基于模型的诊断过程仅在系统描述中明确提供的情况下跟踪组件之间的连接。因此，构造断层落在网格之间。这个问题已经知道，因为研究开始在这个领域（[戴维斯84]），但没有一般的解决方案已经提出了。我们提出了一个程序来诊断结构故障，基于一个计划，以检测隐藏的相互作用的观察，结构故障导致明显不相关的领域的差异，这与[Preist. Welham 90]动态地修改系统描述。与Davis的方法一样，本文中提出的方法基于这样的原则：只有在组件以某种方式相邻的情况下才会发生相互作用（[Davis 84]）。与戴维斯的方法不同，我们引入了一个显式的表示方案隐藏的相互作用。隐藏的交互模型将所需的上下文、行为独立的星座与交互对整个系统行为的影响联系起来。为了控制隐藏的相互作用的假设，我们利用行为模式分配的基础上的诊断结构。
A model based diagnosis procedure traces connections between components only where these are provided explicitly in the system description. Consequently structure faults fall between the meshes. This problem has been known since research started in this field ([Davis 84]), but no general solution has been presented so far. We present a procedure to diagnose structure faults, based on a scheme to detect hidden interactions guided by the observation that structure faults lead to discrepancies in apparently unrelated areas and which in contrast to [Preist. Welham 90] modifies the system description dynamically. Like Davis' approach the one presented in the paper is based on the principle that an interaction can occur only where components are adjacent in some way ([Davis 84]). Unlike Davis approach we introduce an explicit representation scheme for hidden interactions. A hidden interaction model links a required contextual, behaviour independent constellation to the impact of the interaction on the overall system behaviour. In order to control hidden interaction hypotheses we exploit the structure of diagnoses based on behavioural mode assignments.
