SELECTCRANE: An Expert System for Optimum Crane Selectionby Awad S. Hanna, (M.ASCE), Univ of Wisconsin-Madison, Madison, United States,
Abstract: Every major project undertaken today requires the services of a crane(s) to ensure that all materials and equipment hoisting and placement are performed in the most efficient manner. The ability to select a crane to aid in the successful and timely completion of any project requires years of knowledge and experience. The selection is influenced by such factors as project size, project terrain, size of the structures being erected, size and weight of the loads requiring hoisting and placement, etc. One way of ensuring that an adequate crane selection is achieved is to hire an individual who is an expert at crane selection or to consult with a crane rental company. This is, however, costly and may not always result in the most optimum selection. This paper presents the development of a knowledge base expert system to aid in the selection of the most adequate crane type for any project. It will describe the most commonly used types of cranes, the means by which the knowledge was acquired to build the knowledge base and the implementation of the knowledge base into an expert system for crane selection. Hence, by being familiar with the crane types available, an individual could make an appropriate selection after consulting the knowledge base and any other relevant information available to him/her.
