Knowledge-based computer-aided design of materials handling systems

A knowledge-based system called MAHDE (materials handing design) is described that was devised to assist facility designers in the selection and configuration of materials handling equipment. The system implements techniques for representing and acquiring the preferences of the facility designer. This preferential knowledge is incorporated into a knowledge-based system utilizing heuristics to update the operational knowledge about the individual design. The system utilizes preference-directed search to capture improved designs by dynamically acquiring preferences throughout the design process. An example of the application of the system to a design problem is presented
