Abstract—It is well known that the manufacturing process of many industrial products requires the crane lifting and delivering. The use of crane can not only reduce the cost of manual handling, but also increase the production’s capacity. Thus, how to design an accurate, efficient and optimal crane scheduling becomes a very important issue in the industrial manufacturing process, especially to the electronic industry. This paper presents an optimal crane scheduling and control for the multiple manufacturing processes of electronic surface treatment based on the entire plant design. The expert system with “time-axis” method is used to find the minimum number of cranes needed for the entire plant design. The surface treatment of electronic industry is used as the example for the whole design process. The result shows that the optimal crane scheduling developed can not only have the optimal cranes’ control, but also fit the requirement of minimum cycling time of each manufacturing process.
Index Terms—Crane, optimal scheduling and control, expert system, time-axis.
