Application of Expert System for Bridge Management in Papua New Guinea

This paper presents a computer aided bridge management system (CADBMS) and its implementation in the context of Papua New Guinea. The expert system includes a bridge management information system database (BMISD) and knowledge based database (KBD) logically linking all bridge parameters to the repair, maintenance and rehabilitation (RMR) options. The KBD is written in Micro-soft Excel with its Visual Basic Interface (VBI).

CADBMS is developed and implemented in some provinces and work is now under progress to develop a global system to include the whole country.
