We present a computational model of treatment protocols abstracted from implemented systems that we have developed previously. In our framework, a protocol is modeled as a hierarchical plan where high-level protocol steps are decomposed into descriptions of more specific actions. The clinical algorithms embodied in a protocol are represented by procedures that encode the sequencing, looping, and synchronization of protocol steps. The representation allows concurrent and optional protocol steps. We define the semantics of a procedure in terms of an execution model that specifies how the procedure should be interpreted. We show that the model can be applied to an asthma guideline different from the protocols for which the model was originally constructed.
我们展示了一个从我们之前开发的已实施系统中抽象出来的治疗方案计算模型。在我们的框架中，一个方案被建模为一个分层计划，其中高级方案步骤被分解为更具体动作的描述。方案中所体现的临床算法由对方案步骤的排序、循环和同步进行编码的过程来表示。这种表示允许并发和可选的方案步骤。我们根据一个指定如何解释该过程的执行模型来定义一个过程的语义。我们表明，该模型可以应用于一个与最初构建该模型所依据的方案不同的哮喘指南。
