Abstract: The hierarchical distributed knowledge based system functions in a machine initiated maintenance environment to provide efficient and timely maintenance of customer equipment (40-42). The hierarchical, distributed knowledge based system provides the failure evaluation function through the use of an expert or knowledge based system (11) that is installed in the customer equipment (40). This knowledge based system (11) identifies the occurrence of a failure within the customer equipment (40) and functions using its rules, hypotheses and collected data to isolate the source of the error in the customer equipment (40) and, whenever possible, ''fence'' or isolate the failed field replaceable unit that has caused the error. A significant additional attribute of this system is the provision of at least one more level (1, 30) of knowledged based system to provide a more global failure evaluation capability.

Abstract translation: 基于层次分布式知识的系统在机器启动的维护环境中起作用，为客户设备提供高效，及时的维护（40-42）。 基于层次分布式知识的系统通过使用安装在客户设备（40）中的专家或基于知识的系统（11）来提供故障评估功能。 这种基于知识的系统（11）识别客户设备（40）内的故障的发生，并使用其规则，假设和收集的数据来隔离客户设备中的错误源（40），并且尽可能地“ “围栏”或隔离导致错误的故障现场可更换单元。 该系统的重要附加属性是提供至少一个基于知识的系统的更多级别（1,30），以提供更全球的故障评估能力。

Abstract: Système expert à structure hiérarchique fonctionnant dans un programme d'entretien déclenchée par la machine elle-même, afin d'effectuer l'entretien efficace et rapide d'installations (40-42) chez le client. Ledit système remplit la fonction d'évaluation d'une panne en utilisant un système expert (11) installé à l'intérieur de l'installation (40) chez le client. Ce système expert (11) identifie l'apparition d'une panne dans l'installation cliente (40) et fonctionne en utilisant ses règles, ses hypothèses et les données recueillies pour isoler la source du défaut de l'installation (40) chez le client et, dans la mesure du possible, pour isoler le module interchangeable défectueux ayant provoqué la panne. L'avantage supplémentaire important dudit système est la présence d'au moins un niveau supplémentaire (1, 30) dans ledit système, créant une capacité complète d'évaluation des pannes.
