Abstract
In this research, the optimum design method is studied for a materials handling-carrying system in a coaling wharf which includes many probability factors. In this paper, a simulation analysis method has been established to clarify the behavior of the system. The Monte Carlo method is used to deal with probability factors in this analysis. Simulation models are proposed based on the investigation results obtained from Chinese wharfs handling the most coal in the world and Japanese wharfs where the newest materials handling machines are provided. These models are applicable to the rear handling area, yard area and berth area. Coupled behavior between the rear handling area and berth area can be considered. Materials handling-carrying machines, such as the cardumper, stacker, reclaimer, shiploader and unloader are treated as multiple element models according to their performance and arrangement. As the system is composed of these machines, the complete model is created by combining these element models. By this method, the entire system can be analyzed synthetically on coaling wharfs having various specifications. An analysis like this has not yet been conducted. It has been confirmed by queueing theory that this analysis method has no basic problems. This method can be applied to actual coaling wharfs.
