A framework for knowledge-based applications in pavement management.

A framework is presented for the creation of knowledge-based systems in the domain of pavement management. It uses problem solving methods in the main structuring role within the knowledge base. During the knowledge acquisition phase, the domain knowledge is identified and organized into levels of tasks. This organization enables a separation of generic knowledge, which is applicable to many tasks and specific knowledge which describes a particular task application. Such a knowledge base separation reduces knowledge acquisition time and facilitates cooperation with experts. The implementation of the above framework addresses knowledge-based applications for pavement management in Switzerland.
