人们对使用工作流程来描述、监测和指导医院的各种医疗程序越来越感兴趣。与完善的业务流程不同，医疗工作流程需要高度的执行灵活性，因为不可能预测可能影响其执行的所有可能情况，重要的是允许工作人员灵活应对各种情况。医疗工作流还需要不引人注目，因为要求员工不断确认任务执行或输入工作流数据将妨碍提供医疗保健。在本文中，我们提出了一种基于Teleo-Reactive程序的工作流规范的新方法，其中工作流不是被定义为一组离散的步骤，而是作为一个目标驱动的过程。工作流任务建模为连续的上下文条件或持续的操作。与传统的基于图形的工作流模型相比，TR工作流提供了高度的灵活性和更简单的方法来建模以人为中心的任务。我们将通过一个小型的普及医疗保健示例来说明该方法，并展示如何将该方法应用于管理工作流资源和安全性。
There is growing interest in using workflows to describe, monitor and direct a wide-range of medical procedures in hospitals. Unlike their well-established business counterparts, medical workflows require a high degree of execution flexibility since it is impossible to anticipate all the possible circumstances that might influence their execution and it is important that staff are permitted to respond to situations flexibly. Medical workflows also need to be unobtrusive, since requiring staff to continually acknowledge task execution or enter workflow data will get in the way of delivering medical healthcare. In this paper we present a new approach to workflow specification based on Teleo-Reactive programs, where a workflow is not defined as a set of discrete steps, but rather as a goal-driven process. Workflow tasks are modelled as continuous context conditions or durative actions. TR workflows offer a high degree of flexibility and an easier way to model human-centric tasks than the traditional graph-based workflow models. We illustrate the approach with a small pervasive healthcare example and show how we also apply the approach to managing workflow resources and security.
