Prototype Expert System for Resolution of Concrete Construction Problems

摘要

The objective of this project was to develop a prototype expert systemspecifically designed to diagnose defects involved in construction of concrete bridges, identifying their causes, recommending preventive measures, and proposing possible solutions. The system was developed using an expert system shell which is equipped with a window-based interactive user interface. The system consists of two subsystems; DIAGNOSIS and CONCLUSION. Subsystem DIAGNOSIS consists of two modules; PREDICTION and CONFIRMATION. The PREDICTION module performs three functions; distress category selection, construction condition identification, and prediction conclusion. The CONFIRMATION module verifies the conclusions from the PREDICTION module and detects the causes that have not been predicted. The CONCLUSION subsystem has two phases which allow the system to display conclusions in numerical, text and graphic forms. The display shows the construction conditions input by the user and the causes, pictures, remedial measures and cautions for concrete construction relative to the defect. The system developed is practical and useful for diagnosing a few common distresses which occur during construction of concrete bridges. The system can be continually augmented and improved by the user.
