Knowledge-based engineering (KBE) is the application of knowledge-based systems technology to the domain of manufacturing design and production. The design process is inherently a knowledge-intensive activity, so a great deal of the emphasis for KBE is on the use of knowledge-based technology to support computer-aided design (CAD) however knowledge-based techniques (e.g. knowledge management ...
Knowledge-based configuration (of complex products and services) has a long history as an artificial intelligence application area, see, e.g. [B 1] [A 1] [A 6] [A 7] [A 8] [A 9] [A 10] [A 11] Informally, configuration can be defined as a "special case of design activity, where the artifact being configured is assembled from instances of a fixed set of well-defined component types which can be ...
The knowledge base contains domain-specific facts and rules [1] about a problem domain (rather than knowledge implicitly embedded in procedural code, as in a conventional computer program). In addition, the knowledge may be structured by means of a subsumption ontology , frames , conceptual graph , or logical assertions.
Expert systems were the first commercial systems to use a knowledge-based architecture. In general view, an expert system includes the following components: a knowledge base, an inference engine, an explanation facility, a knowledge acquisition facility, and a user interface. [48] [49] The knowledge base represents facts about the world.
As knowledge-based technology scaled up, the need for larger knowledge bases and for modular knowledge bases that could communicate and integrate with each other became apparent. This gave rise to the discipline of ontology engineering, designing and building large knowledge bases that could be used by multiple projects.
For example, see the discussion of Corporate Memory in the earliest work of the Knowledge-Based Software Assistant program by Cordell Green et al. [3] The volume requirements were also different for a knowledge-base compared to a conventional database. The knowledge-base needed to know facts about the world.
Knowledge-based engineering or knowledge-aided design is a process of computer-aided usage of such knowledge models for the design of products, facilities or processes. The design of products or facilities then uses the knowledge model to guide the creation of the facility or product that need to be designed.
The requirement was for a knowledge representation framework that could support the entire life cycle: requirements, specification, and code as well as the software process itself. The core representation for the knowledge base was meant to utilize the same framework although various layers could be added to support specific presentations and ...
