间约束，并检查它们的一致性。在执行阶段，它检查动作的执行时间与准则中的约束之间的一致性，并提供查询应答和模拟设施。(C)2006 Elsevier B.V.保留所有权利。
Objective: In this paper, we define a principled approach to represent temporal constraints in clinical guidelines and to reason (i.e., perform inferences in the form of constraint propagation) on them. We consider different types of constraints, including composite and repeated actions, and propose different types of temporal functionalities (e.g., temporal consistency checking).Background: Constraints about actions, durations, delays and periodic repetitions of actions are an intrinsic part of most clinical guidelines. Although several approaches provide expressive temporal formalisms, only few of them deal with the related temporal reasoning issues.Methodology: We first propose a temporal representation formalism and two temporal reasoning algorithms. Then, we consider the trade-off between the expressiveness of the formalism and the computational complexity of the algorithms, in order to devise a correct, complete and tractable approach. Finally, we show how the algorithms can be exploited to provide clinical guideline systems with different types of temporal facilities.Results: Our approach offers several advantages. During the guideline acquisition phase, it enables to represent temporal constraints, and to check their consistency. In the execution phase, it checks the consistency between the execution times of the actions and the constraints in the guidelines, and provides query answering and simulation facilities.
