The authors describe the development of a decision-support system for the preservation of civil infrastructure. The aim of the system is to provide assistance for decisions regarding the three primary tasks of infrastructure maintenance and rehabilitation: symptom observation, condition diagnosis, and treatment identification. Two techniques--knowledge graphs and damage assessment--are incorporated into the system with a uniform representation scheme to organize the knowledge and data. The architecture of the system consists of knowledge bases, databases, analysis programs, and various interfaces. A case study of the New York State Thruway is presented for illustration purposes and as a framework for discussion of the functional integrity of the system in providing assistance for data and decision needs. The authors conclude that formalization of decision methodologies in achieving the functional integrity of a decision-support system is an important contribution of the system development.
