The Design and Realization of the Expert System of Load/Unload Operation of Quayside Crane

This article designs an expert system with real-time inquiry of quayside crane (QC) generated by utilizing a producing system. According to the operational knowledge learned from quayside crane operators, and the adoption of the forward-direction inference mechanism based on the blackboard structure, the designer, by summing up the knowledge, designs an eight-type database with relevant regulations that manifests the data with the producing method, and finally realizes the expert system under the condition of software PB9.0. Through the established database, therefore, the detailed encoding can be transferred to the specified location within the coordinate, and build up an internalized database with the Entity-Relationship Approach.
