Abstract:
This paper addresses selected aspects of diagnostic knowledge management. Not only does it introduce the process of modeling with the use of multimodal statement networks, but it also presents methods of model development, nature of its individual layers and elaborates on the construction process of diagnostic knowledge base along with its verification. The main purpose of the presented method is to aid in design of diagnostic systems for complex objects requiring inference process that takes places under condition of uncertainty with partially contradictory knowledge being observable. Chosen elements were implemented in free REx software developed in R language.
