Abstract:A case study‐based approach was used to develop the knowledge base of an expert system for marketing media class selection. Cases, in the context of business learning, are detailed, written descriptions of business problems and their resolution. An expert system rule set was developed for media class selection using standardised business case studies. The system developed was validated using another set of case studies. Using case studies has two knowledge elicitation advantages: (1) the knowledge source is standardised and relatively unambiguous and (2) less domain expert involvement is require

摘要:

Abstract:In this article we describe how two popular AI representation techniques—frames and production systems— can be usefully combined under a general AI object‐oriented approach to problems which arise in the domain of hardware fault diagnosis. One of the main advantages of such a combination is that causal reasoning— crucial to the domain under consideration — can also be naturally and effectively represented. In order to put the combination of frames and production systems on a sound methodological footing, we first provide a knowledge engineering methodology which is an object‐oriented re‐interpretation of ontolog

摘要:

Abstract:This article describes an intelligent knowledge‐based object‐oriented process planning (IKOOPP) system for the manufacture of progressive die plates. A die assembly is designed using a variety of standardised components based on a computer‐aided design (CAD) system. A feature recognition module extracts all the pertinent geometrical properties and functional attributes of each machining feature from the CAD representation models. These properties and attributes are converted into an object‐oriented representation. Knowledge of the functions of the machining feature allows process planning information to be automatically deduced. Specialised tool engineering knowledge are formulated as production rules or procedures to establish the required set of cutting tools, together with the machining allowances and sequence of ope
